You can calculate about 18,000 to 20,000 pesos per square meter of construction of a one floor house. This is a concrete block house with a concrete roof. Basic construction, what is called first class. You can go lower, with tin sheet roof, thinner walls, plywood doors, pine frames, cheap sanitary installations and so forth. A lot depends on the design of the house and who builds it, and who supervises the construction.
