Exterior, House Building Type, Shed RoofLine, and Mid-Century Building Type With post-and-beam construction, a thin roof profile, and an open floor plan that facilitates an interplay between the interior and exterior, the Dwell Prefab Palm Springs by Turkel Design bears all the signatures of the architecture firm. The show home is its first in California, which allowed Turkel and his team to put extra emphasis on indoor/outdoor living.  Photo 2 of 4 in Dwell x Turkel Design: Breaking Ground in Palm Springs
