The process often starts with a planning stage in which plans are prepared by an architect and approved by the client and any regulatory authority. foundations are laid and trenches for connection to services such as sewerage, water, and electricity are established. If the house is of brick construction, then courses of bricks are laid to construct the walls. Floors, beams and internal walls are constructed as the building develops, xwith plumbing and wiring for water and electricity being installed as appropriate. Once the main structure is complete, internal fitting with lights and other fitments is done, and the house may be decorated and furnished with furniture, cupboards, carpets, curtains and other fittings.
