During the time of expansion after World War I, the Canes constructed an additional building from a disassembled army hut that was bought for 25 pounds and sent up from Nairobi on the train. Standing directly in front of the present dining room, this building served first as a tea room and later as a church when the Baptists purchased the property. During Brackenhurst’s era as a hotel under the Canes, two additions were added to the building, the first serving as a bar and the second as a billiards and grill room.

After 1964, the year that the Baptists purchased the property, these rooms were converted to a conference room and tea room. When these rooms were beyond repair, the original hut and second addition were removed in 2004, endowing the main building with a beautiful view. The third addition remains as a quaintly attractive tea room.

In 1927, the spacious dining room was built on the patterns of an old English tithe barn for which Mr. A.B. McDonnell, a nearby neighbour and talented architect, drew the plans. In the dust of a downtown Nairobi street, Mrs. Cane traced the design on some roof beams. An Indian artist and craftsman faithfully copied the drawings while hand carving the beams, later sending them by wagon to Brackenhurst. Oral history has it that the building plan was drawn in feet but built in yards.

Just as the walls of the dining room were completed and part of the beams put in place, the Limuru area experienced a severe earthquake, but not a single splinter fell from the partially constructed building.
