MUJI Harvard Square Brings New Life to a Brutalist Landmark

Retail stores often take a more-is-more approach, filling their spaces with an overwhelming array of goods, so when one has just the right combination of products and aesthetic appeal, it can give the retailer an edge. That’s what MUJI in Cambridge, Massachusetts, banked on.

In North America, the Japanese company is evolving from a purveyor of stationery into a full lifestyle retailer. For its new location in the Greater Boston metropolitan area, Mapos Architects, in collaboration with ACTWO Architects, was tasked with renovating the Design Research building in Harvard Square—in just 10 weeks.

When the Design Research building opened in 1969, it served as a showcase for architect Ben Thompson’s shop, which included European and Scandinavian housewares. For the MUJI revamp, the architects took a deliberately light-touch approach, revealing rather than replacing the building’s defining architectural elements.

“We uncovered the existing textures to leverage what was already there and bring back the original beauty of the space,” says Colin Brice, co-founder and partner at Mapos Architects.

With a lightness not typical of the period, the structure boasts a balance of concrete and glass curtain walls, forming a jewel-box-like setting that feels surprisingly contemporary and welcoming.

“It’s really an exceptional example of Brutalist architecture and how open it can be,” explains Caleb Mulvena, co-founder of Mapos Architects and partner in charge of the project. “The entire storefront opens to the community, and customers can start shopping from the street as they look in.”

Enhancements begin at the entry, where brick flooring retains its patina, complemented by upgraded lighting and ceilings. Concrete columns, concrete masonry walls, and floating staircases were exposed to add character to the interior. White and gray tones are paired with accents of green and MUJI’s signature red. Accent walls made of locally sourced heart pine introduce warmth and align with the brand’s commitment to sustainable reuse.

Set across four levels, the 12,000-square-foot store encourages easy movement through an expansive, emporium-like layout. In the top-floor café, shoppers will find a robot barista, introducing a hospitality-inspired experience that reflects MUJI’s growing emphasis on stores as destinations rather than simply places to shop.

“It was really about leaning into the space as we found it,” Mulvena adds. “By keeping our touch light, we were able to celebrate these features.”

It is this simplicity, rather than ostentation, that makes the greatest impact. As the first step in MUJI’s broader North American evolution, the Cambridge location demonstrates how thoughtful restoration can reinforce a brand’s identity.
