How much does an architecture project cost? How the fee is calculated

"How much does an architecture project cost?" is usually the first question from anyone planning to build. The correct answer isn't a figure — it's a structure: the fee depends on what you're designing, how complex it is, and which phases you include. Below we explain clearly how an architecture fee is worked out in Romania, what drives the price, which costs are not part of it, and how to request a quote you can compare properly.

How the fee is calculated: three models

In practice, an architecture studio may propose the fee in one of three ways:

• A percentage of the investment value. The fee is a percentage of the estimated construction cost. The larger and more complex the project, the larger the basis of calculation. This is the classic model, also used in international practice, because it ties the design effort to the real scale of the work.
• An amount per built square meter. The fee is expressed as a value per square meter of gross floor area. It's easy to understand and compare for homes, but read it carefully: what matters enormously is which phases that price includes.
• A fixed (lump-sum) fee. A set amount, agreed at the start for a well-defined scope. It works for clear projects with a stable brief, and less well where requirements change along the way.

Whatever the model, a serious fee is set only after the architect understands the brief, the site and the budget — not "off the top of the head" over the phone. A number given without that information is a guess, not a quote.

What drives the price

Two houses of the same area can carry different fees. The main factors are:

• floor area — the gross built area, in square meters;
• typology and complexity — a simple single-family home is very different from a building with a special structure, large spans or mixed uses;
• the phases included — from concept through to execution details and site supervision (see below);
• the disciplines coordinated — structure, building services (electrical, plumbing, heating), and related designs that must be aligned;
• the site — slope, shape, geotechnics and access can complicate the solution;
• urban planning — if the project first requires a PUZ or PUD, an extra stage of documentation and approval appears;
• the level of customization and number of revisions — how much the solution is refined together with the client.

The phases of a project — and why what you include matters

A fee only makes sense in relation to what the architect delivers. A project usually goes through several phases:

• concept / preliminary design — the basic solution, massing and spatial organization;
• DTAC — the technical documentation for the building permit (what is filed with the city hall);
• PTh — the technical project, on which construction is based;
• DDE — the execution details;
• site supervision — the architect's presence during construction.

The same building can be "designed" only up to the permit, or taken all the way to execution details and site work — and the price difference is natural, because it's a difference in effort and responsibility. When comparing offers, always check how far each one goes.

What is not included in the architecture fee

A common source of confusion: the design fee doesn't cover everything you pay to reach the permit. Separate from it, in general, are:

• the approval and permit fees charged by the city hall and the issuing bodies;
• the project verification by a certified verifier, required by law;
• the topographic survey and the geotechnical study, needed for design and approval;
• any expert reports, studies or urban-planning documentation (for example a PUZ), when required by the urban certificate.

A fair studio tells you from the start which costs are inside the fee and which come separately, so there are no surprises along the way.

How you pay: by phase, not all at once

Normally payment is staged across the project's phases: an advance at the start (concept), then installments as each stage is delivered — DTAC, PTh, and so on. The advantage is twofold: you spread the financial effort and you pay as you receive concrete results, phase by phase.

"Cheapest" is rarely the cheapest

A low fee often hides an incomplete or poorly coordinated project — and the cost comes back later, amplified: rejections and corrections at approval, changes during construction, services that don't match the structure, finishes and solutions chosen in a rush. A project thought through in time is almost always cheaper in the end than one that was cheap at the start. The architecture fee is a small percentage of the total investment, but it directly influences the rest of the costs.

How to ask for a quote you can compare

To get comparable offers, prepare a few things before asking for a price:

• the site — the urban certificate or, at least, the zone's regulations (POT, CUT, height regime);
• the brief — what you want to build, for whom, with which functions;
• an indicative investment budget and the area you want;
• the timeframe in which you want to move forward.

Then ask each studio to state clearly how far the offer goes, which disciplines it includes and how many revisions are covered. That's the only way to compare like with like, rather than a cheap concept against a complete project.

At Beletage

We always start with an initial conversation: we understand the site, the brief and the budget, then we give you a clear, phased offer for your project. If you'd like a low-commitment first step, we also have consulting packages that clarify from the outset what you can build and at what cost. Have a plot or an idea? Let's talk — we'll tell you straight what to expect.
