Building in Kirinyaga: climate, ground and materials

General guidance, not an assessment of your site. What follows describes conditions typical of Kirinyaga or of a named part of it. It does not hold everywhere in the county, and ground, drainage, access and materials can change from one plot to the next. Before you design, budget or build, have the actual site examined by a qualified professional — a registered engineer, with a soil investigation where the ground is in any doubt. Do not base foundations or a budget on this page alone.

County headquarters Kerugoya; other main towns Kutus, Kagio, Wang'uru, Sagana.

The north of the county rises towards Mount Kenya on red volcanic soils; the Mwea rice plains in the south are black cotton.

Cool highland climate

Much of Kirinyaga is temperate by day and cold at night, with reliable rainfall and, at altitude, frost on clear nights. Where that holds, it asks this of a house:

  • A ceiling and some roof insulation make the biggest difference to comfort on cold nights.
  • Face the living rooms to the morning sun and keep the windows on the cold side modest.
  • Pitched roofs with properly sized gutters handle the rain; plan the site drainage before the foundations go in.

Black cotton soil on the Mwea plains around Wang'uru

Black cotton soil is an expansive clay: it swells when wet and shrinks and cracks when dry, and ordinary strip footings on it crack the walls above. Foundations are taken down to firm ground or the clay is replaced with compacted murram, and ground beams or a raft are common. Budget noticeably more for the substructure than the figures above assume, and get a soil test first.
