Underground museum approached by a treetop walkway
Stonewood Design with Mark Thomas Architects plus Henry Fagan Engineering (Treetop Walk Way) for Emily Estate UK
Contract value: undisclosed
This underground museum has a long glazed elevation opening onto woodland and its grassed roof is inhabited by the estate’s deer herd. Approached via a tree-top walkway over a wooded dell, the building is glimpsed at canopy level before the bridge splays out into a terrace. Its glazed facade has 5m high sliding doors while the interior is simple insitu concrete, lessening the cooling and heating load. The concrete southern wall of the museum uses local Hadspen stone aggregate, grounding it in its place. The underfloor heating is fed primarily by a ground source heat pump and a MVHR system minimises the energy required for air heating and cooling.
