UK architects Ullmayer Sylvester designed the plywood-and-pine Summerhouse at the rear of an elongated Victorian garden in North London; the budget was £35,000. The light-filled structure functions as an artist studio, garden shed, table tennis venue, and kids' hangout; an 8-meter-long swath of mirror foil installed along the doglegged north side elevation reflects the foliage and helps the structure disappear into the landscape; the polycarbonate ceiling panels filter light from above.
