Extending Heritage Community library with Reclaimed Timber Pavilion

Lea Bridge Library Pavilion, designed by Studio Weave , is a 250 m² single-storey extension to a Grade-II listed Edwardian library in east London, accommodating a flexible café and community facility that reconnects the existing building with adjacent gardens. The structural strategy employs a mass timber post-and-beam system of tapered laminated veneer lumber (LVL) beams supporting an extensive glazed elevation overlooking Friendship Gardens, anchored laterally against an existing garden wall to minimise intervention and maximise site connectivity. A red precast concrete colonnade echoes the material tone of the heritage building while concealing drainage that feeds tree root systems below, addressing sensitive arboricultural constraints. The internal space is defined by reclaimed timber linings and bespoke furniture crafted from trees felled around London, reinforcing a material logic of reuse to reduce upfront carbon, while the plan’s deliberate ‘pinch’ and curved glass element accommodate existing mature trees. Passive environmental strategies include natural cross-ventilation and MVHR support, positioned ceilings to protect exposed aggregate floors from solar gain, and careful daylighting. The project balances structural efficiency, adaptive community use and material sustainability within a heritage context.
