Project Description

Nestled in the pine dunes overlooking Lake Jugla, the Twin House is designed to merge harmoniously with its natural surroundings. The main living volume rises above ground level, framing the landscape through wide glazed openings and transforming nature into the focal point of the interior. The atmosphere is defined by serenity and a sense of retreat — a deliberate contrast to the pace of urban life nearby.

The site posed a unique challenge: a five-meter difference in elevation between its highest and lowest points. The solution was to anchor the ground floor in reinforced concrete, housing workspaces and technical rooms with direct views of the forest, while elevating the main living spaces to the higher level. Constructed in timber with ecological finishes — including wood-fiber insulation and lime plaster — the upper floor contains bedrooms, a spacious open-plan living and dining area, and a terrace. A dramatic cantilever with a 3 × 6 m panoramic window frames uninterrupted views of the lake.

The twin house typology was introduced as a rational response to the land plot, accommodating two families while ensuring privacy. From above, the buildings form the shape of an "H", with terraces positioned between the volumes. Careful orientation and blind facades mean that the residents are never disturbed by one another, even when living side by side.

The interior, designed by Ieva Leja continues the dialogue with nature: calm, Scandinavian tones, oak flooring, and expansive glazing create a sense of openness and continuity with the outdoors. Custom concrete and timber details, crafted staircases with glass balustrades, and bespoke full-height doors emphasize spatial clarity and light. Subtle material contrasts — raw concrete balanced by natural wood and soft textiles — ensure both longevity and warmth.

Performance & ROI Highlights

  • Energy Efficiency: The house integrates modern technologies such as a ventilation system with heat recovery, remote-controlled heating, and irrigation systems. High-performance glazing and natural insulation materials contribute to year-round energy efficiency and comfort.

  • Material Reuse: Concrete from the original structures was demolished and replaced with a new system, while timber and ecological materials were chosen for their sustainability and resilience. Built-in storage solutions and multifunctional furniture ensure long-term adaptability and efficient use of space.
