NEST DADU Options Dec 1.Indd

URBAN NEST

Crafted from prefabricated wood panels, this versatile DADU serves as garage /workshop and/or home. The 600 SF footprint NEST sits against the rear setback of standard 4,000/5,000 SF lots with a 200 SF loft above. Designed for PassiveHaus detailing, NEST is a highly sustainable, lower-carbon built home.

A garage entry is vehicular entry or an outdoor eating/living area - raising garage door for shelter. As garage, NEST becomes workshop, with sleeping area above. The main entry can be the garage, or, side door facing the primary home connecting visually.

Options include: larger 800 SF footprint; master bed area replacing entry door area; different NEST geometries. Construction options include prefabricated cross-laminated-timber panels or building light-wood frame. Both include inexpensive slab-on-grade and grade beams.

living simply in the wooden nest, surrounded by smells and textures of natural materials, the sleeping nest above reveals a clerestory open to sun and moon.
