While the original home was dark, like other homes of its period, the addition allowed Andrews and his team to let in an abundance of natural light.

The façade of the interwar dwelling was painted bright white and left largely unchanged, with a sole burst of color coming from a yellow DesignByThem “tomtom” letterbox. Though the extension is invisible from the street, architect Christopher Polly says it provides “significant additional freedom for the owners and their three young children to grow into.”

Landis Gores, a fellow member of the Harvard Five, collaborated with Johnson about the finer details; the two would picnic on the site.

This is what I cannot do without a drop ceiling, but is vaguely the style I am going for.

ICON developed its Vulcan I 3D printer over a period of about two years. The gantry-style printer on rails is mobile and weighs about 2,000 pounds.

The original home’s second floor had three bedrooms with flat ceilings. Arch11 quickly realized there was a great volume in the upper floors at the gable ends of the home and chose to integrate the attic space into the second floor. This design move allowed the interior to be informed in part by the exterior while creating a bright, serene living space among the treetops.

In this glass-enclosed master bedroom, a LC4 armchair faces the master bed. The moveable frame adjusts along the base, allowing the sitter to switch from upright to full recline, or lounge at a number of other sitting angles.

Thanks to the extension’s vaulted ceiling, the master bedroom and minimalist staircase have views of the sky. Polly admits to having sacrificed floor area so that the full-height stairwell could achieve a stronger connection with the outdoors. Toyo Ito Mayhuma pendants hang from the ceiling, accentuating the space’s dramatic height.

In one of the three bedrooms, Wright designed a built-in desk and graphic chair. The angular windows and skylights are continued into the bedrooms.
