OAD restores Soviet military bunkers as a seaside home in Latvia
SAR is a seaside residential project designed by Open Architecture Design (OAD) on the Saraiki coastline in Latvia. The house is built on the remains of Soviet-era military bunkers originally constructed to protect the fragile Baltic coastal dune habitats. The project adapts these existing structures into a residential complex composed of a main house and two guest houses for a multi-generational family.
The site contained four abandoned bunkers partially covered by vegetation. Rather than removing them, the design incorporates these foundations into the new residential program. The intervention reuses the structures as the base for the main dwelling and two smaller guest houses, establishing a relationship between the existing military infrastructure and the new domestic environment.
The main residence is defined by a large dual-sloped roof that follows local architectural regulations while introducing a contemporary material expression. Fiber cement panels clad the roof surface, referencing the material language associated with Soviet-era construction. To support the roof above a glass facade, OAD developed a custom metal frame that functions both as a structural solution and as a visible architectural element. The main living spaces are located on the second floor, while the entrance is positioned beneath the elevated volume. The house spans two bunker foundations, effectively bridging between them. This configuration increases the interior floor area while limiting direct impact on the surrounding landscape.

SAR residence reinterprets the form of the original bunkers
The two guest houses draw directly from the form of the original bunkers. Their low volumes are covered with grass roofs, allowing them to merge visually with the coastal terrain while extending habitat conditions for local fauna. The contrast between the elevated main house and the grounded guest structures defines the spatial organization of the site. One element appears suspended above the landscape, while the others remain embedded within it.
Inside the main house, the interior design by studio Open Architecture Design – OAD emphasizes restrained material choices and simple detailing. Wooden finishes, exposed concrete floors, and tactile surfaces define the interior environment. The layout responds to natural daylight conditions. The main living area is oriented to receive morning light, while the master bedroom includes openings directed toward sunset views over the Baltic Sea. A continuous glass facade strengthens the visual connection between interior spaces and the surrounding coastal landscape.
Through the reuse of existing bunker foundations and the careful placement of new structures, SAR project explores how domestic architecture can be integrated within a historically layered coastal environment while limiting its physical footprint on the site.
