Tell us what stage your project is at
You can request house construction, home, kitchen or bathroom renovation, owners' association work or commercial premises renovation. The municipality and a description of the scope are essential to guide the request.
If you know the floor area, dates or budget, you can add them. For a house, state whether you have a plot and architectural project. For a renovation, describe the property's condition and what you want to change.
We review the request before assigning it
Our team reviews the information and may contact you if clarification is needed. The request is assigned to a maximum of three companies according to coverage, specialism and availability.
We operate throughout Spain. You can request construction and renovation quotes in any province. Availability is confirmed for the specific municipality and work. We do not promise a fixed number of quotes or the same timeframe for every project.
Compare proposals and hire directly
Companies may contact you to assess the work and prepare a proposal, subject to their availability. You decide whom to hire.
The building contract and payments are agreed directly with the chosen company. Constructores.com facilitates contact and does not replace the building company or the project's technical professionals.
A free service for you
Requesting quotes and using the AI designer are free for the customer.
You do not need to create an account. When you submit your request, we forward it to up to three construction companies so they can contact you, depending on coverage, specialism and availability. See the privacy policy for how your data is processed.
