North light over the benches, a blank wall for the timber store. The saw-tooth roof is the cheapest way to get even light across forty metres without a single south-facing window.

Twelve columns, a flat canopy and nothing else. Built in eleven weeks so the birdwatchers kept their season, and detailed so the whole thing can be unbolted and moved.

Four houses under one roof line, each with its own door on the street. The party walls carry the load, so the fronts are free to change without asking the neighbours.

Two wings around an open yard, on the floor of a worked-out quarry. The stone of the retaining wall came out of the same hole a hundred years earlier.

A shed for two boats and a deck to sit on. Larch, untreated, left to go silver at the same rate as the jetty it stands on.
