In summary
- Design fees range from 15 to 150 €/m² in Spain; construction costs for high-quality projects range from 800 to 1,200 €/m².
- According to the approximate calculation in this guide, a high-end home of 200 m² with all included features ranges from approximately 1,090 to 1,930 €/m².
- In hotels, the budget is calculated per room: €15,300 for FF&E in a boutique hotel and €63,700 in a 5-star hotel.
- Published fees per square meter decrease as the area increases; construction cost ranges do not.
The price per square meter for a luxury interior design project depends on what is being measured. Design studio fees range from €15 to €150 per square meter, according to Cronoshare, and the cost of a high-quality renovation ranges from €800 to €1,200 per square meter, according to Habitissimo (September 2026). These are two different figures, and it’s best not to confuse them when requesting a quote.
The most widely available pricing guides in Spain do not specify a separate category for high-end projects. This guide separates fees from total costs, organizes the ranges by property type and square footage, and includes a detailed breakdown of costs for a 200 m2 high-end home.
How much does a luxury interior design project cost per square meter?
A luxury interior design project costs between 800 and 1,200 €/m² for construction work alone using high-quality materials, according to Habitissimo (2026). When adding fees, permits, home automation, furniture, and contingencies using Studio HC’s percentage rates, this guide’s approximate calculation for a 200-square-meter home ranges from €1,090 to €1,930 per square meter.
| Concept | Published middle section | Published upper section |
|---|---|---|
| Design Fees | 20–40 €/m² (national average, Cronoshare) | 70 €/m² (maximum according to Habitissimo); over 100 €/m² for residential properties and up to 150 €/m² for commercial spaces (Cronoshare) |
| Construction Work | 400–600 €/m² (basic); 750 €/m² (medium) | 800–1,200 €/m² (high-quality) |
| Premium materials or brands | 25% to 50% surcharge |
The fees cover the firm’s work: concept, layout, technical documentation, selection of materials, and—if contracted—construction supervision. The total cost includes construction, utilities, furniture, permits, and contingencies. The averages provided by comparison sites are based on requests from private individuals and do not break down projects by price range: Zaask estimates the national average price for an interior design project at €750. In Studio HC’s example of a 200 m² villa, the fees (€8,000–13,000) are a fraction of the interior renovation cost (€160,000–240,000).
How Interior Design Firms Charge: Per Square Meter, Percentage of Construction Costs, Flat Fee, or Hourly Rate
Interior design firms charge by square meter, as a percentage of the construction cost, with a flat fee, by the hour, or through a turnkey package that combines design and execution. The model chosen determines what is included in the price and how it varies if the scope of the project changes.
| Billing Model | Market Range | When It's a Good Fit |
|---|---|---|
| Per square meter | 15–150 €/m² (Cronoshare) | Clear scope and defined area |
| Percentage of project cost | 5–10% (Cronoshare, Zaask); 8–15% (ToBe Studio) | Comprehensive renovations and new construction |
| Fixed fee | From €300 to over €15,000 (Cronoshare) | Clearly defined phases and deliverables |
| By the hour | €25–150/hr (Cronoshare) | One-time consulting services |
| Turnkey | Starting at €600/m² all-inclusive, mid-range in Madrid (ToBe Studio) | Clients who want a single point of contact |
There is no single figure for the percentage charged for construction work: Habitissimo mentions a range of 20–25% of the total construction cost. ToBe Studio applies its 8–15% rate to comprehensive design services, and other sources do not always clarify which phases each percentage covers. Before comparing quotes, the client needs to know the basis on which each percentage is calculated.
Price Range by Project Type
The price range varies by project type, and the unit of measurement changes accordingly: residential and retail projects are calculated per square meter, while hotels are calculated per room. The published figures range from €800–1,200 per square meter for high-end residential projects to €63,700 per room for a 5-star hotel.
| Typology | Reference Range |
|---|---|
| High-end housing | €800–1,200 per square meter of construction |
| Commercial space | €15–150/m² in design fees |
| Boutique hotel | €15,300 in FF&E per room |
| 5-star hotel | €63,700 in FF&E per room |
| Restoration | No reliable public reference; quotes provided on a case-by-case basis |
High-end housing
A high-end home starts at a construction cost of 800 to 1,200 €/m2, a range that Habitissimo publishes for high-quality projects and that Studio HC applies to a 200 m2 villa. Where a project falls within this range depends on the extent of the layout redesign, the proportion of custom woodwork, and the materials used. Studio HC estimates that choosing premium materials or brands adds between 25% and 50% to the budget. Learn more about the scope of this interior design service.
Jewelry and Watch Boutiques
There is no specific Spanish public reference for the interior design of a jewelry or watch boutique. Price guides in Spain group these spaces together with other retail spaces: Cronoshare estimates design fees for a retail space at between 15 and 150 €/m2, and Habitissimo indicates that they rarely fall below 30 €/m² and can exceed 150 €/m². Items specific to a jewelry store—such as security display cases, lighting for gemstones and metals, access control, or the requirements outlined in each watch brand’s brand manual—are not quantified in any of the public sources consulted; therefore, their impact on the budget depends on each individual project.

Hotels
Cost estimates for hotel interior design are expressed per room. According to UDL Logistics’ FF&E Hospitality Guide for Spain and Portugal (May 2026), FF&E (furniture, lighting, textiles, decor, and in-room technology) costs €15,300 per room in a boutique hotel, €20,100 in a 4-star city hotel, and €63,700 in a 5-star luxury hotel. These figures do not include civil engineering or utilities. In new-construction hotels, the master plan defines the layout of common areas and guest rooms prior to interior design.
Restaurants
There is no established price per square meter of public space for the interior design of a high-end restaurant in Spain; price comparison sites group it together with commercial spaces and offices. A restaurant includes elements that do not exist in a residential home, such as a professional kitchen or a ventilation system, and none of the public sources consulted provide figures for these. For this reason, the budget for a high-end restaurant is based on a specific preliminary design rather than a rate per square meter.
Price Range by Area: How the Price per Square Meter Varies
The price range by square footage shows that interior design fees per square meter decrease as the square footage increases, according to the published guidelines. According to Zaask, a project ranging from 1 to 50 m² is charged at 30–40 €/m², and one ranging from 51 to 100 m² is charged at 20–30 €/m².
| Area | Total Fees (Cronoshare, 2026) | Total fees (Studio HC, 2026) |
|---|---|---|
| 50–70 m² | 1,500–5,600 € | 900–2,000 € (50 m²) |
| 70–120 m² | 2,100–9,600 € | 2,000–4,000 € (100 m²) |
| 120–150 m² | 3,600–12,000 € | 3,000–6,000 € (150 m²) |
| 200 m² | No data available | 8,000–13,000 € (house) |
The published price ranges do not follow that logic. Habitissimo gives the same range of 800–1,200 €/m² for high-quality finishes without distinguishing between floor areas, and Studio HC applies this range as-is to its example of a 200-square-meter villa, estimating an interior renovation cost of 160,000 to 240,000 euros.
Which expenses drive up the cost per square meter in high-end interior design?
The items that drive up the cost per square meter in high-end interior design, according to the percentages published by Studio HC (2026), are premium materials or brands—which add 25% to 50% to the cost—furniture and decor, home automation, and the contingency fund, which are calculated as a percentage of the budget.
- Premium materials: natural stone, hardwoods, and treated metals, with a 25% to 50% surcharge (Studio HC).
- Furniture and decor: between 15% and 30% of the budget (Studio HC). See the " Furniture" section for more details.
- Home automation: between 5% and 8% of the budget (Studio HC).
- Contingencies: a reserve of 10% to 15%, with special attention given to older homes (Studio HC).
- Licenses and fees: between 2,500 and 5,000 euros for the example of a 200-square-meter villa (Studio HC).
Sample Estimated Budget for a 200 m2 High-End Home
A rough estimate for a high-end home of 200 m² ranges from 218,500 to 385,200 euros, or between approximately 1,090 and 1,930 euros per square meter. This calculation, developed specifically for this guide, combines construction costs, professional fees, permits, home automation, furnishings, and contingencies, using the ranges provided by Habitissimo and Studio HC (2026).
| Line Item | Calculation basis | Minimum | Maximum |
|---|---|---|---|
| High-Quality Construction | 200 m² × 800–1,200 €/m² | 160,000 € | 240,000 € |
| Interior Design Fees | Example of a villa (Studio HC) | 8,000 € | €13,000 |
| Licenses and Fees | Example of a villa (Studio HC) | €2,500 | 5,000 € |
| Home Automation | 5–8% of the project cost | 8,000 € | €19,200 |
| Furniture and Decor | 15–30% of the project cost | 24,000 € | €72,000 |
| Contingencies | 10–15% of the project cost | €16,000 | €36,000 |
| Total | 218,500 € | 385,200 € |
Construction costs are the item that has the greatest impact on the total cost, ranging from a minimum of 80,000 euros to a maximum of 80,000 euros, followed by furniture, at 48,000 euros. The calculation applies the percentages to construction costs and excludes outdoor areas and the pool.
Note: These are approximate figures based on sources published in 2026. The final price depends on the condition of the property, its location, the materials used, and the scope of the project.
What's Included in a Turnkey Interior Design Project
A turnkey interior design project includes conceptual design, technical plans, permits, construction supervision, furniture production, and delivery of the finished space—all through a single point of contact. That is why the price per square meter covers both design and execution and cannot be compared to isolated fees.
- Preliminary design and concept: requirements specification, layout, and aesthetic direction.
- Technical design: plans, measurements, specifications, lighting, and custom furniture.
- Licenses: building permits and, for business premises, business operation permits.
- Construction Management: Quality Control, Deadlines, and Trades.
- Furniture, Fixtures, and Equipment (FF&E): manufacturing, procurement, logistics, and installation.
- Delivery: final review, styling, and documentation.
If only the design phase is contracted, technical assistance costs between 2 and 4 €/m² and construction management costs an additional 4 to 6 €/m² in the average residential market, according to Cronoshare. Comprehensive project management brings these phases together under a single point of contact. UJO+Partners works with this model from the preliminary design phase through to project handover.

Frequently Asked Questions
Can I hire someone for the interior design project without also hiring a project manager?
Yes, you can hire an interior design firm without construction supervision: the firm provides the technical documentation, and the construction company handles the actual work. Cronoshare estimates that adding construction supervision costs an additional 4 to 6 €/m2. In that case, coordination between the design and the construction falls to the client or the contractor.
How much should you set aside for unforeseen expenses in an interior design project?
An interior design project involving construction work should set aside between 10% and 15% of the budget for unforeseen expenses, according to Studio HC (2026). For a project costing 200,000 euros, that contingency fund amounts to between 20,000 and 30,000 euros. Studio HC warns that surprises always arise in older homes and considers it essential to completely renovate the plumbing and electrical systems.
Why is interior design more expensive in Madrid and Barcelona?
Interior design costs more in Madrid and Barcelona than in other Spanish cities, according to the examples published. Zaask compares a 15,000-euro project in Madrid or Barcelona with a similar one costing about 4,000 euros in Palma or Córdoba. Cora Arquitectura points out that in neighborhoods such as Salamanca, Chamberí, or the historic center, buildings have unique architectural features that require customized solutions and drive up the average price.
