This week on Dezeen, La Sagrada Familia Foundation announced that Antoni Gaudí's landmark church in Barcelona is finally set to be completed in 2026.

The foundation told news site CNN that construction on the church, which began in 1882, is set to finish in two years, 100 years after the death of its architect.

Work on the church's final six towers, the last phase of the building, is now progressing.

Also in Barcelona, we spotlighted the city's rapidly growing supply of social housing as part of our Social Housing Revival series.

Barcelona's "best projects are being done in the field of social housing", local architecture co-operative Lacol told Dezeen as part of the feature.

Continuing our Social Housing Revival series, we interviewed retired Scottish architect Kate Macintosh who is celebrated for her housing schemes in south London including Dawson's Heights and Macintosh Court.

"I think that social bonding and a sense of belonging and mutual recognition is the key to a healthy society and a balanced mental outlook," she told us. "This increasing isolation that people feel – it's so sad, so miserable."

In design news, sportswear brand Camper released a modular trainer formed of six components that can be easily assembled and disassembled.

It was created as "a minimal shoe with a minimum environmental impact", allowing customers to assemble and disassemble it themselves.

Also in design, Samuel Ross revealed his first toilet designed for bathroom brand Kohler, which is set to debut at Milan design week next month.

Named Formation 02, the smart toilet is bright orange and has an asymmetric shape designed to recall brutalist architecture.

Popular projects this week included a house extension in London with a butterfly roof, a colourful house in LA designed by SelgasCano and Diego Cano and a skyscraper informed by a stack of magazines.

Our latest lookbooks featured minimalist bathrooms with peaceful pared-back interiors and compact garden studios with neat storage solutions.
