Construction has started on Sluisbuurt 1B in Amsterdam!

We collaborated with .eu on Sluisbuurt 1B, a mixed-use residential building in Amsterdam's new Sluisbuurt neighborhood on Zeeburgereiland.

Conceived as a “stacked neighborhood,” the project brings together 228 apartments, of which 80% are dedicated to social housing, alongside a community center, work units, retail, shared amenities, and public spaces. Three residential volumes rise above an active double-height plinth, with brick color, façade rhythm, and detailing giving each part its own character.

Above the plinth, residential clusters support different ways of living. Family homes are located near the courtyard and outdoor play areas, homes for older residents are placed along generous galleries and a shared living room, and apartments for young professionals and single-person households connect to the collective roof garden and shared indoor spaces.

Shared spaces are placed along the building's natural routes, creating easy points of contact close to home while preserving space for rest and retreat.

Together, these residential and public spaces allow Sluisbuurt 1B to offer more than affordable housing: they support a community that can grow alongside the new neighborhood.

Not a flat ceiling in sight!

Great progress on the assembly of KJ Den Haag's double-curved timber ceiling, inspired by the city’s coastal dune landscape. Due to the ceiling curving in multiple directions, turning it into a buildable system required a project-specific design logic. The surface was mapped like topography, with isolines projected across it to make the geometry readable at full scale.

KJ Den Haag will become a new gateway to The Hague, introducing a new entrance hall for the central station, with two residential towers above, linked by a ‘green valley’ between them. On ground level, the square will include landscaping by .la, a new restaurant pavilion, and a more fluid connection to Koekamp Park.

What place does manual making still have in a digital world?

To celebrate , we are collaborating with .gallery on a very special sixth edition of Beyond Buildings, exploring what happens to our relationship with materials, process, and space when speed, ease, and automation increasingly influence how we create.

Multidisciplinary artists and designers Audrey Large and Lorena Rode join award-winning filmmaker and moderator Niki Padidar for a conversation on staying connected to process rather than simply consumption, exploring how artists and designers can continue to claim space for connection and hands-on work today.

With Audrey's latest exhibition FLOWSTONES and curated works by Lorena Rode on view all evening, the night invites you to listen in, look around, and connect with others across art, design, architecture, and beyond.

Construction has started on The Ark in Amsterdam!

This timber residential building is designed for future-oriented living, with an emphasis on residents' well-being. Located in Overhoeks, the project forms part of a rapidly growing district in the north of Amsterdam.

The Ark comprises 125 apartments and uses a cross-laminated timber structure that stores carbon, reduces the building’s environmental footprint, and enables faster, more efficient assembly. Visible timber surfaces bring warmth and tactility to the interior, qualities often associated with comfort and emotional well-being.

Full-width balconies wrap around the building and its two distinct façades: a lively street frontage with a welcoming entrance and publicly accessible terrace, and a quieter waterfront side with access to a communal garden. A central entrance hall links both sides and forms the social heart of the building.
