CONTEXT Surrounding the building of a maximum "use" of existing laws and zoning requirements on the principle that more squares meters for the least investment. The plot is surrounded on three sides cy the road, and on the fourth by semi-detached house. Zoning requirements demanded hip roof with round tiles.
