This Indonesian House Turns Its Sloping Roof Into a Garden, a Staircase, & a Rooftop Pool

Some houses are designed to be looked at. Split Mass Residence, completed in 2026 by K-Thengono Design Studio, is designed to be moved through — a 712-square-metre home in BSD, South Tangerang, Indonesia, where every architectural decision is in service of movement, togetherness, and the slow pull of the outdoors.

Founder Kelvin Thengono built the project around a single, quietly radical idea: “The main design goal was to allow a seamless sequence of spaces that keeps the family connected, while also staying closely aligned with the surrounding landscape.” The house sits on a corner — what architects call a hook site condition — and rather than treat that exposure as a problem, the studio used it as the engine for the entire massing strategy. Volumes are split, pulled apart, and repositioned so that no single path through the house feels accidental.

Designer: K-Thengono Design Studio

That split is where the project gets interesting. Tiered, sloping garden roofs connect indoor living spaces directly to the planted outdoor setting, blurring the line between ceiling and garden in a way that feels more organic than architectural. From the open-plan kitchen, living, and dining area on the first floor, a glass door opens straight onto a grassy rooftop slope. An outdoor staircase continues upward to a swimming pool and barbecue area — the roof isn’t just a lid; it’s the social core of the house.

On the exterior, two materials do the heavy lifting. Concrete anchors the structure, giving it weight and presence on the streetscape. PE rattan panels wrap across the facade in woven screens that soften everything — filtering light, adding texture, and offering just enough visual privacy without closing the house off from its surroundings. The contrast is deliberate: one material says permanence, the other says warmth. Together they give the house a character that’s grounded and tactile rather than slick.

What Thengono has built here isn’t really a house in the traditional sense — it’s a system of encounters. Divided volumes, green roofs, and internal and external staircases create different scenarios for family interaction, so the architecture itself nudges people toward each other without ever forcing it. The rooftop garden crowning the whole composition reinforces that layered approach — landscape as architecture, architecture as landscape.

In a region where residential design often defaults to gated grandeur or tight minimalism, Split Mass Residence lands somewhere more considered. It’s a house that knows exactly where it wants you to be — and makes getting there feel like the whole point.

This House Splits Into Three Pieces So It Can Stay Hidden in Its Own Forest

The Curious House in Zagreb doesn’t try to win you over immediately, and that’s exactly the point. Designed by Croatian studio FORVM arhitektura, it’s a family residence perched on a steep hillside, slightly pulled back from the main road and swallowed by dense urban vegetation — orchards, spruces, pines, cedars. The house doesn’t announce itself. It settles in.

Rather than drop a single mass onto the slope, FORVM broke the program into three distinct elements, each responding to a different register of the site. It’s a compositional decision that reads as both pragmatic and poetic, dissolving the usual tension between building and terrain into something more like a conversation. The topography shapes the architecture. The architecture shapes how you live inside it.

Designer: FORVM

The ground floor is fully glazed — a deliberate move to keep the resident in constant dialogue with the world outside. Green cascades past the glass. The tree canopies filter sunlight and block sightlines, doing the work that walls might otherwise do. Privacy here isn’t enforced by opacity; it’s offered by nature. The forest earns its place as an active participant in the spatial experience, not just a backdrop.

The upper floor shifts register. Where the ground level opens up, the upper volume turns more inward, more considered. Roof windows cut directly to the sky, and through them, tree silhouettes remind you again that you’re inside a forest. The building keeps finding ways to return you to the landscape — not through grand gestures, but through quiet architectural moves that accumulate into something genuinely atmospheric.

From the outside, the Curious House plays a different game. Its smooth, reflective surfaces don’t reveal the interior so much as they absorb the green world around it. You expect transparency; instead, you get a mirror. The observer looks for signs of life within the envelope and finds it harder than the glazing might suggest. It’s a house that hides in plain sight.

Designed by Dinko Uglešić, Ina Vlahović, and Marijana Rančić, and photographed by Bosnic+Dorotic, the Curious House exemplifies a strain of European residential architecture that takes landscape seriously — not as an amenity to be framed, but as a logic to be followed. FORVM, founded in 1991 by Ante Uglešić, has long worked within the specifics of Croatian terrain and climate, and that attentiveness shows here in every decision, from the fragmented massing to the calibrated relationship between glass and canopy.

A Chilean Architect Quietly Built a House That Follows the Hill Instead of Fighting It

House 22, designed by Chilean studio Loft7 and completed in 2023, sits on a sloping coastal lot south of Punta de Lobos — a stretch of Chilean coastline known for dramatic surf and untouched native scrubland. The lot descends toward the northwest, and rather than resisting that gradient, the architecture follows it, letting the terrain pull the building naturally toward an uninterrupted view of the Pacific Ocean.

At 320 square meters, the residence is generous without being excessive. Loft7 structured the build using a combination of reinforced concrete and steel frames — a technical pairing that allows the house to hold its ground on a challenging slope while keeping the interior language warm and tactile. Exposed timber beams run through the living spaces, the dining area, and the kitchen, grounding each room in material honesty. There’s no attempt to disguise how the building is put together. That transparency is the design.

Designer: Loft7

What makes House 22 worth studying isn’t a single dramatic gesture — it’s restraint applied consistently. The interiors lean on wood, natural light, and sightlines that always resolve at the ocean. No surface fights for attention. The beam grid overhead becomes rhythm rather than decoration, and the open-plan social spaces feel like they’re orientated by the view rather than by a floor plan. Spaces breathe because the architecture got out of the way.

Pichilemu is famous in surfing circles, but architecturally it’s a place where the Chilean coast has quietly been producing some of the country’s most considered residential work. Loft7 fits that lineage — a studio that has built its reputation around sites where nature already has the upper hand. Their approach with Casa 22 trusts the land and the light, deploying materials that age well in a coastal climate and a massing that reads modestly from the outside while delivering on every expectation from within.

Photographed by Fabián Acuña, the project looks different at every hour of the day. Morning light hits the timber and fills the interiors with warmth; the Pacific turns silver in the afternoon. That relationship between material, orientation, and time of day is never accidental in good coastal architecture — and here it feels entirely intentional. House 22 isn’t trying to be the loudest house on the Chilean coast. It’s trying to be the most honest one. On both counts, Loft7 delivers.
