A hide for watching and recording birds at Butlers Farm, a regenerative farm in the Cranborne Chase on the Wiltshire–Dorset border. It sits on the south-eastern edge of Barn Field lake, dug out in 2022, set into the small hill of ground that came out of the lake and facing west over the water. It was designed with the architect Grace Fletcher. It is also a base for visitors: small groups of young people come through the Farming in Protected Landscapes Access for All fund.

The brief was to use as little concrete as possible and to leave the site as it was found. The structure is a set of light, separate parts that can be taken apart again. Small steel tube piles, filled with concrete, go through the made ground to the natural soil, about 3 m down. A light steel frame (S275) sits on the piles and carries the building and a mono-pitch roof canopy that covers the deck. The room itself is an insulated timber box, a C24 stud frame filled with hempcrete, hung within the steel frame. Around the base, gabion walls hold back the hill and protect the timber.

The roof is timber rafters under corrugated metal sheet, and the walls are clad in timber; both will weather in. The structure was designed to Eurocodes 3 and 5, with the external timber treated for service class 3.
