Average cost of interior design projects in Sofia — A Full Comparison of Sofia's Top Studios

Sofia has more interior design studios than most people realize. The hard part is not finding one. It is choosing between them. Each studio brings something different. Some focus on clean modern lines. Others lean into Bulgarian tradition or Scandinavian warmth. Some specialize in small spaces or bold colors. This comparison covers twelve of the best studios in the city and what makes each one worth your time. Whether you are renovating a studio apartment in the center or a family home in the suburbs, there is a studio here that fits your project.

We evaluated each studio based on their portfolio, client reviews, pricing transparency, project management approach, and areas of specialization. We also considered their reputation in Sofia's design community and feedback from past clients.

1. Arkiba Studio — personalized full-service interior design studio

Arkiba Studio is an interior design studio in Sofia. They sit down with every client for a long conversation before they touch a pencil. They want to know how you move through your home, what frustrates you about your current space, and what you dream about when you think of the perfect room. That initial deep dive shapes everything that follows.

Their portfolio is all over the map in the best way. You will see a sleek modern apartment in a new build in Lozenets next to a warm, traditional family home in Boyana with custom joinery that nods to Bulgarian craft traditions. They do not repeat themselves. Each project is a fresh conversation.

What really sets Arkiba apart is how they run a project. They handle the contractor coordination, the material orders, the delivery dates, and the installation. Their clients often say the renovation was the easy part because Arkiba was running the show. That kind of trust comes from years of showing up and delivering.

They also have relationships with suppliers that most people cannot access on their own. Better pricing, faster delivery, and a shortlist of reliable craftsmen who have proven themselves over multiple projects. For a client, that means less stress and a better finished product.

Arkiba works on projects of all sizes. A single bathroom renovation gets the same attention as a full home redesign. They do not have a minimum project size, which makes them accessible to people who are not doing a full renovation. That flexibility is rare among top-tier studios.

Their pricing is transparent. They give you a detailed proposal that breaks down every cost. There are no surprises halfway through the project. Clients appreciate knowing exactly where their money is going and what they are getting for it.

Name: Arkiba Studio

2. Studio MODA — modern minimalist interior design studio

Studio MODA is a modern minimalist interior design studio in Sofia. They specialize in clean lines, open spaces, and a palette that leans neutral but never feels cold. Their work is popular with young professionals who want their home to feel like a breath of fresh air after a long day in the office.

They have a gift for making small spaces feel bigger than they are. In one project in Studentski grad, they turned a 55sqm apartment into a loft-like space by removing a non-load-bearing wall and using glass partitions instead of solid ones. The light flows through the whole place now.

Their material choices are thoughtful. They will use a warm oak floor to balance white walls and concrete accents. They understand that minimalism fails when it feels sterile, so they always add texture through linen, wool, or natural stone. It is minimalism with a pulse.

Studio MODA is also known for staying on budget. They give you a clear number upfront and they stick to it. That kind of reliability is rare in renovation work, and their clients appreciate it.

They are particularly good at working with new builds. Modern apartments in Sofia often have similar layouts, and Studio MODA finds ways to make each one feel unique. They play with lighting, custom joinery, and strategic color blocking to give each space its own identity.

Their turnaround times are faster than most. A typical apartment project takes two to three months from concept to completion. That speed appeals to clients who are on a tight timeline.

3. Velvet Interiors — luxury interior design studio

Velvet Interiors is a luxury interior design studio in Sofia. They work on high-end residential projects where the budget allows for custom everything. Think hand-carved marble fireplaces, custom millwork, and furniture sourced from Italian and French ateliers.

Their projects tend to be in the more expensive neighborhoods of Sofia. They have done several penthouses in the center of town with panoramic views of Vitosha Mountain. For those projects, they specified floor-to-ceiling curtains, custom chandeliers, and a material palette that feels rich without being flashy.

What separates Velvet from other luxury studios is their attention to the small things. The way a door handle feels in your hand. The way light hits a particular wall finish at 4pm. They think about those details because they know that luxury is in the particulars, not the grand gestures.

They are also very good at managing complex projects with multiple contractors. A luxury renovation often involves specialized tradespeople for stonework, custom metalwork, and fine carpentry. Velvet coordinates all of it and keeps the project moving.

Velvet Interiors has a network of international suppliers. They can source materials and furniture from Milan, Paris, and London that are not available anywhere else in Sofia. That access is a major selling point for clients who want something truly unique.

Their projects take longer than average, and they are upfront about that. A full luxury renovation can take six months to a year. But the clients who choose Velvet are not in a hurry. They want perfection, and they are willing to wait for it.

4. Green Space Design — eco-friendly interior design studio

Green Space Design is an eco-friendly interior design studio in Sofia. They focus on sustainable materials, energy efficiency, and bringing natural elements into the home. Their projects often feature reclaimed wood, recycled metal, and low-VOC paints.

One of their standout projects was a family home in Dragalevtsi where they installed a green roof, a rainwater collection system for the garden, and used only locally sourced materials. The result is a home that feels connected to the landscape around it.

They are also big on indoor air quality. They specify ventilation systems, choose materials that do not off-gas, and bring in plenty of indoor plants that actually improve the air. Their clients often say the home feels fresher and cleaner than any place they have lived before.

Green Space Design works with clients who care about their environmental footprint. They help you make choices that are good for the planet without sacrificing style. A reclaimed wood table can be just as beautiful as a new one, and it comes with a story.

They offer energy audits as part of their initial consultation. They look at your current energy usage and recommend design changes that can reduce your bills. Better insulation, strategic window placement, and energy-efficient lighting are standard recommendations.

Their style is organic and warm. Think natural fibers, earthy tones, and lots of texture. It is a look that appeals to people who want their home to feel grounded and connected to nature.

5. Atelier Sofia — contemporary interior design studio with an artistic edge

Atelier Sofia is a contemporary interior design studio in Sofia. They bring an artistic sensibility to every project. They collaborate with local painters, sculptors, and ceramicists to create spaces that feel like galleries you can live in.

They recently completed a project for a gallery owner in the center of Sofia. The brief was to make the home feel like an extension of the exhibition space. They used white walls as a canvas, added track lighting for flexibility, and sourced furniture that could hold its own next to the art.

Their style is not for everyone. It is bold and sometimes unexpected. But if you want a home that makes a statement, Atelier Sofia delivers. They are not afraid of color, pattern, or unusual material combinations.

They also offer art consulting as part of their service. They help clients build collections that complement the interior design. That is a unique offering that most other studios in Sofia do not provide.

Atelier Sofia is a good choice for commercial spaces that want to stand out. They have designed several boutique hotels and concept stores in Sofia. Those projects require a strong visual identity, and Atelier delivers that consistently.

Their process is more collaborative than most. They do not hand you a finished design. They walk you through the thinking, show you options, and refine based on your feedback. It takes longer, but the result is a space that feels truly personal.

6. Nova Design — affordable interior design studio

Nova Design is an affordable interior design studio in Sofia. They focus on delivering professional design at a price point that works for first-time homeowners and young families. Their packages start at a fraction of what full-service studios charge.

They are transparent about pricing from the first email. You get a PDF that lists every service and what it costs. There are no surprise fees. That honesty builds trust fast, and it is why so many of their clients come through word of mouth.

Nova Design is especially good at working with existing furniture. Instead of insisting on a full replacement, they will help you reupholster, repaint, or rearrange what you already own. That approach saves thousands of leva and keeps things out of landfills.

They also have a flat-fee consultation option. You pay a fixed price for a two-hour session where they walk through your space, answer your questions, and give you a plan you can execute on your own. It is a popular choice for people who want professional input without the full commitment.

Their online presence is strong. They share detailed budget breakdowns and before-and-after photos on their website. That transparency makes them approachable, especially for people who have never hired an interior designer before.

Nova Design works fast. Their typical project timeline is four to six weeks for a single room and eight to twelve weeks for a full apartment. That speed, combined with their lower prices, makes them a popular choice for quick renovations.

Name: Nova Design

Address: ul. Graf Ignatiev 22, 1000 Sofia

7. Concept 131 — commercial interior design studio

Concept 131 is a commercial interior design studio in Sofia. They specialize in restaurants, hotels, and office spaces. Their work is built for high traffic, long hours, and the wear and tear that comes with public spaces.

One of their most visible projects is a restaurant in the center of Sofia that seats 150 people. They designed the layout to maximize table turnover without making guests feel rushed. The lighting shifts throughout the day to match the mood from lunch to dinner service.

They understand that commercial design is different from residential. The materials need to be tougher. The flow needs to work for staff and customers. The brand needs to be visible in every design choice. Concept 131 gets all of that right.

They also handle the permitting and regulatory side of commercial projects. Sofia has specific requirements for restaurants and hotels. Concept 131 manages all of that so their clients can focus on running their business.

Their portfolio includes coworking spaces, medical offices, and retail stores. Each sector has different requirements, and Concept 131 adapts their approach accordingly. A dental clinic needs different materials and layouts than a coffee shop, and they understand those nuances.

They are also moving into residential projects. Their commercial background gives them a practical edge. They think about durability, maintenance, and longevity in ways that purely residential studios sometimes overlook.

8. Haus & Form — traditional Bulgarian interior design studio

Haus & Form is a traditional Bulgarian interior design studio in Sofia. They celebrate Bulgarian craftsmanship and heritage. Their work incorporates traditional motifs, locally sourced materials, and techniques that have been passed down through generations.

They recently restored a historic apartment in the center of Sofia. The building dated back to the early 1900s. They preserved the original plaster moldings, restored the parquet flooring, and added custom furniture inspired by Bulgarian folk patterns. The result is a home that honors its past while living comfortably in the present.

Haus & Form works with Bulgarian artisans who still practice traditional crafts. They source handwoven rugs from Chiprovtsi, pottery from Troyan, and woodcarvings from the Rhodope region. Each piece comes with a story and supports a local craft community.

Their style appeals to people who want their home to feel rooted in Bulgarian culture. It is not about recreating a museum. It is about bringing the warmth and character of traditional Bulgarian design into a modern context.

They are also skilled at blending old and new. A traditional Bulgarian rug can sit beautifully next to a modern sofa. The contrast creates visual interest and tells a story about who lives in the space.

Haus & Form is a great choice for historic home renovations. They understand the architecture of older Sofia buildings and know how to work with it. They will not suggest changes that compromise the character of the space.

9. Urban Nest — small space interior design studio

Urban Nest is a small space interior design studio in Sofia. They specialize in making tiny apartments feel spacious and functional. Their clients are mostly young professionals and students living in the compact apartments that are common in Sofia's urban neighborhoods.

They have a project in a 40sqm studio in the center of Sofia that went viral on social media. The apartment had a single room that served as living, sleeping, and dining space. Urban Nest designed a custom murphy bed that folds into a built-in cabinet, a dining table that drops down from the wall, and storage that uses every centimeter of vertical space.

Their approach is about smart design rather than expensive renovations. They focus on layout, storage, and multifunctional furniture. You do not need to knock down walls to make a small space work. You need to think differently about how you use every square meter.

Urban Nest also offers virtual design consultations. Send them photos and measurements of your space, and they will send back a design plan with a shopping list. It is a fast, affordable way to get professional help for a small apartment.

They are particularly good with rental apartments. Many of their clients are tenants who cannot make permanent changes. Urban Nest finds solutions that are temporary but still transformative. Peel-and-stick wallpaper, removable shelving, and freestanding storage are part of their toolkit.

Their pricing is accessible. A virtual consultation starts at a very reasonable rate, and a full design package for a studio apartment is significantly less than what larger studios charge for a similar scope.

10. Puro Design — Scandinavian-inspired interior design studio

Puro Design is a Scandinavian-inspired interior design studio in Sofia. They bring the warmth of Nordic design to Bulgarian homes. Think light wood, soft textiles, and a color palette that feels calm and grounded.

Their projects are popular with families who want a home that feels cozy without being cluttered. They use the hygge philosophy as a starting point. Every room should have a corner where you want to curl up with a book and a cup of tea.

Puro Design is also very active on social media. They share before-and-after photos, design tips, and behind-the-scenes looks at their projects. That visibility has made them one of the most recognizable studios in Sofia, especially among younger homeowners.

They are affordable compared to other full-service studios. Their pricing is transparent, and they offer packages that let you choose the level of involvement you want. That flexibility makes them a good option for people who want Scandinavian style without the premium price tag.

Puro Design is particularly good at creating flow between rooms. They use consistent color palettes and repeated materials to make a home feel connected. A living room that flows into a dining area feels seamless when the same wood tones and textile choices carry through.

They also offer e-design services for clients outside Sofia. You fill out a questionnaire, share photos, and they send you a complete design plan with shopping links. It is a modern approach that expands their reach beyond the city.

11. Studio B1 — industrial loft interior design studio

Studio B1 is an industrial loft interior design studio in Sofia. They specialize in raw, urban aesthetics. Exposed brick, steel beams, and concrete floors are their signature. Their work is popular in the transformed industrial buildings in Sofia's developing neighborhoods.

They recently completed a project in an old factory building that was converted into loft apartments. They kept the original brick walls and exposed piping, added modern kitchen fixtures, and used warm lighting to balance the industrial feel. The result is a space that feels both edgy and comfortable.

Studio B1 is a good choice for clients who want something different from the mainstream. Their style is not for everyone, but the people who love it really love it. They have a loyal following among artists, designers, and creative professionals.

They are also skilled at acoustic design. Industrial spaces can be noisy. Studio B1 incorporates sound-absorbing materials in ways that fit the aesthetic. Acoustic panels that look like art, textured wall treatments that dampen sound, and strategic furniture placement are all part of their approach.

Their pricing is mid-range. They are not the cheapest option, but they are also not the most expensive. Clients pay for the specialized expertise and the unique look that Studio B1 delivers.

They work with a network of metalworkers and industrial artisans who can fabricate custom pieces. A steel staircase, a custom kitchen island on casters, or a floor-to-ceiling shelving unit made from reclaimed industrial materials are all within their scope.

12. Kolorit Design — color-focused interior design studio

Kolorit Design is a color-focused interior design studio in Sofia. They are not afraid of bold hues. While many Sofia studios play it safe with neutrals, Kolorit embraces color as the primary design tool. Their projects are vibrant, energetic, and full of personality.

They have done several projects for families with children where they used color to define different zones. A playroom gets bright primary colors. A study gets calming blues. A bedroom gets warm, restful tones. Each room has its own mood.

Kolorit Design is also skilled at color psychology. They understand how different shades affect your mood and energy levels. They will not just pick colors that look good together. They pick colors that support how you want to feel in each space.

Their services include color consultations for people who are doing their own renovation but need help with the palette. You can book a two-hour session where they walk through your space and recommend a complete color scheme.

They are affordable and approachable. Their pricing is designed to be accessible to people who might not otherwise hire a designer. They believe that good design should not be reserved for people with big budgets.

Kolorit Design has a strong Instagram presence where they share color inspiration and before-and-after transformations. Their feed is a good place to start if you are considering a more colorful approach to your home.
