Deborah Berke discusses a house addition she designed for artist Peter Halley in Columbia County, New York on a mostly wooded 100 acre site. Determining that the existing house had integrity that did not allow for a simple add-on, she decided to build the addition on another part of the site and connect it to the house with a row of trees. The three primary components of the house are a studio space, guest quarters, and a screened porch. The screened porch is not normal in that area but was insisted upon by the client’s wife. Each of the three programmatic components is its own building but are combined as a unit.
