The Carl’s Way residence by Lemmo Architecture & Design is an undulating, zero-energy home nestled into a gently sloping grassy site on Martha’s Vineyard. The house consists of three separate living structures and a detached garage that are connected by a large deck and dynamically sloping standing seam metal roofs. The architecture firm is now based in Austin, but formerly worked in Cambridge, Massachusetts, where Ryan Lemmo was the project manager and design lead for the Carl’s Way residence while working at Maryann Thompson Architects.
The low-lying shingle-style house is long and narrow—natural cooling occurs when the many sliding glass doors are opened to the elements.
Lighting is primarily LED to conserve energy.
The windows are high-performance triple-pane European units that ensure that the entire envelope performs as well as the highly insulated walls do.
The house is super insulated, with a full 3” wrapper of rigid insulation around all walls, roofs, and foundations. All the insulation allows the house to use a much more efficient heating and cooling system.
Although this is a house with lots of windows, they are all located under big exterior overhangs or high inside near the ceiling so that there are never any direct hits from the sun.
The open living area is in the center of the house.
The decks are extensions of the interior living space.
The HVAC system of this all-electric home is made up entirely of highly efficient Mitsubishi Mini Split heat pumps to serve both heating and cooling.To balance this high electric demand, enough high efficiency solar panels are installed out of sight on the garage to completely supply all the power needs of the home.
The profile of the house follows the silhouette of the waterway.
Big overhangs are a theme in this house; the ceiling of the dog trot is basically an overhang that extends from one side of the house to the other. It’s been popped up slighting to add dynamic rhythm to the roofline.
