Johan Sundberg Arkitektur Lifts a Larch-Clad Retreat into the Pines on Sweden's Baltic Coast

A Swedish family living in London wanted a counterpoint to city life: a place where their children could disappear into pine trees, where dinner could stretch into a Baltic sunset, and where architecture would serve as a frame rather than a spectacle. Johan Sundberg Arkitektur answered with a single timber volume threaded through a wooded hillside in Yngsjö, replacing a dilapidated summer cottage that had outlived its usefulness. Completed in 2023, the retreat covers just 1,500 square feet, yet it packs a fully resolved domestic program into what reads from the outside as little more than a confident horizontal line among the verticals of the forest.

What makes the house genuinely interesting is the structural split at its center. The southern half meets the ground; the northern half floats above it on slender pillars, cantilevering the private bedrooms out into the canopy. Between the two halves, a recessed section carves out a sheltered west-facing terrace that captures the evening sun. The move is deceptively simple, but it solves multiple problems at once: it preserves root zones, separates public from private, and gives the building a kinetic quality when approached through the mist-soaked forest.

Arriving Through the Trees

Sundberg refused to clear the site and lay down a formal approach. Instead, you arrive on a stone path that winds between birch and pine, catching the house in glimpses before you see it whole. Morning fog, common along this stretch of coast, turns the Siberian larch cladding into a warm blur against silver bark. The metal stair tucked along the northern facade reinforces the idea that this is a structure inserted among the trees rather than imposed upon them.

Landscape architect Ulrika Sommar Trädgärdsdesign collaborated on the site strategy, which essentially meant leaving the forest intact and planting only where the construction footprint had disturbed the soil. It is a refreshingly restrained decision. No manicured hedge, no gravel courtyard, no deck lights marking a grand entrance. The architecture earns its presence through proportion and material, not by bulldozing context.

The Floating Volume

The northern half of the house lifts off the ground on steel pilotis, a move that keeps the building light on its feet and avoids the heavy foundation work that would have damaged the root systems of surrounding pines. Triple-layered larch panels line the underside, concealing the structure and giving the soffit a finished, deliberate quality rather than the raw plywood look you often find beneath raised buildings.

Vertical pilasters break the larch facade into rhythmic bays, adding depth to what could otherwise read as a flat plane. Double eaves and recessed gutters keep rainwater details invisible. These are quiet details, the kind you absorb rather than notice, and they speak to a designer more interested in discipline than drama. Sundberg has cited the golden era of Scandinavian and early British modernism as a reference, and you can feel it in the proportions: horizontal, precise, warm without sentimentality.

Communal Spaces Open to the Forest

The southern half of the house, where it meets the ground, contains the entrance, kitchen, and a combined living-dining space. Floor-to-ceiling glazing wraps around the communal rooms, dissolving the boundary between interior and garden bed. The slatted larch ceiling runs continuously from inside to outside, pulling the eye through the glass and reinforcing the sense that the house is a permeable screen rather than a sealed box.

Oak floors, oak trimmings, and bespoke oak doors (crafted by Möbelsnickare Kasper Thulin) ground the interior in a warmer, denser grain that contrasts with the lighter larch overhead. Sheer curtains filter the light without blocking the view, a decision that keeps the rooms from feeling like a fishbowl while still honoring the forest setting. The overall palette is two-tone timber, white walls, and daylight. Nothing competes.

The Skylit Corridor

A long corridor connects the communal south to the private north, lined with white doors and illuminated by a recessed skylight that washes the slatted ceiling in even light. Wooden blinds along the corridor modulate privacy and brightness, layering control into what is often treated as throwaway circulation space. Here the corridor becomes a transitional experience, a slow decompression from the sociable kitchen to the quiet bedrooms beyond.

The desk niche tucked into one of the bedrooms shows similar care. Wire-rail brackets, a simple shelf, a cane chair beside a draped window. It is a workspace designed not for productivity but for writing a postcard, reading a chapter, or doing nothing in particular. That restraint is central to the project's identity: this is a retreat, not a remote office.

The Carved-Out Terrace

The recessed central section, facing west, is arguably the smartest move in the plan. By carving the terrace out of the building volume rather than appending a deck, Sundberg creates a sheltered outdoor room that feels intimate even when the Baltic wind picks up. A slatted timber pergola filters direct sun while still allowing the long Scandinavian twilight to flood the dining table below.

Orientation matters here. West-facing means this terrace captures the last hours of summer sunlight, exactly the time a family on holiday actually wants to sit outside. It is a practical decision dressed in elegant geometry, and it gives the house its distinctive plan: a bar with a bite taken out of its middle, legible from every angle.

Why This Project Matters

Small houses get fewer column inches than museums or mixed-use towers, but they often carry heavier design obligations. Every square foot has to work, every joint is visible, and the client sleeps ten feet from every decision you made. The Yngsjö Retreat House meets that challenge without resorting to minimalism's usual trick of subtracting until only a white box remains. Sundberg keeps the warmth in: oak underfoot, larch overhead, curtains instead of blinds, a pergola instead of a solid roof. The house is precise but never cold.

More broadly, the project demonstrates how a split-level section and a single material palette can replace the heavy-handed site moves that still dominate residential architecture in scenic locations. No retaining walls, no infinity pool aimed at the sea, no oversized terrace cantilevered for Instagram. Just a timber bar lifted gently into the canopy, touching the ground only where it needs to, and framing the forest it was careful not to cut down.
