The True Cost of a Turnkey Renovation: Where Every Euro Goes

'Turnkey' should mean no surprises. Here's what that structure actually protects you from — and why the cheapest quote is so often the most expensive project.

What turnkey means

One point of contact, one accountability

A renovation splinters the moment responsibility does. The designer blames the builder, the builder blames the supplier, and the client stands in the middle holding a budget that keeps growing. Turnkey exists to end that.

One interlocutor. Deadlines written into the contract. From the first sketch to the day you get the keys, every trade on site answers to the same studio. The price of that is not a premium — it's the removal of the hidden costs that live in the gaps between companies.

The workshop

Why owning the joinery changes the maths

Where a turnkey euro goes

Installations (hidden, structural, essential)~30%
Labour & single-point coordination~28%
Finishes & materials~22%
In-house bespoke joinery~14%
Design & contingency reserve~6%

The joinery line is where an in-house workshop compresses both cost and time versus a subcontracted model.

RITUAL runs its own carpentry workshop, led by our own team. That isn't a boast — it's a line on your budget that behaves differently. Bespoke kitchens and furniture are made in a fraction of the usual time, without the mark-up of an outside supplier and without the delays that outside suppliers cause.

When the people designing the kitchen and the people building the kitchen work in the same house, the drawing and the object stop disagreeing. That is where money quietly leaks on ordinary projects.

The false economy

Why the cheapest quote costs the most

The most expensive renovation is the one you have to pay for twice.

A quote that undercuts everyone else is not a gift. It is usually a number missing its second half — the extras, the 'that wasn't included,' the mid-project renegotiation once the walls are open and you have nowhere else to go.

A serious quote is built from a serious project. It looks higher on day one and finishes lower, because it already contains the things the cheap quote will 'discover' later.

The reserve

Budgeting for the building's secrets

Open a wall in an old Barcelona building and it will surprise you — tired wiring, a pipe that should have been replaced two decades ago, a beam nobody drew. A mature budget carries a contingency for exactly this, so a surprise stays a footnote instead of becoming a crisis.

That reserve isn't padding. It's the difference between a studio that planned for reality and one that hoped for the best with your money.
