An existing building of communal gardens becomes a neighbourhood house. Rather than erasing, the project works with what remains: concrete walls and slabs are retained as the structural spine, while dismantled timber from the existing roof is reused as a bicycle shelter at the entrance.

A single sloping roof unifies the whole, assertive, immediately legible, scaling the building against the forest edge to the west and the school complex to the east. Beneath it, the eastern half opens generously onto the park through full-height glazing, flooding the multipurpose halls with light and landscape. The western half, more compact, anchors the programme in the existing masonry band.

The project is less an addition than a transformation: inherited material given new purpose, existing volumes brought into the light.
