The two mixed-use buildings stand as gateways to a new residential district conceived under a Lausanne city masterplan. The Fiches-Nord neighbourhood forms part of a policy to create housing along public-transport corridors. Acting as a hinge between an existing cluster of office blocks and the new dwellings, the pair combines both functions—tertiary and residential. This programmatic blend, which exploits the site’s differing orientations, becomes the project’s guiding morphological and typological theme.
Identical in layout, the buildings take the shape of irregular hexagons, lending each a distinctive presence. The line that splits office space from housing runs along the plan’s median axis: workspaces face north-west towards the business quarter, whereas the flats enjoy south-eastern sun and panoramic views of Lake Geneva and the Alps. This geometry achieves high density while preventing close face-to-face overlooking. Separate identities are reinforced by entrances on opposite sides, feeding two back-to-back stair cores divided by a coloured-glass wall that theatrically underscores the boundary between public and private circulation.
Apartment plans capitalise on the hexagon: living areas occupy the plan’s outward flares, while bedrooms revert to orthogonal layouts. Responding to the dual programme, the façades merge the openness of an office curtain wall with a continuous glass guardrail whose graduated screen-printed motif wraps the volume. Clear glazing is paired with lightly turquoise-tinted panes set in bronze metalwork, giving the ensemble a strong identity that captures and reflects both city and landscape.
