The Roost

House Extension | Rothiemay

Dress for the Weather, with 55N Architecture, were commissioned to design an extension to an existing dwelling in Rothiemay in the north of Scotland by the home owners and Bat Conservation Trust. The loft space of the existing property is home to around 2000 pippistrelle bats. The brief was to provide extra living accommodation on the ground and first floors with a unique bat roost constructed in the new attic space.

Through research and detailing there is provision for bat access and nesting as well as addressing the relationship between the two sets of inhabitants. The profile of the timber cladding allows small spaces for bats to access their new roost space at eaves level, once inside a lattice is created to allow individual roosting spots, a high level external door allows access to occasionally clean out the roost without directly connecting with the human living accommodation. The steeply chamfered reveals are designed to prevent an occurring problem of younger bats landing on standard window cills and entering bedrooms on warmer summer nights when the windows are open.
