Recalling the tobacco barns and covered bridges of New England, this handsome rowing centre on the Charles River is clad in composite wood-resin panels and louvres rendered in subtly varying geometric cuts. They are operable by simple chain pulls to control light and ventilation gain; the mechanism also syncs with the geothermal heating and cooling system to make the boathouse an efficient, comfortable year-round facility. A second, smaller pavilion is clad in glass shingles. aw‑arch.com
