Data, sources and review

A construction budget needs plot details, a project and measurements. Planning status, studies, permits, VAT and acquisition costs are reviewed separately.

The calculation does not automatically include property or land purchase, acquisition taxes, permits, professional fees, furniture, utility connections or contingencies: assess these for the actual project.

For a proposal we need the location, available plans or measurements, photographs, project goals and decisions made so far. We can arrange a visit and detailed estimate.

Residential starting levels were supplied by BCN YARD. Visitors provide all other prices.

VAT is not calculated automatically: the rate depends on the transaction and legal conditions. The Spanish Tax Agency describes a general 21% rate for residential renovation or repair and a 10% rate only when the applicable conditions are met.
