General information (08)
A general contractor oversees every aspect of a renovation project: studies, supervision, execution of all trades (structural work, fit-out, fine joinery, metalwork, electrical, plumbing, HVAC, finishes) and maintenance. You sign a single contract and deal with a single point of contact. In the prestige segment, it brings together a network of master artisans selected for their craftsmanship and ensures the aesthetic coherence of the completed project.
A shopfitter focuses mainly on the interior fit-out of a point of sale: furniture, display windows, counters, signage. A general contractor like Krapted covers the entire project beyond the fit-out: demolition, structural work, all-trades fit-out, electrical works, plumbing, HVAC, finishes, handover. For the renovation of a prestige boutique in Paris, the general contractor is the brand’s single point of contact.
As a guideline, the renovation of a prestige boutique in Paris typically ranges from €3,500 to €8,000 excl. VAT per sqm, depending on the brief and the level of finish. A signature boutique using noble materials (marble, brass, ebony, leather) will often exceed €6,000 excl. VAT/sqm, while a partial renovation remains around €3,500/sqm. The exact costing depends on the trades involved, the master artisans commissioned and the commercial schedule to be met.
A prestige boutique is delivered in Paris after 3 to 5 months of works, following a 4 to 8-week design and planning phase. A flagship may require 6 to 9 months. A signature restaurant typically takes 5 to 7 months. A palace or boutique hotel requires 9 to 18 months. An ephemeral pop-up is delivered in 6 to 10 weeks.
Krapted supports its clients’ international openings: Paris, Milan, London, Lisbon, New York and Tokyo are among the most frequent destinations. We either deploy our network of French master artisans on site, or coordinate local teams under Paris-based direction. The execution standard remains identical from one capital to the next, with invoicing issued from Paris in euros.
We work at night or during partial closures, with enhanced protection measures (temporary acoustic partitions, HEPA vacuums, dedicated access for trades) and a weekly schedule agreed with the boutique director. This approach extends the project duration by 20 to 40%, but preserves the boutique’s revenue. We recommend it for Paris flagships, whose monthly takings often exceed one million euros.
Our network brings together seven master artisan trades that we find on almost all prestige retail and hospitality projects: workshop joinery, decorative metalwork (bronze, brass, patinated steel), ornamental plaster and staff, marble work, decorative painting (traditional lacquers, faux marble), upholstery, glasswork and mirror-making. No artisan is selected through a tender process: all are chosen on recommendation and after a visit to their workshop.
Our first conversation is a scoping meeting, with no obligation, during which you present your project: brief, floor area, opening schedule, expected level of finish, site constraints. We listen, ask the necessary technical questions, and confirm within the following days our ability to take on the project. If everything is aligned, the design phase begins with an indicative budget estimate within two to four weeks.
The Maison (06)
Yes, we support our clients with their international openings: Paris, Milan, London, Lisbon, New York and Tokyo are among our regular destinations. We either deploy our network of French master artisans on site, or coordinate local teams under Paris-based direction, with the same execution standards everywhere. Our head office remains in Paris, invoicing is in euros, and all administrative coordination is centralized.
Our master artisans are selected for their expertise and the quality of their work. Our network brings together workshop joiners, decorative metalworkers, plaster specialists, decorative painters and marble workers, all recruited on the recommendation of fellow artisans or prestigious clients. For each project, we assemble a bespoke team: an artisan approved on a retail flagship will only join the team for a palace if the brief calls for it, and vice versa.
Krapted is a French general contractor founded in 2026, dedicated to the interior renovation of prestige brands. We bring together a network of French master artisans selected for their craftsmanship, and support our clients with their openings in Paris and internationally. The founder combines several years of experience on major French projects with strategic consulting for CAC40 groups and Private Equity funds.
We support prestige brands with their openings and refurbishments: luxury retail boutiques, fine-dining restaurants, palaces and boutique hotels, foundations and cultural venues, and head offices of major groups. Discretion is part of the agreement: names remain confidential without written consent. We select our clients based on the exacting nature of their brief and the quality of the relationship.
We work in close alignment with the interior architects, scenographers and design offices appointed by the brands. We execute the creative vision without diluting it, while bringing our construction expertise: technical feasibility, selection of master artisans, project sequencing, handover. When a brand does not have a dedicated architect, we can handle the design studies and project management in-house.

Expertise (06)
A general contractor is the client’s single point of contact on a renovation project: it oversees design studies, scheduling, supervision and execution of all trades (structural work, fit-out, fine joinery, metalwork, finishes) as well as maintenance. In the prestige segment, it brings together a network of master artisans selected for their craftsmanship, ensures the aesthetic coherence of the completed project, and aligns with the brands’ commercial calendars.
A shopfitter focuses mainly on furniture and interior layouts for a retail space: joinery, display windows, counters, signage. A general contractor covers the entire project beyond the fit-out: demolition, structural work, all-trades fit-out, electrical works, plumbing, HVAC, finishes, handover. For the renovation of a prestige boutique in Paris, the general contractor is the brand’s single point of contact.
Renovating a prestige boutique in Paris typically takes between 3 and 5 months on site, following a 4 to 8-week design and costing phase. Timelines vary according to the floor area (typically 60 to 400 m²), the level of finish (lacquer, marble, worked metals) and site constraints (Haussmannian arcade, occupied premises, opening during fashion week). A flagship may require 6 to 9 months, while an ephemeral pop-up can be delivered in 6 to 10 weeks.
As a guideline, a high-end flagship retail renovation in Paris ranges from 3 500 to 8 000 € excl. VAT per m², depending on the brief and the level of finish. A signature boutique using noble materials (marble, brass, ebony, leather) will often exceed 6 000 € excl. VAT/m², while a partial renovation remains around 3 500 €/m². The exact costing depends on the trades involved, the master artisans commissioned and the commercial schedule to be met.
Yes, we work in occupied premises on the renovation of prestige boutiques when the brand wishes to keep its point of sale open. The project is then organised in night phases or partial closures, with enhanced protection, dedicated access for trades and a weekly schedule agreed with the boutique director and the Visual Merchandising teams. This approach extends the project duration by 20 to 40%, but preserves the boutique’s revenue.
We directly coordinate the following trades: structural work, fit-out, fine joinery, metalwork, electrical, plumbing, HVAC (heating-ventilation-air conditioning), floor and wall finishes, decorative painting, signage. On prestige retail projects, coordination also includes Visual Merchandising teams and the brands’ approved suppliers. All trades here means genuine in-house integration, rather than subcontracting managed remotely.
Retail (04)
In Paris, the renovation of a prestige boutique typically ranges from €3,500 to €8,000 excl. VAT per m², depending on the brief and the level of finish. A signature boutique using noble materials (marble, brass, ebony, leather) will often exceed €6,000 excl. VAT/m², while a partial renovation remains around €3,500/m². The budget depends on the trades involved, the master artisans commissioned and the constraints of the site: Haussmannian arcade, occupied premises, night-time working hours.
A flagship boutique requires 6 to 9 months of works, following a 4 to 8 week design and planning phase. A standard boutique of 60 to 400 m² is delivered in 3 to 5 months; a temporary pop-up in 6 to 10 weeks. The schedule is aligned with the brand’s commercial calendar: the reopening date is set first, then the project timeline is built backwards, trade by trade.
Yes, a boutique can remain open during its renovation: the project is then carried out at night or with partial closures by zone. This approach, known as working in occupied premises, extends the duration of the works by 20 to 40% but preserves the boutique’s revenue, a frequent trade-off for Parisian flagships whose monthly takings often exceed one million euros. It requires enhanced protection measures and a daily return to full commercial condition.
On a prestige boutique project, the general contractor coordinates the brand’s Visual Merchandising teams at the end of the project: windows, display furniture, product lighting. The required technical provisions (power supplies, fixings, conduits) are incorporated into the design studies from the preliminary phase. This forward planning avoids late drilling and rework on already completed finishes, the main cause of delays in the final two weeks.
Fine dining (04)
A full renovation of a fine-dining restaurant requires 5 to 7 months of works, including the professional kitchen, following a 4 to 8 week design and planning phase. A renovation of the dining room alone, without any work on the kitchen, can be delivered in 2 to 4 months. The timeline depends on the complexity of the technical trades (extraction, utilities, refrigeration), the safety commission review, and the announced opening date, which determines the backward-planned schedule.
A restaurant is subject to three regulatory frameworks: ERP standards (establishment open to the public) for fire safety, escape routes and accessibility; food hygiene regulations for the kitchen, dishwashing area and clean/dirty flows; and acoustic requirements in relation to neighbours for evening operations. Compliance is built in from the preliminary design stage, because any non-compliance discovered at the end of the project can delay the opening permit by several weeks.
Yes, a restaurant can remain partially open during renovation if the work areas can be separated: the dining room refurbished in two phases, the kitchen handled during a short closure, the bar kept in service. Noisy work is scheduled outside lunch and dinner service. This approach extends the project duration by around 20 to 40%, but preserves both clientele and on-site teams. A full closure remains preferable for a major kitchen overhaul.
On a restaurant project, the general contractor orchestrates coordination between the chef and their team (kitchen layout, equipment, service flows), the architect or scenographer (dining room concept, materials) and the trades. A single point of contact arbitrates the interfaces: moving an extraction hood changes a ceiling, widening a pass-through alters a partition. Centralising these decisions prevents overlapping rework that sends budgets and timelines off course.
Hospitality (04)
Renovating a palace or boutique hotel typically takes 9 to 18 months, depending on the number of keys, the scope of the programme (guest rooms only, or rooms and public areas) and the chosen phasing. One floor of 10 to 15 rooms is usually delivered in 3 to 4 months. In occupied premises, the hotel retains part of its capacity throughout the works, which extends the schedule by 20 to 40% but preserves revenue.
A hotel renovation in occupied premises is organised floor by floor: the levels under construction are isolated (dedicated access, reserved service lifts, acoustic partitions), noisy works are confined to time slots agreed with management, and guests are kept away from project traffic. The sample room is approved before rollout. This method preserves operations: the hotel continues to sell the completed floors while the next ones are being transformed.
A sample room is the first renovated room in a hotel refurbishment programme, executed exactly as per the final design: materials, layouts, joinery, lighting, bathroom. Once approved by the client and the architect, it becomes the contractual benchmark for the subsequent floors. It allows fine-tuning of every detail before rolling out at scale, where a single mistake would be multiplied by the number of keys. Its unit cost is higher, but its impact on the final quality is decisive.
Renovating a hotel calls on all trades: demolition, light structural work, plumbing and technical risers, electrical and low-voltage systems, HVAC, bespoke joinery, bathroom marble work, decorative painting, floor and wall finishes, upholstery and glazing. To these are added the packages specific to hospitality: guestroom door ironmongery, signage, bedding and acoustic wall coverings. Coordinating these packages across repetitive floors is at the very heart of the general contractor’s role.
Offices (04)
Renovating an executive floor or reception area in Paris generally ranges from 2 500 to 5 000 € excl. VAT per m², depending on the level of finish and the proportion of bespoke joinery. A standard office floor is typically refurbished for around 1 200 to 2 000 €/m², while prestige areas (boardrooms, executive offices, reception spaces) exceed this range due to the use of noble materials, enhanced acoustic performance and integrated, project-specific furniture.
Yes, office renovation in occupied premises is the most common arrangement: the project progresses floor by floor or half-floor by half-floor, teams are moved through internal rotations (“drawer” moves), and noisy works (drilling, coring, demolition) are concentrated in the evening and at the weekend. This organisation extends the schedule compared with an empty building, but avoids renting temporary space, which is often more expensive than a longer project duration.
A boardroom requires acoustic insulation of around 35 to 45 dB from adjacent spaces to ensure confidentiality of discussions, and a short reverberation time for comfortable meetings and videoconferencing. These performance levels are built in from the design stage: independent double-skin partitions, acoustic doors, sound-absorbing treatment of ceilings and walls, silencers on the ventilation system. A handover measurement at the end of the project confirms the result.
Renovating a head office is typically planned in phases of 2 to 4 months per floor, following a 6 to 10-week design and planning phase. A full executive floor, with boardroom and reception areas, usually requires 3 to 5 months of works. For a multi-floor programme in occupied premises, the overall schedule ranges from 6 to 18 months, depending on possible team rotations and the company’s tolerance for disruption.
Culture (04)
Renovating an art gallery typically requires 2 to 4 months of works; a private foundation or a full exhibition venue calls for 6 to 12 months, depending on the floor area and conservation systems. On top of this, allow a further two to four weeks for climate stabilisation, followed by the hanging period for the artworks, overseen by the registrar. The schedule is planned backwards from the opening date, which is publicly announced and rarely movable.
An exhibition space typically aims for a stable temperature of around 20°C and a relative humidity close to 50%, with slow variations, as well as air filtration and controlled lighting levels in lux for sensitive works (50 lux for works on paper, 200 lux for paintings). These conditions, defined by the collections manager and the insurers, determine the scope of the HVAC package from the design phase and are verified through monitoring before the arrival of the first crates.
Scenographic execution refers to the construction of the physical elements that support an exhibition: partition walls, plinths, display cases, mediation furniture, adjustable lighting, finishes. The scenographer designs; the general contractor executes to the millimetre on approved drawings, integrating electrical provisions and invisible fixings. Quality is judged in raking light and in the way the installation disappears behind the artwork: a successful hanging wall goes unnoticed.
An event venue that remains in operation is renovated between functions: the project is organised into intervention windows, sometimes of just a few days, with prefabricated elements produced in the workshop to reduce installation time on site. Installations are dismantled and protected before each event, then work resumes. This approach calls for meticulous preparation: everything that can be produced off site is, and installation becomes an assembly process.
Leisure (04)
Renovating a high-end spa typically ranges between €4,000 and €9,000 excl. VAT per m², a higher level than retail due to the technical trades involved: waterproofing of wet areas, water and air treatment, hammams and treatment equipment. Close to 70% of the budget goes into works that are invisible at handover. A dry treatment room is usually renovated for around €2,500 to €4,000/m², while wet areas (hammam, pools, experiential showers) account for the highest costs.
A wellness centre combines several regulatory frameworks: public safety rules for establishments open to the public (escape routes, fire-rated materials, accessibility for people with reduced mobility), health requirements specific to the treatments provided (disinfectable surfaces, ventilation, management of clean and soiled flows) and, for pools and hammams, the public health code governing water treatment. These constraints must be addressed from the design phase: late compliance on a waterproofing or ventilation package will require removing newly completed finishes.
A lounge or reception room sees a constant flow of people: materials are chosen for their resistance to wear and their ease of repair. Floors in hard stone, full-body porcelain stoneware or technical textiles rated for heavy traffic; seating with replaceable upholstery; corners and lower walls protected by noble yet robust materials (brass, solid oak, stone). The logic of prestige applies differently here than in retail: beauty must endure into the fifth year, not only on opening day.
A full spa renovation requires 4 to 8 months of works, depending on the floor area and the proportion of wet zones, following a 6 to 10 week design and planning phase. A lounge or VIP salon requires 3 to 6 months in occupied premises, versus 2 to 3 months if it can close. Technical testing (water commissioning, heating up hammams, balancing the ventilation, acoustic measurements) adds a further two to three weeks. In occupied premises, the project is phased by zones to maintain a partial offer.
