Interior Designer vs Architect: Which One for Your Villa, and When?

The architect starts by reading the plot. Zoning status, setback distances, floor heights, the sun's path through the day, the view and the wind all come together in the decision of where and how the building will sit. In villas these decisions directly shape the quality of life: which room you will have breakfast in, whether the pool sits in shade or sun in the afternoon, which door leads out to the terrace — the architect settled all of this while the project was still being drawn.

• Massing and siting — How the building sits on the plot, levels, the balance of view and privacy.
• Structural system — Columns, beams, shear walls; in other words, everything you can never move later.
• Permits and regulations — Zoning, building permit, occupancy certificate; if this paper chain breaks, construction stops.
• Facade and shell — Exterior appearance, roof, insulation, window proportions, the way light enters.
• Core spatial layout — How the rooms relate to each other, the floor plan, circulation.

The interior designer tunes the inside of the shell to your life. Not where the wall ends, but what texture, what color and what light that wall greets you with. From the height of the kitchen counter to the number of sockets, from the depth of the built-in wardrobe to the cable of the bedside lamp. This is where an interior designer's real value shows in a villa; because luxury is felt not in expensive materials, but in every detail being exactly where it belongs.

• Interior layout — Furniture placement, circulation, scale; making the room feel right rather than merely big.
• Materials and texture — Flooring, wall finishes, marble, wood, metal; all of them in conversation with each other.
• Lighting design — Layering ambient, accent and task lighting; this is what makes a villa livable after dark.
• Wet areas and kitchen detail — Bathrooms, kitchens, dressing rooms; spaces that work to the millimetre.
• Built-in furniture and storage — Fixed, made-to-measure solutions produced specifically for the villa.

Because the decisions are intertwined. If the interior designer dreams of a six-meter uninterrupted glass wall and a concealed library in the living room, it is the architect who designed the structure who says whether that is possible. If the architect wants to drop the ground floor by half a level, it is the interior designer who sees how that affects kitchen ergonomics. If these two disciplines do not sit at the same table at the start of the project, you will close the gap between them later — with your money and your time.

The most expensive thing in a villa is not the marble; it is the "I wish this had been done differently" you notice once the structural work is finished.

1. 1I am building a villa from scratch — Start with the architect and bring the interior designer in at the schematic design stage. The interior designer must be at the table before the plumbing and electrical drawings are made; otherwise sockets, lighting circuits and shafts end up in the wrong places.
2. 2I bought a villa with the shell complete and the interior empty — Now the interior designer takes the lead. The architect steps in only where the structure is touched: removing walls, altering the facade or intervening in the roof.
3. 3I am renovating my old villa — Start with the interior designer; but the moment you want to remove a wall, ask an architect or a structural engineer. The question "is this wall load-bearing?" can turn into tragedy when walls come down before it is answered.
4. 4I only want decoration — What you need is an interior designer or an interior design team; no architect required. Just note that in a villa, "only decoration" usually ends up touching the lighting and the services too; factor that in from the start.

A clear warning: the "per square meter" tables you find online are misleading for villas. Picture two two-story villas of the same size; one has a pool, a smart home system and a natural stone facade, the other standard render and ceramic tiles. Their costs can easily diverge by a factor of two. That is why a serious team will draw up a room-by-room finishes schedule for you before quoting any headline figure.

A finishes schedule is the document that records, line by line, which material, which brand and which workmanship every room of the villa will be built with. The price is generated from that list: item by item, transparent, comparable. Stay away from offers that say "turnkey for this much" without stating what they cover; the most common disputes in villa projects arise from items that were never written into the contract.

When you hire the architect from one place, the interior designer from another and the contractor from somewhere else entirely, you also take on an invisible job: coordination. When something goes wrong, the architect points to the contractor, the contractor to the interior designer, the interior designer back to the architect — and you are the one left in the middle. Vesya's approach of running everything under one roof, from design through implementation to construction, exists precisely to close this gap. When the same team holds the villa's shell, its interior and the work on site, the architect's and the interior designer's decisions align from the very first drawing; nobody can say "that wasn't my job".

This does not mean you must work with a single firm. Two separate offices can produce a superb villa too — as long as you can keep them at the same table, on the same schedule and under a single chain of responsibility. When making your decision, ask one question: who owns this project end to end?

• References — Has this team worked at villa scale before, or does its experience stop at apartments?
• Scope — Will the interior designer and the architect work on the same schedule, or does one start only when the other finishes?
• Documentation — Will I get a finishes schedule and an itemised quote, or just a lump-sum figure?
• Implementation — Will the team that designs also follow the site, or withdraw once the drawings are delivered?
• Changes — If I change my mind during construction, how are the cost and the process managed?

The right setup is actually simple: the architect resolves the villa's skeleton and its permits, the interior designer makes the inside livable, and the two sit at the same table from day one of the project. The day you get that trio in place, the question "which one should I hire" answers itself.
