How Much Does an Interior Designer Cost to Renovate a Home in 2025: Real Prices and What Changes with Restylit

How Much Does an Interior Designer Cost to Renovate a Home in 2025: Real Prices and What Changes with Restylit


How much does an interior designer cost to renovate a home? In Italy prices range from €50 to €150 per hour for an hourly consultation, from €3,500 to €8,000 for a complete project with a physical studio on a 70-80sqm apartment, and from €33 to €55 per sqm for an online executive project with Restylit. The price difference between online and offline does not depend on the quality of the project (or at least it shouldn't) — it depends almost always on the studio's operating costs, which in the online model simply don't exist and are not passed on to the client. In short: an online interior design project costs on average 60-70% less than a traditional physical studio, with half the timeline and no significant differences in quality for the vast majority of residential renovations.


What you'll find in this guide. Real market prices line by line, an honest comparison between available formats (hourly consultation, physical studio, online), when it makes sense to spend more and when it doesn't, the difference between an interior design project and site supervision, and the questions to ask before signing any quote. If you're renovating and don't know where to start on the design side, this is the right place.


Why Prices Vary So Much

The first thing you notice when searching "interior designer prices" is the enormous variation. From €200 to €25,000 per project — quite a range. How is that possible, you might wonder.

Because you're comparing very different things. The factors that determine the final price are essentially these.

The type of intervention. A colour consultation is different from a layout project. A project with 3D renderings is different from an executive project with technical drawings for the contractor. Each level of depth has a different cost.

Online vs physical studio. A physical studio has high fixed costs: rent, staff, site visits, travel. These costs are passed on in the fee. An online service has much lower operating costs. That difference goes to the client.

Project complexity. A 35sqm studio with a simple layout is not as complex as a 120sqm apartment with a full renovation and relocated plumbing.

Geographic location. An interior designer in Milan costs 20-30% more than the national average. In Rome about 15-20% more. In Southern Italy you can find prices 15-20% below the national average.

The brand. Yes, there are great architects who have thoroughly earned their reputation and the possibility of charging substantial fees for their projects.


Available Formats and Market Prices in 2025

Hourly consultation — physical studio

The most traditional format. The interior designer comes to your home, carries out a site visit, and gives advice on materials, layout and furniture.

Average rate: €50-150 per hour Project minimums: €500-1,000 even for small interventions What it includes: site visit, in-person consultation, verbal or written guidance When it makes sense: for specific questions about an existing space, not for a full renovation

Complete project — physical studio

Site visit, complete project with drawings and renderings, often with site supervision.

Average rate: €80-200 per sqm for standard apartments For an 80sqm apartment: €3,500-8,000 for the project alone, works not included Timeline: 2-6 months from first meeting to delivery When it makes sense: complex renovations, those who want continuous physical presence, those with no budget or time constraints

Online consultation — per-room packages

The intermediate format, which has grown significantly in recent years. Everything happens remotely via video calls and renderings — guaranteeing, once you find the right partner, an extremely satisfying result.

Average market rate: €200-600 per room Typically includes: moodboard, 3D renderings, shopping list, video call When it makes sense: furnishing one or two rooms from scratch, restyling without renovation

Online executive project — Restylit Essential and Advanced

The format for those who are renovating and need the complete project: from layout to technical drawings to hand over to the contractor.

Essential — €33/sqm (minimum 100sqm) Complete design for renovations. Includes 3 video calls, 3D renderings with 2 revision rounds, up to 4 executive technical drawings, complete shopping list. Delivered in approximately 60 days.

Advanced — €55/sqm (minimum 100sqm) The most comprehensive service. 5 video calls, renderings with 3 revision rounds, up to 8 technical drawings, cost estimate, remote artistic direction. For complete renovations where nothing can be left to chance.

Concrete example: 100sqm apartment with Restylit Essential → €3,300 for the complete project with renderings, technical drawings and shopping list. The same project with a physical studio in Milan: €8,000-20,000.


Summary Table: Prices 2025

Format Indicative price Average timeline Best for
Hourly consultation (physical) €50-150/hour Variable Questions about existing space
Complete project (physical) €80-200/sqm 2-6 months Those who want physical presence
Per-room package (online) €200-600/room 2-4 weeks Furnishing a single room
Essential Restylit €33/sqm ~60 days Full renovation
Advanced Restylit €55/sqm ~60-70 days Renovation where nothing can go wrong

In summary on prices: an online interior design project costs on average 60-70% less than a traditional physical studio. On a 100sqm apartment the difference is concrete: €3,300 with Restylit Essential versus €8,000-20,000 with a Milan studio. With half the timeline. And no significant differences in project quality for the vast majority of residential renovations.


What Happens If You Don't Hire an Interior Designer

This is the question nobody asks explicitly enough. So I'll ask it.

Those who renovate without an interior design project almost always find themselves in the same situation: the building work finishes, it's time to choose materials and furniture, and that's where the problems begin. The floor that looked perfect in the sample but mounted across 80sqm feels cold. The kitchen that doesn't align with the plumbing connections. The sofa that doesn't scale with the space. The bathroom tiles ordered short, the site at a standstill waiting for a reorder that might not match the original batch.

These aren't stupid mistakes. They're structural errors that come from the absence of an overall vision before any work begins.

The average cost of recoverable mistakes in a renovation without a project ranges between €1,500 and €4,000. Often more, when it comes to choices like flooring or wall finishes that stay for twenty years even when they stop feeling right or start to tire quickly.

A Restylit Essential project on 100sqm costs €3,300.


The Difference That Matters: Online vs Physical at Equal Quality

This is the point many traditional studios focus their communication on: "online can't be the same as physical presence." Nothing could be further from the truth.

That said, in some very specific cases it's true. Sites with complex structural issues, historic buildings with particular constraints, those who need someone in the site every week to supervise. In these cases a local physical professional is the right choice.

For the vast majority of residential projects, the real difference is almost eliminated by the quality of digital tools available today. 95% of the information needed to design a space well comes from a floor plan, photos and a video call conducted properly.

What changes significantly is the price.

A 100sqm apartment with a physical studio in Milan: €8,000-20,000 for the project alone. The same apartment with Restylit Advanced: €5,500.

Same quality of design. Less time. No geographic limitations.


When It Makes Sense to Spend More

That said, there are situations where investing more in the project makes sense.

Very complex renovations. If you're merging two apartments, relocating many services, working on load-bearing structures — the technical complexity requires more design work and more technical drawings. The cost increases justifiably.

High-value properties with special materials. If the project involves rare marbles, bespoke design furniture, finishes requiring specialist craftspeople — the professional needs specific relationships and expertise in that segment. The higher cost is justified.

Those who want weekly physical site supervision. Going on site, checking the execution, resolving problems in real time. It's a specific service that online packages don't include — and one that has a justified cost when genuinely needed.


Site Supervision: A Choice, Not a Limitation

This is the part where I want to be completely transparent, because it's a question we receive often and it deserves an honest answer.

Site supervision is the service through which a professional physically oversees the execution of the building work, verifying that works are carried out according to the agreed project and intervening when something goes wrong.

Restylit does not carry out physical site supervision. Not because we're not capable — but because we've chosen not to, and that choice has a precise logic.

Effective site supervision requires physical presence, local knowledge, direct relationships with local contractors, and the ability to intervene quickly when something goes wrong. A remote professional cannot do these things as effectively as someone who is physically on site.

What we do instead — and what many people underestimate — is deliver to the contractor a project so detailed that it drastically reduces the need for continuous supervision. Photorealistic renderings, executive technical drawings, a shopping list with precise specifications for every material, a cost estimate. A competent contractor who receives this material knows exactly what to do and how to do it. The margin for error drops significantly.

We always recommend entrusting site supervision to someone who does it professionally and is on the ground: the site manager of the contractor itself, a local surveyor or trusted technician. This is the person who knows that specific firm, its workers, its habits. They know how to communicate with them, they know where to step in.

What we offer in addition is an initial brief for the contractor: a document that explains the project, the priorities, the design choices and the materials, so that whoever supervises the work has a clear reference to follow. It doesn't replace site supervision — it supports it.

If you're looking for someone to manage every aspect of the site physically, Restylit is not the answer for that part — and we tell you so clearly. But if you're looking for a serious, complete and well-documented interior design project that puts that person in the best possible position to do their job well, that's where we come in.


How to Evaluate a Quote Before Accepting It

Three questions to always ask before signing.

1. What does it include exactly? 3D renderings yes or no? Technical drawings for the contractor yes or no? How many revisions? How many video calls? Purchasing support? The difference between a €1,500 project without renderings and a complete €4,000 one isn't just price — it's service.

2. Who actually works on my project? In a large studio the client pays for the principal's name but the project is done by a junior. At Restylit every project goes through the internal team coordinated by Mattea. Always ask who signs off and who does the work.

3. Can I see the result before the works start? The photorealistic 3D rendering is the answer. If the service doesn't include renderings — or only includes generic conceptual sketches — you're buying advice, not vision. The difference is enormous when it comes to making purchases.

FAQ

How much does an interior designer cost for a 100sqm apartment? With a traditional physical studio: between €5,000 and €15,000 for the project alone, depending on city and complexity. With Restylit Essential: €3,300. With Restylit Advanced: €5,500. In both cases the project includes 3D renderings, executive technical drawings and a shopping list.

Is the interior designer included in the renovation cost? No, almost never. The cost of the interior design project is separate from the building work. It needs to be planned as a standalone line item in the budget — and done before the works, not during or after.

Can I deduct the cost of an interior designer? The interior designer's fee is not directly deductible as a professional expense. However, if the professional is registered with the architects' board and signs the planning applications, their fee may fall within the 50% Renovation Bonus expenses. Always check with your accountant.

How long does it take to have the project ready? With Restylit Essential and Advanced: approximately 60 days from when materials are received. With a traditional physical studio: 2-6 months. The difference depends mainly on the timelines for site visits, revisions and coordination, which in the online model are much more streamlined.

Is it worth paying more for a studio with a famous name? Depends on what you're looking for. A famous name brings a precise aesthetic positioning and a network of relationships in the luxury furniture world. If you're looking for a project that reflects that positioning and you have the budget, yes. If you're looking for a quality project that works for your daily life in your specific apartment, a famous name doesn't necessarily add value compared to a competent and methodical team.

What's the difference between an interior designer and an architect for a renovation? A registered architect can sign planning applications, carry out structural calculations and take on the technical and legal responsibility of the project. An interior designer handles the interior design: layout, materials, furniture, lighting, the aesthetic of the spaces. For a renovation involving structural modifications or planning applications you need an architect or engineer. For the interior design project that defines how the space will be lived in, you need an interior designer. The two figures often collaborate: the architect manages the technical and regulatory side, the interior designer the design and furnishing side.

What is an interior design executive project and what does it include? An interior design executive project is the complete document that translates the design vision into concrete instructions for the contractor. It includes: furnished floor plans with precise measurements, photorealistic 3D renderings of every space, executive technical drawings (lighting layout, services layout, construction details), a shopping list with exact specifications for all chosen materials and products, and a cost estimate. It's the document a competent contractor can pick up and follow without ambiguity. Without an executive project, every choice is made on site — often badly and in a hurry.


Restylit is an Italian interior design company, entirely online. We design residential spaces with photorealistic 3D renderings, shoppable lists and technical drawings for the contractor — across Italy and Europe.
