Usually what we need in a house is a floor, walls, ceiling, a roof and trusses to hold it up and then separating walls. These are dependent on what you intend to use the house for; whether a shed, whether a store for your gunias of maize and beans or whether a house for family accommodation or to let.
The Family House – kitchen, sitting area, utility room, master bedroom, normal bedrooms (whatever number needed) and a bathroom or two
Common living areas (this is the sitting room) even those small ones in shagz should accommodate say, two sets of sofa(Assuming each set has a ‘master’ sofa of a typical size of 2.4×0.9m and two secondary sofas measuring approximately 2×0.9m), a dining table, a cabinet (the kabati holding mum’s plates and dishes for the visitors) and of course room for movement. This should all fit in in an area of approximately 6 by 6 m.
This varies depending on needs of an individual and is usually the biggest room in the house.
Living area with sitting area, dining area and room for movementThe kitchen should allow triangular movement all around to prevent bumping and to allow for more than one individual at once.
The kitchen should fit a few cabinets, a cooker, a fridge, a cooking table and leave some area for movement. The size of a normal comfortable kitchen where mama can cook and mzee can still get his beer and nyama for barbeque from the fridge should be about a room measuring about 3.2 m by 4m. If a breakfast area is necessary, it should occupy an area of about 3m by 3m; the kitchen would then be about a size of 4.6m by 4.2m.
A store for mum’s cereals and other stuff) should measure about 1.8 m by 2.4 m at a minimum. This also serves as the utility room. Larger sizes are possible.
The bedrooms will differ in sizes depending on whether en-suite (has a bathroom with a shower and a toilet in it) or normal. A master bedroom is usually bigger and should allow space for a bed (say 6 by 6 which should be around 1.83m by 2m), a cabinet/wardrobe, space around the bed for moving around and some space to act as a dressing area. The total area should be about 4m by 4m. Extra space for the bathroom should be added.
In the other bedrooms (usually for the totos and wageni), plan for a normal sized bed of about 1.35m by 1.9m. If necessary a 1.83m by 2m sized bed may be planned for. A space of about 3.4m by 3m should be enough for this bedroom.
The size of a bathroom is dependent on whether it is a toilet only or toilet and shower are combined
Therefore, the total space you need for a two-bed roomed house should be about; kitchen (3.2 by 4m = 12.8 square meters), store(1.8 by 2.4m = 4.32 square meters), master bedroom (4 by 4m = 16 square meters), one normal sized bedroom (3.4 by 3 m = 10.2 square meters), sitting area (6 by 6m = 12.8 square meters) and two bathrooms (each 1.83 by 1.83m = 3.34 square meters). A total area of 62.8 square meters should be enough for a comfortable two bed-roomed house.
Other areas that you could include are a garage (for the car and also for storage) that should measure around 2.4m by 4.9m = 11.76 square meters) and a study (around 2.8m by 2.4m = 6.72 square meters) both usually for the mzee.
With this added space total area will be about 81.28 square meters
A normal sized plot (usually one eighth of an acre) in Kenya measures about 500 square meters. This land is enough to build a house, a pool and even farm!
