I am a certified interior architect and have been running the Estilo Design studio for many years. With 15 years of professional experience, I have truly seen it all. I often work on apartment renovations that were previously “designed to suit personal taste.” This is when I listen to what did not work, what was overlooked, and I can see the mistakes firsthand. Renovating an apartment is a complex process, and budgets have a curious tendency to run out faster than the contractors can apply the final coat of plaster.

So what are the most common apartment renovation mistakes – the ones that cost the most in terms of stress, time, and, above all, money?

Let’s start at the beginning. You buy an apartment and receive a beautifully designed brochure. On the floor plan, everything looks perfect – a bedroom with a generous bed, space for a desk, and a large sofa in the living room. The interior feels open and spacious. The problem is that developers are masters of optical illusion… on paper.

It’s worth remembering that furniture shown on floor plans is often not drawn to scale. In reality, it is much larger and may simply not fit into the finished room. If the building is still under construction, this is the moment to consider developer layout changes. Moving a partition wall by a seemingly insignificant 15 centimetres costs very little at this stage. Later, once the plasterwork is complete, the same change becomes far more expensive, as it usually involves modifying installations as well. Without a professionally designed functional layout, it is easy to end up with a bedroom where a real, upholstered bed – not just a simplified mattress on a drawing – completely blocks access to the wardrobe.

A mistake that quickly becomes apparent – often within the first month after moving in – is the lack of well-thought-out storage solutions. We buy individual dressers because they are charming, only to discover that the ironing board permanently lives behind the door and half of our belongings are left out because they have no proper place. One well-designed built-in unit from floor to ceiling is worth more than five mismatched designer cabinets, which create visual chaos rather than order.

Ergonomics is the key word. A missing functional layout during the stage of moving walls can lead to later problems. You may find there is no space for a home office, or movement in the bedroom is awkward because of those critical 15 centimetres that seemed unnecessary in the adjacent room. Another classic? Light switches positioned behind wardrobes or the absence of an outlet where the kettle happens to sit.

Expert tip: Choosing furniture that is inappropriate for the size of the room disrupts both ergonomics and visual harmony. Always check the actual dimensions of a piece and see how it fits in the space before buying.

It’s also worth looking ahead. Smart home technology and high-efficiency LED lighting are now standard, not a luxury. Ignoring these solutions can be a mistake that may reduce your apartment’s value if you decide to sell in the future. Plan your installations for smart systems now – even if you only intend to use them later.

Often, we try to fit every Pinterest inspiration into a single apartment. We attempt to combine a raw loft style with cozy Japandi and a touch of glamour. The result? Stylistic chaos.

The biggest aesthetic mistakes:

• Color chaos: Five different types of wood in one room is at least three too many. Choosing pieces individually, without checking how their textures and tones work together, is rarely a good idea.
• Inappropriate wall colors: Too dark or overly bright shades on large surfaces can overwhelm even the most spacious interiors. On the other hand, don’t be afraid of wallpaper – it adds warmth and elegance, as long as it isn’t too loud.
• Incorrect focal points: If the first thing you notice upon entering the living room is a huge black fridge, that’s not elegance. In an interior, not everything should demand attention. Ideally, only one or two elements should stand out (for example, a beautiful sofa corner or a table with a designer lamp) – the rest should provide a subtle backdrop.
• Fragmented flooring: Different tiles in every room visually break up and shrink the space. If you have porcelain tiles in the hallway, consider continuing them into the bathroom, toilet, or kitchen. In bedrooms, use the same parquet as in the living room. A uniform floor “enlarges” the apartment.
• Neglected accessories: Lack of curtains makes a room feel unfinished. A curtain rod hung too low visually lowers the ceiling. A single tiny picture on a large wall simply looks sad. Scale matters!
• Avoid ready-made furniture sets from catalogs: An apartment should have character, not look like a 1990s furniture showroom.

Interiors on Pinterest are often AI-generated or depict spaces twice the size of our own. There isn’t always room for a dream kitchen island, even if it looks amazing in the photo. Be cautious of micro-trends that quickly become passé.

Functionality comes first: black or white glossy countertops and floors may look stunning – for about five seconds after cleaning. After that, every fingerprint shows. And most importantly: don’t design your home according to the wishes of neighbors or in-laws. Everyone has a different lifestyle and different needs. This is your space – you should feel good living in it.

The lack of a budget buffer is mistake number one. Unexpected expenses will always arise, so it’s wise to plan for them. Where should you not skimp? Invest in items that are not easily replaceable. Flooring, doors, built-in furniture, and concealed plumbing fixtures are long-term elements. Tables, chairs, rugs, or lamps can be bought more affordably and replaced over time. And please, be cautious with “the cheapest contractors” – corrections usually end up costing twice as much as the work of a reliable team.

Skipping the help of an interior designer is often an economic mistake. A professional will not only ensure aesthetic appeal but also protect you from costly errors. If you feel overwhelmed by the process, take a look at my comprehensive interior design services – I would be happy to guide you through it stress-free.

Remember, your home is your safe haven. It should be comfortable, functional, and above all… for you.

If you need professional support that will give you peace of mind and save you valuable time during your project, I invite you to get in touch.

Let’s be honest – Artificial Intelligence promises to save both time and money, serving up a kitchen or bathroom visualization in the blink of an eye. And at first glance, that argument sounds incredibly convincing. It immediately raises the key question: do I really need to hire a designer if I can see my dream space for a fraction of the cost?

I am a certified interior designer, and for many years I’ve been running my studio, Estilo Design. I genuinely enjoy AI and often turn to my favourite helpers – ChatGPT or Gemini (always eager, always ready to offer a million suggestions while assuring me my question is fantastic 😉). But I also know these tools have their limits. So the question remains: is it still worth hiring an interior designer when AI is free?

Artificial Intelligence is a fantastic tool, especially when you need quick inspiration or an early reality-check for your ideas. With just a few clicks and a short description, you can instantly see how a chosen wall colour would look in your bedroom. AI will also serve you japandi concepts, scandinavian minimalism, or bold glamour visions – often within a minute. The algorithm never gets tired, and it will certainly never refuse when you ask for “one more version, but with a hint of pink.” When it comes to speed and the sheer number of visual proposals, AI is truly unbeatable. The question is: are these beautiful images enough to turn the design into a real, livable space?

When it comes to trend analysis and statistics, AI also shines. Algorithms review thousands of interiors every single day, while a designer might study a dozen. AI works at lightning speed, 24/7, with no operational costs and no emotional blocks. In tasks that are repetitive, large-scale, or highly formulaic – it will always come out ahead.

Well, for now AI is an excellent graphic artist – but it is not an engineer. So where do the algorithm’s fundamental limitations lie?

• Structural Limitations: The program has no understanding of what is a load-bearing wall and what can be moved. It won’t account for the fact that relocating a toilet by a few meters is impossible in an apartment building.
• Dimensions and Ergonomics: An AI-generated visualization can be beautiful, but very often it’s unrealistic. The algorithm doesn’t calculate whether a wardrobe will fit – or if there will be enough space to move freely once it’s opened.
• Budget vs. Reality: AI can effortlessly place the most expensive stone in the world on your floor – simply because it has no access to actual prices. It generates materials or solutions that, from a budgetary perspective, are pure fantasy, leaving you with a visualization that cannot be realized.

This is exactly what an interior designer takes care of. Moreover, while an algorithm can provide a visualization, only a designer can give you a complete set of construction documents – without which even the most beautiful render will never become a real, livable space. If your budget doesn’t allow for a full design, it’s worth considering, for example, a functional design package, which I offer in my studio. At a very reasonable price, it provides a comprehensive solution for all layout and space-optimization issues, complete with installation documentation.

When we compare creating beautiful images with real interior design, something equally important emerges beyond technical aspects: personalization – human life. To craft a thoughtfully designed interior that truly fits you, it’s not enough to know which color is trendy. A designer, through conversation with you, can sift through the flood of information (and a thousand Pinterest inspirations) to uncover what truly means personal comfort for you. Here lies the key difference: AI visualizations are formulaic, lacking your history, taste, or daily routine. A real interior designer doesn’t just impose a style – they integrate that style into you and your unique space.

Moreover, a designer works with specific, available products – real items that exist in store offerings. Importantly, these are chosen not only based on your budget and quality standards but, above all, according to your taste and personal style.

Finally, we come to the phase that clients often find the most stressful: project execution. Above all, we provide more than just a beautiful image – we create a complete set of documentation, including detailed installation plans, paint color codes, precise tile schedules, and material calculations. Moreover, an algorithm will never recommend a trusted professional or help coordinate work between an electrician, plumber, and plasterer. A designer has an entire network of contacts and spares you the chaos of endless phone calls. AI cannot provide on-site supervision: it won’t verify whether grout lines are the correct width, check the proper installation of wall coverings, or ensure the accuracy of tilers’ work. This kind of support and oversight guarantees a tremendous saving of nerves, time, and money.

So, is free AI really a true saving? At first glance, it might seem so, but in practice, it’s quite different. Lack of knowledge and experience in interior design can end up costing far more than hiring a designer. Algorithms often generate visualizations with technical errors or impractical solutions. Any mistakes mean costly changes during construction. AI can give you a glimpse of inspiration, but a professional design is simply an investment in your comfort and peace of mind.

So far, I’ve been discussing the current situation, but we all know how rapidly technology evolves. Should interior designers fear that free AI apps will soon replace them in the market? In my opinion – no.

AI will likely take over 30 – 50% of the “technical” and repetitive work, such as initial functional layouts, quick visualizations, searching for similar products, or cost estimates with up-to-date prices. But this is not the essence of an interior designer’s work – it’s the back office. Designers will become more like directors. Instead of creating everything from scratch, we will select, refine, adjust, provide direction, and personalize everything for the individual. This shifts our work to a higher level: style, vision, taste, intuition, and experience – areas where AI is still weak.

Clients will indeed use AI tools, but mainly for fun or as a preliminary brainstorming aid. In the end, they will still come to a designer asking: “I don’t know what to choose; I need someone to guide me.” In a world flooded with billions of similar, statistical visualizations, the human role becomes even more important. People will seek authenticity, personal style, and the touch of an artist – someone who can create a space that is unique and refined, not just “correct.” It’s exactly like photography: although everyone has a smartphone, premium photographers today have more work than ever.

AI, indeed, works wonderfully as a tool for preliminary brainstorming and trend analysis. But when a vision needs to be transformed into a real, functional, and personalized space, human work is indispensable. A true design combines technical knowledge (construction documentation), personal intuition (empathy, taste), and solid logistics (budget, supervision). This very combination ensures that your home is not a formulaic render, but a space with soul – safe, budget-friendly, and (most importantly) a shield against renovation chaos.

At the same time, it’s worth facing the truth: AI will become an invaluable aid for those for whom professional design services have so far been financially out of reach. We can expect artificial intelligence to take over the low-budget design market, where price is the main priority. Moreover, it is crucial for designers to train and fully harness the potential of evolving AI. Otherwise, the risk of losing competitiveness for those who fall behind in progress may increase.

In this article, I will share how to furnish a rental apartment so that it quickly finds tenants, makes a good impression, remains functional, and at the same time generates a satisfying profit. I will focus on furnishing an apartment for long-term rental – for people who will be living there on a daily basis. This is a completely different challenge compared to preparing a property for short-term rental, where other aspects matter: a different standard of equipment, more frequent cleaning, and a more hotel-like approach to decoration and accessories. I will cover the topic of short-term rentals in a separate article. Here, however, you will find practical tips on how to create an interior that attracts reliable long-term tenants and allows you to enjoy a stable return.

I am a certified interior architect and a graduate of the Faculty of Interior Architecture at the Academy of Fine Arts in Warsaw. I run my own studio, Estilo Design, and for many years I have also been supporting owners of investment properties. I design rental apartments that not only look beautiful but, above all, rent out successfully. From experience, I know that a well-designed interior pays for itself very quickly. A thoughtful layout, the right choice of materials, and functional solutions often determine whether an apartment will generate steady profit… or rather constant problems and costs. Such a space not only attracts reliable, responsible tenants but also allows you to achieve a higher rental price and minimize vacancy periods.

If you need professional assistance in preparing your apartment for rent, I can provide support tailored to your needs – from consultations to a full interior design project that comprehensively prepares the property for rental.

Today, I would like to share my tips on how to get an apartment ready for tenants – making it functional, beautiful, and simply enjoyable for the people who will live there.

The very first and absolutely crucial step is to answer the question – who will be your potential tenant? This is the starting point. An apartment for a single person, who needs a compact and functional space, will look completely different from one for a couple working remotely, who must fit in two desks and a place to relax. A family with a child, on the other hand, has different priorities – comfort, storage, and living space come first. Matching the functions, layout, and character of the interior to the tenant profile is the foundation of successful renting.

It is also worth carefully analyzing the market in a given district or city, checking current rental prices as well as the expected standard and equipment of apartments. This way, you can better tailor your investment to the real needs of tenants, which may shorten the rental time and reduce vacancies.

At the very beginning, it is worth carefully analyzing the layout of the rooms. Is it truly optimal? Does it meet the needs of a future tenant? What the developer or previous owner suggests is not always the best solution. Sometimes it takes very little – shifting a door, changing the function of a room, or cleverly using an alcove – to make the apartment significantly more comfortable, both for everyday living and for keeping things organized.

Ask yourself a few questions:

• Is the kitchen comfortable and functional enough?
• Does the living room offer space for both relaxation and work?
• Is there room in the bathroom to store cosmetics, cleaning supplies, toilet paper, towels, etc.?
• Are the clearances between cabinets, furniture, and walls adequate?

And one more thing – storage. This is a key word in the world of long-term rentals. Tenants bring their whole lives with them: wardrobes for all seasons, suitcases, sports equipment, sometimes a stroller, sometimes a bicycle. If you ensure that there is space in the apartment to store all of this, you gain a significant advantage on the market. An apartment with good storage space rents faster and for a higher price.

Beyond the typical practical aspects, a rental apartment should also be comfortable and convenient for everyday use. Potential tenants will certainly appreciate clever, often inexpensive solutions that make daily life easier and more enjoyable, making the property more attractive. Examples include subtle floor-level lights with motion sensors for nighttime use – they allow tenants to safely reach, for instance, the bathroom without fully waking up. Proper placement of sockets and switches can also greatly enhance the comfort of future residents.

At this early stage, it is worth considering professional support, as decisions regarding the apartment’s layout and the placement of installations are difficult to change later. My functional design package, offered at a very attractive price, allows you to comprehensively resolve all issues related to the interior layout and optimal use of space – without the need to invest in a full, comprehensive design project. This is a great solution when arranging a rental apartment if you don’t want to invest heavily but still want a functional, comfortable, and appealing property.

In recent years, more and more people have been working remotely, which is why tenants particularly value apartments with a dedicated workspace. Even a small corner with a desk, a comfortable chair, good lighting, and a reliable internet connection can significantly increase the appeal of the property in the eyes of potential tenants. It is worth considering this already at the stage of planning the apartment layout to ensure the proper installations are in place from the start.

This is one of those decisions where apparent savings can quickly backfire. While in our own homes we may overlook small imperfections and take care of repairs as they arise, in a rental property literally everything is tested. So what should you prioritize when furnishing an apartment for rent? Above all, choose durable, easy-to-maintain materials – resistant to moisture, dirt, and everyday use. At the same time, it is wise to avoid solutions that wear out quickly and require frequent replacement.

• Floors: The best choice is vinyl panels – waterproof, scratch-resistant, quiet, and durable. They can be used consistently throughout the apartment without dividing rooms.
• Walls: High-quality, washable paints with increased resistance.
• Kitchen and bathroom: Porcelain tiles, countertops made of conglomerate, sintered stone, or HPL laminate – durability is key here.
• Furniture: Simple, solid models made from easy-to-maintain materials. Smooth fronts make cleaning easier, and elements that can be easily repaired or replaced extend the life of the interior. Avoid furniture made of thin boards, which wear out quickly.

This does not mean you need to invest in luxury solutions. It is about making smart choices – aesthetic, durable, and timeless. These choices help avoid costly repairs and ensure comfort for both you and your tenants.

If you need support in choosing materials and furnishings for a specific rental apartment, I would be happy to offer guidance during a consultation – a great way to avoid costly mistakes and save time. I can recommend practical and durable solutions tailored to your budget.

How to furnish a rental apartment so that it catches the eye and looks appealing? The key is neutrality – which does not mean boring. A versatile interior can be both stylish and inviting – just one designer piece of furniture, an interesting lamp, or a few tasteful accessories can make a difference. It is also worth matching the aesthetic of the furnishings to the profile of future tenants. My general tips on the aesthetics of a rental apartment are:

• From my experience, most of us enjoy bright, modern, and airy interiors, which gain warmth and a welcoming character through cozy accents.

• Natural, warm tones work best – white, off-whites, light greys, and warm wood. These create a space that feels open and allows the tenant to bring a piece of themselves into it.

• Lighting is extremely important – well-planned illumination can completely change the perception of a room. Warm, diffused light or focused lamps create an elegant and cozy atmosphere.

• The first impression when entering the apartment is crucial. Decisions about liking the interior are often made within a few seconds, so it is worth ensuring that the entrance, and especially the first area visible, is aesthetically pleasing and stylish. From the very threshold, such an arrangement builds a positive attitude in potential tenants.

• Soft fabrics, rugs, curtains, or small accessories with interesting textures that invite touch enhance the comfort of the apartment and create an atmosphere that encourages staying and relaxing.

• Pay attention to scents – natural and subtle is best. Inexpensive yet elegant room perfumes or a scented candle can add a pleasant atmosphere. This makes the apartment feel more comfortable and perceived as more attractive by potential tenants.

• Generally, everyone enjoys spacious interiors, so consider using mirrors to visually enlarge the apartment, as well as lightweight furniture with modest proportions.

It is worth remembering that a cohesive, well-designed apartment immediately stands out among hundreds of similar listings and elevates its standard. Sometimes it is the small details that make a huge difference – an elegant baseboard, doors flush with the wall without trims, higher-quality cabinet handles, neatly installed LED lighting. Importantly, these don’t have to be expensive elements. Often, it is precisely these small but thoughtful touches that make an apartment stand out and more appealing.

If you are not confident about current trends or what appeals to tenants, it is worth consulting an interior architect, who can advise you on these matters and also point out specific products or stores – saving you a lot of time in the process.

More and more tenants appreciate everyday convenience. This is not about expensive smart home systems, but simple, practical solutions that genuinely enhance the comfort of living.

• Motion sensors in the hallway or at the entrance with connected lighting – a small detail that anyone returning with groceries will appreciate.
• LED lighting – energy-efficient, durable, and aesthetically pleasing.
• Household appliances with a high energy rating – not only more eco-friendly, but also meaning lower bills for the tenant.
• Faucets with flow restrictors, dual-flush toilets, air conditioning with an inverter function – all of these increase comfort and are highly valued.

These elements often make the decisive difference when choosing a particular rental apartment. They show that the owner has truly cared about comfort – both their own and that of the tenant.

What to Avoid – A List of the Most Common Mistakes:
❌ Colors that are too dark or loud – tiring, overwhelming, and visually shrinking the space.
❌ Overloading with furniture and decorations — less is more.
❌ Low-quality materials – savings that quickly backfire.
❌ Poor functional layout – for example, an oversized hallway at the expense of the living room.
❌ Thoughtless following of trends – something popular today may be outdated next year.

It is the photos that sell your apartment. Even the most beautiful design will not fulfill its purpose if the interior looks dull, dark, or simply unappealing in photographs. That is why I provide every client with contact to a professional interior photographer I have worked with for years. This is not an extra – it is an absolutely key part of the entire process. Good photos attract attention and help achieve a better rental price.
