Selling a plot to a builder: the information pack that helps assess your land

1. Start with your goal as the owner

Clarify whether you want to sell the land or find a company to build on it. These are different conversations: one assesses a possible purchase, the other a construction project. Note the municipality, location, area recorded in your documents, access and current situation. State whether buildings already exist or issues remain unresolved. The first information pack does not need to promise a spectacular development: it needs to help identify what information is missing for an assessment.

2. Separate cadastral, land registry and planning information

Spain’s Cadastral Electronic Office provides cadastral information and mapping. The Land Registry provides information about registered rights; a nota simple is an informational extract. The feasibility of a specific building must also be checked against planning rules and with the competent local authority. Do not present a cadastral reference as sufficient proof of building potential. If two documents show different areas, flag the discrepancy and request professional review before treating a figure as definitive.

3. Prepare a short summary and an organised appendix

On the first page summarise the location, objective, documented area, known situation and owner’s contact details. In the appendix collect the available documents with their dates and origins, without inventing missing ones. Add current photographs from access points and visible boundaries, plus a location plan. Distinguish verified information from outstanding checks: a possible utility connection, apparent access or estimated number of homes needs verification before becoming a sales claim.

4. Explain possibilities without presenting them as certainties

If you have planning information, identify who issued it and its date. If you do not, say so and propose checking it. Avoid statements such as “eight homes can be built here” without technical and planning evidence for that plot. A builder or developer will need to study all the conditions and costs. An attractive photograph cannot establish the number of interested parties, and an initial conversation is not an offer to buy.

5. Compare complete proposals, not just figures

When there is interest, review what documentation is requested, which checks remain outstanding and what conditions accompany the proposal. Before accepting exclusivity, reservations, deadlines or obligations, obtain professional advice appropriate to your transaction. A difference between two amounts may reflect different conditions. This guide organises the initial presentation; it does not value the land or replace a legal, planning or technical review of the case.

6. Present the plot confidentially

Constructores.com works directly with owners and does not accept intermediary proposals for this service. You can submit your plot to explore contacts with builders and developers, or explain that you are looking for someone to build on it. The initial submission is stored in a private inbox; you are consulted before information identifying the land is shared. An enquiry does not guarantee a buyer, offer, availability or sale timescale. A clear information pack helps start the conversation with useful information.
