Renovating a Studio Flat in 2026: A Complete Guide | Mudelar

As a technical lead at Mudelar, I've overseen countless renovations in Porto and across northern Portugal. Renovating a studio flat or a one-bedroom (T1) apartment presents a unique set of challenges and opportunities. It's a game of inches, where every decision impacts the final feeling of space and light. Many clients feel daunted by the prospect, but I assure you, with a smart plan, it’s one of the most rewarding projects you can undertake. A well-executed T0 or T1 renovation can dramatically increase your property's value, improve your quality of life, and create a highly functional, beautiful home. In this guide, I'll walk you through the entire process, from initial design concepts and budgeting to material selection and construction timelines.

Quick summary

• Strategic Planning is Everything: For small spaces, the layout is paramount. Prioritise multifunctional zones, clever storage solutions, and a cohesive lighting plan before any work begins.
• Budget with Precision: The cost of renovating a studio flat can vary significantly. A full 'gut' renovation in Lisbon or Porto will differ from a cosmetic update in Aveiro. Define your scope early on.
• Material Selection is Crucial: Choose durable, light-reflecting materials. Continuous flooring, for example, creates an illusion of a larger space, while quality fixtures add long-term value.
• Focus on the 'Value Triangle': The kitchen, bathroom, and built-in storage are the three areas that provide the most significant return on investment and daily functionality.
• Understand the Timeline: A complete renovation of a T0/T1 apartment typically takes 8 to 12 weeks, depending on the complexity and any necessary permits from the local Câmara Municipal.
• Don't Underestimate 'Hidden' Systems: Upgrading old electrical wiring and plumbing is a non-negotiable for safety, compliance, and future-proofing your home.
• Turnkey is Simpler: Working with a single company like Mudelar for design, management, and construction streamlines the process, saving you time and stress.

Why Renovate Your Studio or 1-Bed Flat?

Renovating a smaller property isn't just about aesthetics; it's a strategic investment. In competitive rental markets like Lisbon and Porto, a modern, well-designed T1 can command significantly higher rental yields and attract better tenants. For homeowners, the motivation is often more personal: transforming a cramped, dated apartment into a functional and peaceful sanctuary. This process addresses years of wear and tear, updates failing plumbing and electrical systems, and radically improves day-to-day living.

Many older apartments in Portugal, particularly in areas like Sintra or central Braga, have layouts that don't suit modern lifestyles. They often feature small, dark rooms and wasted corridor space. A renovation allows you to rethink the entire floor plan. By removing non-load-bearing walls, you can create a bright, open-plan living area that feels much larger than its square meterage suggests. This is not just a trend; it's a practical response to living in compact urban environments.

The T0 vs. T1 Difference in Renovation Approach

A T0 (studio) and a T1 (one-bedroom) require slightly different strategies. With a T0, the primary goal is creating clear 'zones' for living, sleeping, and cooking within a single space. This can be achieved with clever furniture placement, glass partitions, or different flooring materials. For a T1, the challenge is often maximising the living area and bedroom, which might involve reconfiguring the wall between them or incorporating smart storage solutions like built-in wardrobes to free up floor space.

Maximising Rental Yield

For property investors, the numbers speak for themselves. A renovated apartment not only rents faster but also achieves a higher return. Key features that attract premium tenants include a modern kitchen with efficient appliances, a stylish bathroom with good lighting and ventilation, and durable, easy-to-clean surfaces. Investing in soundproofing, especially in older buildings in busy city centres, can also be a major selling point that justifies a higher rent. The goal is to create a turnkey-ready space that prospective tenants can envision themselves living in immediately.

The Planning Phase: Designing for Small Spaces

Success in renovating a studio flat is 90% planning. Before a single wall is touched, we need a clear, detailed plan that addresses layout, light, and storage. The goal is to create a space that is not just beautiful but also works effortlessly. This means thinking about how you move through the space, where you'll store your belongings, and how natural and artificial light will interact with the room. Every centimetre counts, and a good design maximises each one.

An open-plan layout is almost always the best approach for T0 and T1 apartments. Removing the wall between a small kitchen and living room can transform two cramped rooms into one spacious, sociable area. However, it requires careful planning of plumbing and electrical points. A detailed lighting plan is equally critical. We use a layered approach, combining ambient (main ceiling lights), task (under-cabinet kitchen lights, reading lamps), and accent lighting (to highlight artwork or architectural features) to create depth and mood.

Multifunctional Furniture and Built-ins

Standard, off-the-shelf furniture can be inefficient in a small flat. This is where custom built-ins and multifunctional pieces shine. Think of a media unit that incorporates a fold-down desk, a bed with integrated drawers underneath, or a bench seat with hidden storage. At Mudelar, we often design and build bespoke joinery that fits a space perfectly, turning awkward corners into valuable storage and ensuring a clean, uncluttered look. This is one of the most effective strategies for maximising functionality.

Choosing a Colour Palette to Create Space

The old advice of 'paint it all white' has some merit, but modern design offers more sophisticated solutions. A light, cohesive colour palette is essential. Using the same colour on walls, skirting boards, and even ceilings can blur the lines and make the space feel larger. We often recommend a palette of soft neutrals (off-whites, light greys, muted beiges) and using a slightly darker shade on one feature wall to add depth without overwhelming the space. Mirrors are another classic trick; a large, well-placed mirror can double the visual space and reflect light.

Core Renovation Areas: Kitchen and Bathroom

In any apartment renovation, the kitchen and bathroom are where you get the most 'bang for your buck'. These are complex areas involving plumbing, electricity, and specialised finishes, and upgrading them has the biggest impact on both property value and your daily comfort. In a studio or 1-bed flat, they need to be hyper-efficient, durable, and stylish.

The modern kitchen in a small flat is compact but mighty. We prioritise a smart layout—often a single-wall or L-shape configuration—and use every trick to maximise storage. Think pull-out pantries, corner carousels, and deep drawers instead of cupboards. We specify durable worktops like engineered quartz (from brands like Silestone or Compac) that can handle daily life. Compact appliances are a must, but that doesn't mean compromising on quality. A well-designed small kitchen is a pleasure to cook in.

Materials for Small Kitchens: What Works Best?

Material choices here are key. For cabinets, we often use moisture-resistant MDF with a high-quality lacquer or laminate finish from brands like Egger. They are durable, easy to clean, and come in countless colours. For backsplashes, large-format tiles or a single slab of the worktop material create a seamless, modern look with fewer grout lines to clean. Good under-cabinet LED lighting is non-negotiable; it illuminates the workspace and makes the kitchen feel more open.

Bathroom Layouts for Maximum Functionality

Small bathrooms require ruthless efficiency. We often recommend replacing a bathtub with a spacious walk-in shower with a frameless glass screen, which visually opens up the room. Wall-hung toilets and vanities (from trusted brands like Roca or Sanindusa) are a brilliant solution because they free up floor space, making the room feel larger and much easier to clean. Good ventilation is critical to prevent mould, as is excellent lighting around the mirror. High-quality taps and fixtures, for example from Grohe, provide a touch of luxury and are built to last.

Flooring, Walls, and Ceilings: The Foundation of Your Design

The surfaces that enclose your space—floors, walls, and ceilings—define its character. In a small apartment, the goal is to create a continuous, flowing feel. Disparate flooring materials chop up a space and make it feel smaller. By choosing one type of flooring and running it throughout the living area, kitchen, and hallway, you can create a powerful illusion of spaciousness.

For flooring, we often recommend a high-quality AC5 laminate (like those from Kronospan) or Luxury Vinyl Tile (LVT). Both are extremely durable, water-resistant, and available in realistic wood or stone finishes. They can be laid over existing tiles in some cases, saving time and demolition costs. In the bathroom, rectified porcelain tile is our go-to. The precise square edges allow for very thin grout lines, creating a clean, almost seamless surface that is both waterproof and stylish.

Soundproofing a Flat: A Worthy Investment

Living in an apartment building in a dense area like Setúbal or Amadora means dealing with neighbours. Noise transmission can be a major issue in older buildings. During a renovation is the perfect—and often only—time to address it. We can add acoustic insulation to walls (especially party walls) and ceilings. For floors, an acoustic underlayment beneath the new laminate or LVT can make a world of difference, reducing both impact noise (footsteps) and airborne noise. It's an invisible upgrade that dramatically improves quality of life.

Choosing the Right Paint and Finishes

Never underestimate the power of paint. As mentioned, a light, neutral palette is your best friend. We use high-quality, washable paints for walls, which is essential in a smaller space that sees more wear. For a touch of sophistication, consider a feature wall with textured wallpaper or a different paint finish, like a soft sheen. Ceilings should almost always be painted a flat, brilliant white to maximise the feeling of height and airiness.

Upgrading 'Hidden' Systems: Electrical and Plumbing

What lies behind the walls is just as important as what you see. In many older Portuguese apartments, the plumbing and electrical systems are dangerously outdated. A full renovation is the ideal opportunity to bring everything up to modern safety standards. Ignoring this is a false economy that can lead to serious problems down the road.

A full electrical rewire involves replacing old fabric-coated wiring with new, properly earthed cables. We'll install a new consumer unit (quadro elétrico) with modern circuit breakers and ensure there are enough sockets for a modern lifestyle—no more extension cords! This is also the time to plan for internet/TV points and any smart home features. All electrical work must comply with Portuguese regulations and be carried out by a certified electrician. It's a matter of safety and compliance.

The Cost vs. Benefit of a Full Rewire

Clients sometimes question the need for a full rewire, especially as it adds to the cost and complexity. However, the benefits are immense. It guarantees the safety of your home, prevents electrical faults, allows you to use modern appliances without issue, and adds significant value to the property. An outdated electrical system is a major red flag for any potential buyer or surveyor, and a new certified system provides complete peace of mind.

Water Efficiency and Modern Plumbing

Similarly, old galvanised or lead pipes can corrode, affecting water pressure and purity. We replace these with modern PEX or multilayer pipes, which are durable, flexible, and safer. During this phase, we can also move plumbing connections to optimise the kitchen or bathroom layout. This is also a perfect time to install water-saving fixtures, such as dual-flush toilets and low-flow taps, which can reduce your utility bills and are better for the environment, aligning with regulations like DL 118/2013 regarding energy and water efficiency in buildings.

Timeline: How Long Does a T0/T1 Renovation Take?

Understanding the timeline is crucial for managing your expectations and planning logistics, like temporary accommodation. A full 'gut' renovation of a studio or 1-bed flat (approx. 40-60m²) is a complex process and typically takes between 8 and 12 working weeks. This can be affected by the scope of work, permit approvals from the Câmara Municipal in your area (e.g., Lisbon vs. Loures), and the delivery times for specific materials like custom joinery or imported tiles.

Here’s a typical phased breakdown:

1. Week 1-2: Demolition & First Fix Preparation. This involves removing old tiles, kitchens, bathrooms, non-load-bearing walls, and flooring. It's a noisy, dusty phase, but it's quick. The space is cleared and prepared for the new layout.
2. Week 3-4: The 'First Fix' - Plumbing & Electrical. This is a critical phase where new pipes and electrical conduits are run through the walls and floors. It requires careful coordination between the plumber and electrician.
3. Week 5-6: Plastering, Walls & Ceilings. Once the 'first fix' is complete and inspected, the walls are closed up, plastered, and skimmed to create a smooth surface for painting. False ceilings are also installed at this stage.
4. Week 7-9: The 'Second Fix' & Finishing. This is where the apartment starts to look like a home again. Flooring is laid, doors are hung, and the kitchen and bathroom start to take shape. Electricians install sockets and light fixtures, and plumbers connect sinks, toilets, and showers.
5. Week 10-12: Joinery, Painting & Final Touches. The final phase involves installing built-in wardrobes and any custom joinery. The entire apartment receives its final coats of paint. This is followed by a 'snagging' period, where we meticulously check every detail before the final handover.

How much does it cost? Indicative prices in Portugal (2026)

This is the most common question I get asked. The final cost for renovating a studio flat depends heavily on the scope, material choices, and location. Prices in central Lisbon or Porto are generally higher than in surrounding areas. The table below provides a realistic guide for a 40-60m² apartment. All prices are indicative and exclusive of IVA (VAT).

Quick comparison: Flooring for Small Apartments

Choosing the right flooring is a critical decision in a small space. Here’s a comparison of three popular and practical options we recommend at Mudelar.

Common mistakes to avoid

Over the years, I've been called in to fix projects that went wrong. Here are the most common mistakes I see when people tackle a T0 or T1 renovation:

1. Ignoring Storage. People focus on the kitchen and bathroom and completely forget where they will put their vacuum cleaner, luggage, and clothes. A robust storage plan involving built-in solutions is essential from day one.
2. A Poor Lighting Plan. Relying on a single, central ceiling light is a classic error. It creates a flat, harsh light and leaves corners in shadow, making the space feel smaller and less inviting.
3. Choosing Bulky Furniture. In a small flat, furniture needs to be proportionate. Oversized sofas or heavy, dark wood tables can dominate a room and make it feel cramped, no matter how well it's renovated.
4. Not Upgrading 'The Invisibles'. Skimping on a full electrical and plumbing upgrade in an old building is a huge mistake. It's unsafe, and fixing problems later will mean ruining your newly finished walls and floors.
5. Too Many Finishes. Using different flooring in every area, or too many clashing colours and textures, visually fragments the space. Simplicity and continuity are your allies in making a small flat feel serene and spacious.
6. Underestimating the Timeline and Disruption. A full renovation is not a quick weekend job. Failing to plan for the dust, noise, and the need for alternative accommodation can lead to immense stress.

Pre-project checklist

Before you start, work through this checklist to ensure you're prepared.

• [ ] Define Your Budget: Be realistic about what you can spend, and always keep a 10-15% contingency fund for unexpected issues.
• [ ] List Your 'Must-Haves' vs. 'Nice-to-Haves': This will help you and your contractor prioritise when making budget decisions.
• [ ] Create an Inspiration Board: Collect images from magazines or Pinterest. A visual guide is incredibly helpful for communicating your desired style.
• [ ] Check Your Condominium Rules: Inform yourself about regulations regarding noise, working hours, and use of common areas like elevators.
• [ ] Measure Everything Twice: Create a simple floor plan of your existing space with accurate measurements.
• [ ] Consider Your Lifestyle: How do you live? Do you work from home? Do you entertain? The design should support your daily life.
• [ ] Investigate Permit Requirements: For layout changes, you'll need an architect and a municipal license. Clarify this early with your local Câmara.
• [ ] Get a Professional Consultation: Even if you plan to manage it yourself, an initial consultation with a company like Mudelar can provide invaluable insight.

Frequently asked questions (FAQ)

How much does it cost to completely renovate a T1 in Porto?

On average, a full gut renovation for a 50m² T1 in Porto can range from €25,000 to €40,000 for a mid-range finish in 2026. This includes new plumbing, electrics, a new kitchen and bathroom, flooring, and painting. High-end finishes with custom joinery and premium materials will cost more.

Do I need a license to renovate my apartment in Portugal?

It depends. For simple cosmetic works like painting or changing flooring, no license is required ('obras de conservação'). However, if you plan to change the layout (move walls), alter the building's facade, or make structural changes, you will need to submit a project to the local Câmara Municipal and obtain a license ('licença de obras').

How long does a studio renovation take from start to finish?

A typical studio apartment (30-45m²) undergoing a full renovation will take approximately 8 to 10 weeks. This includes demolition, new systems installation, plastering, finishing, and painting. The timeline can extend if custom-made items have long lead times or if planning permission is required.

Is renovating a small flat in Lisbon a good investment?

Absolutely. In a high-demand market like Lisbon, a renovated apartment stands out. It not only increases the property's capital value but also significantly boosts its rental potential, attracting higher-quality tenants and yielding a better return on investment. The key is to renovate smartly, focusing on quality and functionality.

What's the best way to add storage to a studio apartment?

The best way is with custom-designed, built-in joinery. This allows you to use every available inch of space, especially vertical space. Think floor-to-ceiling wardrobes, beds with integrated drawers, and window seats with hidden storage. This creates a streamlined look and keeps clutter at bay.

How can I make my small apartment look bigger?

Use a light, continuous colour scheme and the same flooring throughout to create flow. Maximise natural light by using sheer curtains. Incorporate large mirrors to reflect light and create an illusion of depth. Choose furniture that is proportionate to the space and has legs to create a sense of openness.

What is a 'turnkey' (chave na mão) renovation?

A 'turnkey' renovation means you hire one company, like Mudelar, to handle the entire project from start to finish. This includes the design, planning, sourcing materials, managing tradespeople, and construction. You are handed the 'key' at the end to a completely finished project, simplifying the process immensely for you.

Can I change the layout of my apartment in Portugal?

Yes, you can change the internal layout by removing non-load-bearing walls, but this is considered a significant alteration. You will need to hire a registered architect to draw up plans and submit them to your local city council (Câmara Municipal) for approval before any work can begin.

Conclusion

Renovating a studio or one-bedroom flat is a powerful way to unlock its full potential. While it requires careful planning and a clear understanding of the costs and processes involved, the end result is a home that is perfectly tailored to your needs and significantly more valuable. From maximizing space with clever design to ensuring the safety and efficiency of hidden systems, every detail matters.
