The family, which is among Kenya’s biggest landowners, wants to build the mixed-use development on an 11,000-acre farm that is currently occupied by its giant dairy processor Brookside.

The Kenyatta family has taken a key step to realising its long-held ambition of building a city on its vast land holdings outside Nairobi, with a formal application to authorities for an environmental audit of the project.

Northlands, as the planned city is known, is expected to dwarf similar projects such as Tatu City, and incorporates low-to-high income residential areas, commercial space, a central business district, schools, an industrial area and an agricultural zone.

Its strategic location near central Nairobi and the Jomo Kenyatta International Airport (JKIA) is highlighted in the report as major advantages for those seeking to live or conduct business there.

A total of 3,570 acres have been set aside for residential housing—including low density residential (3,134 acres), high density residential (306 acres) and medium density residential (130 acres).

The medium residential area will have 670 town houses and 368 housing units in flats while the low density area is reserved for 601 villas and 1,320 townhouses.

Northlands will also have a high-density residential area on which blocks of flats having 6,980 housing units and 3,100 townhouses will be built while 390 acres have been set aside for a business district, including 33 acres for a mall/hotel and two acres for a clubhouse.

The SEA report says that the master plan will be implemented in four phases over a period of 50 years.

The report indicates that the quarter-a-million residents will put intense pressure on the Eastern bypass and Thika superhighway, highlighting concern over the project’s possible impact on human and vehicular movement in the area.
