Hello Michel

As an architect, our experience tell us that you should expect an average price of around 1000-1500 €/sqm and you should use a building company from outise Algarve.

We just had a small constructing built in July in Lagos (around 200 sqm) and the price we were ask in algarve was 3 times more expensive that using a company from Lisbon.

If you have the architecture project finished, include some companies outise Algarve in the tender process.
