The builder you choose will shape your house more than any material. Here is how to find, compare and work with a contractor in Croatia, especially if you live abroad.
Most people who build or renovate in Istria do it once. The builder does it every year. That imbalance is the root of most problems, and the way to correct it is preparation: a clear brief, a good architect, a fair contract and someone on site who looks after your interests. None of this requires distrust. Good contractors prefer clients who know what they want.
This guide is general. Contract law, licensing and liability rules in Croatia are specific and change over time, so treat what follows as a framework and take legal and professional advice for your own project.
Start with the architect, not the builder
It is tempting to call a builder first and ask for a price. Resist it. Without drawings and a written description of the work, every builder will quote something different, and you will have no way of comparing them. A local architect prepares the design and the documents needed for any permit, and can describe the work precisely enough for builders to price the same thing. Many architects also know which contractors do good work on the kind of house you have. Our article on the architect and atelier working together explains how the roles fit.
Where to find good contractors
- Recommendations from your architect or engineer. They see contractors at work and know who finishes on time.
- Neighbours and owners of recent projects. Ask who built the house you admire, and whether they would hire them again.
- Local trades for specialist work. Stonemasons, roofers and joiners who know traditional techniques are often small firms booked well ahead.
- Your own visits. Go and see completed work, and if possible a site in progress. A tidy site says a lot.
What to check before you shortlist
Ask whether the company is properly registered to carry out the work in question and what insurance it holds. Ask for references from clients whose projects are similar in size and type to yours, and actually call them. Find out who will run your site day to day and whether the main trades are employed directly or subcontracted. For a stone house, ask specifically about experience with lime mortars, repointing and timber roofs; a firm that mostly builds new concrete villas may not be the right one for a restoration.
How to compare quotes
Send the same written description and drawings to at least three contractors and ask them to price it item by item rather than as a single total. When the quotes come back, look first at what is excluded: scaffolding, waste removal, temporary power and water, site protection, cleaning. A low quote that leaves these out is not a low quote. Then look at the materials specified. If one builder has priced cement where the brief asks for lime, or a cheaper window than the one drawn, the numbers are not comparable.

The contract
Always have a written contract, and have it reviewed by a lawyer who works in Croatian construction before you sign. In general terms, a good contract describes the scope of work by reference to the drawings and specification, sets out the price and how it can change, links payments to completed stages rather than to dates, defines the timeline and what happens if it slips, and explains how defects are handled after completion. It should also say how changes you request during the build are agreed and priced, because changes are where budgets usually drift.
If you do not speak Croatian, ask for a translation of the contract or work with a lawyer who can explain each clause. Signing something you have not fully understood is the most common mistake made by owners from abroad.
Supervision when you live abroad
Most owners cannot be on site every week. Someone independent of the builder should be: an architect providing design supervision, a supervising engineer or a project manager you trust. Their job is to check that the work matches the drawings, to approve stage payments and to raise problems early. Agree a rhythm of site visits and photo reports from the start. Regular short updates are better than a long report when something has already gone wrong.
Warning signs
- Pressure to start before drawings or permits are ready. Delays at the start are cheaper than problems later.
- Large payments in advance. Payments should follow completed work.
- No written contract, or a vague one. "We'll sort it out as we go" usually means you will pay for it.
- Reluctance to give references. Good builders are proud of past clients.
- Answers that change. If the scope, price or timeline shifts every time you ask, expect the same on site.
Plan the interior alongside the build
Kitchens, wardrobes and built-in furniture are often left until the walls are finished, and then the sockets, pipes and niches are in the wrong places. Bring the interior into the conversation while the builder is still on site. Lampisa, our partner atelier, works from your moodboard to a 3D render of each room, so the builder can prepare walls, power and plumbing for furniture that has already been agreed. Everything is built in plywood, not particleboard, which matters in a coastal climate. See how it works on the from moodboard to render page, and read what drives the cost of a stone house renovation before you budget.
