Section A, looking east. The roof falls from 7.2 m at the living end to 5.6 m over the bedrooms.

Larch House sits at the top of a sloping plot on the edge of Wivenhoe, with the lane to the north and the Colne estuary opening out below the garden to the south. The plan is simple: a twelve-metre timber frame, one room deep at the living end, with every principal room facing the water. The living room is double height under the high end of the mono-pitch roof; a gallery library runs above the kitchen and looks back into it.

The house was built by the current owners over fourteen months and completed in May 2019. It is sold with the full set of Marta Ilves Architects' drawings, the structural calculations, the air-test certificate and the ten-year structural warranty, which has four years to run.

05 · Location

Wivenhoe: a quay, a university, a railway station, and an estuary that empties twice a day.

The house is on Anglesea Lane at the eastern edge of the town, where the last houses give way to the marsh footpath. It is a quiet, unmade lane with six other houses; the estuary path runs along the bottom of the garden to the quay in one direction and to the Alresford creek in the other.

Wivenhoe has two pubs on the water, a bookshop, a good baker, a primary school rated outstanding and the University of Essex campus on foot. Colchester, with its market and the mainline, is fourteen minutes by train.
