Your commercial project in expert hands
Opening a restaurant, designing a boutique, transforming a space into a hotel: each commercial project in Paris requires specific expertise. Between safety standards, accessibility constraints and brand identity creation, challenges are numerous.
Hauss Paris connects you with architects and interior designers specialized in commercial design. Retail design, hospitality, restaurants: our network includes professionals experienced in each sector.
Whether you're an entrepreneur, franchisee, investor or professional, we find the right architect for your project.
Why hire a specialized retail architect?
Commercial design cannot be improvised. Beyond aesthetics, it's about creating a space that complies with regulations, is functional for your activity and attractive to your customers.
In Paris, every public establishment (ERP) must meet strict standards: fire safety, accessibility, kitchen extraction, sound insulation. A specialized architect knows these constraints and designs a compliant project from the start.
A well-designed business generates more revenue. Layout influences customer flow, product presentation, time spent on premises.
Restaurants and cafés in Paris
From neighborhood bistro to gastronomic restaurant, our architects design spaces that tell a story. They master restaurant-specific constraints: kitchen/dining flow, extraction, hygiene standards, acoustics.
Each restaurant project is unique: culinary concept, desired ambiance, number of seats, type of cuisine. The architect adapts the space to your vision while respecting strict ERP standards.
From intimate 30 m² coffee shops to 150-seat restaurants, we support all formats. The goal: create a place where your customers will want to return.
Retail shops and stores
Designing a shop is not just about installing furniture. It's about creating a customer journey, showcasing your products, expressing your brand identity. Our retail architects master these challenges.
From independent concept stores to international franchises, each shop has its constraints: attractive storefront, optimized storage areas, comfortable fitting rooms, lighting that enhances products.
We work with fashion boutiques, concept stores, decoration shops, bookstores. The goal: turn visits into sales, create a memorable experience.
Hotels and hospitality spaces
Creating or renovating a hotel requires specific expertise: strict regulations, specific safety standards, surface optimization per room, creating varied ambiances. Our specialized architects master these constraints.
From budget hotels to boutique hotels, each category has its standards: minimum surface per room, mandatory equipment, accessibility, acoustic comfort. The architect designs compliant and attractive spaces.
Beyond rooms, common areas make the difference: welcoming lobby, bright breakfast room, cozy bar. We create hotels where travelers feel at home.
Medical and paramedical offices
A medical, dental or paramedical office must meet strict hygiene standards, offer confidentiality and comfort to patients, optimize the care pathway. Our architects know these requirements.
Each specialty has its needs: sterilization room for dentists, separate waiting area for general practitioners, physiotherapy space with accessibility. The architect adapts the layout to your practice.
Ambiance matters too: a welcoming medical office reassures patients, improves their experience, reflects your professionalism. We create care spaces that are both functional and calming.
Offices and coworking spaces
Workspaces are evolving: fewer closed offices, more collaborative zones, need for flexibility. Our architects design modern offices, adapted to new ways of working.
Good office design improves productivity, fosters collaboration, attracts talent. Open space, meeting rooms, breakout areas, phone booths: everything is designed for team well-being.
From small consulting firms to large coworking spaces, we adapt the layout to your company culture and operational needs.
Showrooms and event spaces
Showrooms, pop-up stores, event spaces: these ephemeral or permanent venues must leave a lasting impression. Our architects create scenographic spaces that showcase your products or brand.
Flexibility is key: modular furniture, adjustable lighting, removable partitions. The space must be able to evolve according to collections, events, seasons.
From automotive showrooms to luxury pop-up stores, we design spaces that create events and strengthen your brand image.
ERP norms and regulations
All Parisian businesses are ERP (Public Access Establishments) and must comply with strict standards: fire safety (emergency exits, extinguishers, safety lighting), accessibility (ramps, elevators, adapted toilets), ventilation (extraction for professional kitchens).
These standards are not optional: before any opening, the town hall and safety commission inspect the premises. If the project is not compliant, opening is refused. An experienced architect integrates these constraints from the design stage.
Beyond compliance, a good architect transforms constraints into assets: an emergency exit can become a terrace, an accessibility ramp a design element. We design spaces that are both compliant and beautiful.
Turnkey project management
Opening a business is already an entrepreneurial challenge. You don't have time to chase contractors, manage delays, validate a thousand technical details. That's why we offer complete project management.
The architect becomes your conductor: they coordinate all trades (electrician, plumber, carpenter, painter), manage the schedule, control quality, solve unforeseen issues. You validate major decisions, they handle execution.
Result: your business opens on schedule, within budget, compliant with standards. You focus on your business, the architect handles the rest.
Commercial architecture in Paris and Île-de-France
Paris and its region concentrate unique commercial density: each neighborhood has its identity, codes, expectations. From trendy Marais to chic Champs-Élysées, from creative 11th to bourgeois 16th, the architect adapts the project to the territory.
Our network covers Paris city center and all of Île-de-France: Neuilly, Boulogne, Levallois for business districts, Montreuil and Saint-Denis for creatives, Versailles and Saint-Germain-en-Laye for upscale residential.
Whether you're opening a business in the city center or suburbs, we find the architect who knows your sector, understands your target clientele, masters local constraints.

Frequently asked questions
- How long does it take to fit out a commercial space in Paris?
- Allow 2 to 3 months for a simple project (refresh, light boutique), 4 to 6 months for a restaurant or major restructuring, 6 to 12 months for a hotel. Timeframes include design, administrative procedures and construction.
- Can you support me before finding the space?
- Yes. The architect can accompany you during space visits to evaluate potential: technical feasibility, construction estimate, hidden constraints. This pre-purchase consultation service avoids bad surprises.
- I don't own the walls. Is that a problem?
- No. Most commercial spaces are leased. The architect designs a fit-out adapted to your lease: work authorized by owner, recoverable elements at lease end, etc.
- Do you handle administrative procedures (ERP, licenses)?
- Yes, it's included in the architect's mission. They compile files, submit applications and represent you to administrations if necessary.
- I'm opening a franchise. Can you adapt the concept to the space?
- Absolutely. The architect respects the franchisor's specifications while adapting to Paris space constraints. They dialogue with the brand to validate necessary adaptations.
- I'm an investor and not on site. How does it work?
- We're used to supporting investors who cannot be present at every step. The architect manages the project autonomously, keeps you informed via videoconference and reports, and solicits you only for key validations.
- What's the minimum budget for a commercial fit-out project?
- Below 30,000 € of construction, an architect's involvement is rarely economically justified. For smaller projects, we can refer you to a one-time consultation service.
- Do you work outside Paris?
- Yes. Our network covers Paris and all Île-de-France: Boulogne, Neuilly, Saint-Germain-en-Laye, Versailles, and departments 92, 93, 94, 78, 91, 77, 95.
