Where Timeless Design Meets Energy Efficiency in Residential Construction

Hochheim, a charming wine town, offers the best of both worlds: proximity to the Taunus region, scenic vineyards, and easy access to major cities like Frankfurt, Wiesbaden, and Mainz. With housing in short supply, the Mainz-based firm mz³ architekten ingenieure designed a striking residential building for a regional developer—one that combines solid monolithic construction with refined, distinctly modern lines. The result is more than aesthetically impressive; it delivers on the client's vision of sophisticated, universally appealing architecture while achieving rigorous energy standards (KfW Efficiency House 55) and accommodating a diverse mix of living spaces—from individual units to shared community living.

The six-unit residence features a distinctive brushstroke plaster finish that creates an exclusive façade with striking textural depth. The architects employed a sophisticated house-within-a-house concept, offering four maisonettes with roof terraces or gardens (up to 140 m²) and two compact two-bedroom apartments (around 60 m²) on the first floor. The development plan's emphasis on single-family and semi-detached homes presented a creative challenge, requiring the architects to maximize the site while respecting neighborhood context. Their solution: positioning the building across two separate plots with two independent stairwells serving three units each. Rather than compromise with a recessed top floor, they crafted something bolder—a two-sided setback with a cantilevered terrace structure that seems to float above, actually reinforcing the building's clean geometric language.

The architects prioritized efficient floor plans that offer flexibility and treat corridors as additional living space. Room placement follows solar orientation: bathrooms face east, living areas southwest. Large south- and west-facing windows paired with smaller northern openings flood the interiors with light. Energy performance comes from multiple systems: a geothermal heat pump, photovoltaic panels, selective bus control systems, and decentralized ventilation—delivering the necessary environmental credentials without sacrificing comfort.
