In terms of the cost of restoring a farmhouse in Le Marche, it is not possible to give precise figures because much depends on two important factors. Firstly, the amount of work that has to done and secondly the quality of the materials that are used. A good start is the “Prezziario Regionale” or Regional price list, which gives current cost of all materials and work.
Using this price list, your architect should be able to write a full specification with relevant costs. Then, normally, building companies quote a discount of between 3-10% composed with the official Regional price.
All things considered, one should calculate € 1300 per sqm for a complete restoration to a good standard. This figure would include the cost of the architect and tax.
