"So, we were interested in how the two different architectural styles would work together." The old Edwardian home can be seen in the center of the frame, through the dining room and kitchen of the addition. Merbau Decking extends into the garden, which became the focal point of the home.

The addition’s polished concrete floor and white cladding extend into the garden, drawing occupants to the serene rear porch. There, they can relax on stools designed by Alvar Aalto and Charles Wilson while admiring the luscious greenery.

The extension not only succeeds in creating a working home for a family of five, but compellingly combines the old stone cottage with the contemporary belvedere.

"We wanted to create transparency through the house—everything under the ribbon becomes glass," said Andrews. The enormous amount of glass achieves the desired openness, a connection between indoor and outdoor, and that natural light. But it also helps to keep the addition from overwhelming the original home and accentuates the feeling that the addition is an echo. "At night, the addition becomes a glowing lantern in the back of the home," Andrews said. Arch11 put in a tigerwood deck around the expansion and the homeowners took on all landscaping. The welcoming effect at night is soft and understated but surprising by its very existence.
