Lightness and solidity, exposure and retreat. On the easternmost reaches of Waiheke Island, a house occupies the crest of a ridgeline - permanence in an otherwise shifting landscape.

Above the Pacific coastline of Costa Rica, pavilions unfold around a garden and connect beneath a single floating roof. Nature becomes the pathway, guiding movement between views of ocean, forest, and sky.

Set at the edge of a clearing for the photovoltaic array that powers the main cottage on the site, Cardwell Clubhouse is an off-grid hybrid building that is part utility and part leisure hub. Designed by Dubbeldam Architecture + Design for an outdoors-oriented family who spend much of their time on the site immersed in nature and active pursuits, the clubhouse functions as the site's central social and activity hub. It combines a multipurpose clubhouse room – doubling as a flexible guest suite – with a garage that stores outdoor leisure equipment for activities like racquet sports, cross-country skiing, snowshoeing, and more. An adjacent outdoor court for tennis, basketball, and pickleball (created in the clearing necessitated by the solar array), along with areas for bocce, horseshoes, and children's games, reinforce the clubhouse's role as a destination for gathering and play.

On the slope above the Krkonoše village of Strážné, a timber log cottage once stood. It was swallowed by the era of mass recreation, along with respect for ownership, craftsmanship, people, objects, and nature. The original house was concealed beneath layers of alterations, extensions, and makeshift additions, poor repairs, and artificial panel cladding. Unfortunately, almost nothing of the original cottage remained worth saving. The small amount of preserved original structures was, for the most part, in poor technical condition. Rather than merely preserving its material substance, the aim therefore became to rediscover the spirit of the house.

Cultural centers continue to serve as a productive ground for unbuilt architectural exploration, reflecting how architects are rethinking the role of public institutions in relation to landscape, experience, and program hybridity. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of proposals that expand the definition of the cultural center beyond a singular building. These works position architecture as a spatial framework that mediates between research, exhibition, retreat, and public life, often embedded within or distributed across natural and urban contexts.

The house is located on a wide plain by the coast of the North Sea. An old log house forms the core of a new detached house for a young family with small children.

Japanese architect Kengo Kuma and his studio Kengo Kuma & Associates (KKAA) have unveiled Earth | Tree, a site-specific installation at Copenhagen Contemporary, developed in collaboration with Danish wood manufacturer Dinesen. Opened on March 28, 2026, as part of the institution's CCreate programme, the project occupies a former industrial hall, introducing a spatial intervention defined by timber, brick, and light. Led by partner Yuki Ikeguchi, with team members Asger T. Taarnberg, Nicolas Guichard, and Yasemin Shiner, the installation marks

"The landscape in Karen carries a quiet density, and the studio is conceived as something that settles lightly into that condition. The ambition was to create a space that holds both introspection and production, where material, light and structure move with a certain restraint. The building draws from archetypal African forms as a way of thinking about permanence, climate and memory. It is a place where making unfolds slowly, in dialogue with its environment." David Adjaye

A team led by French architecture practice Coldefy, comprising CITYFÖRSTER, Sporaarchitects, TREIBHAUS.LAND, and Marko & Placemakers, has won the competition to design a masterplan for Rákosrendező in Budapest. The project is developed for the Budapest Capital Asset Management Centre, acting on behalf of the Municipality of Budapest. The design outlines a 15-year scheme to transform a brownfield site long regarded as the city's "rust belt," located on the eastern side of the Hungarian capital. The regeneration plan includes over 10,000 apartments, new transportation links, and commercial and civic spaces, forming a comprehensiv

Building above water means doing away with a part of construction that is quite literally the basis of most of our built environment: the foundation. In a world dominated by water, currents, and shifting levels are variables that simply cannot be ignored, which is why the most emblematic feature these projects share is their adaptability.
