Garden House

In Portland Waechter Architecture maximizes allowable Accessory Dwelling Unit space by dramatizing classic pitched-roof house typology for the Garden House.

Wood: a key resource for south tyrol

In this northern Italian region, wood is a vital resource that brings together tradition, the economy and environmental protection. The short and sustainable supply chain is worth €1.3 billion and involves thousands of local companies.

For this house-in-a-backyard, otherwise known as an Accessory Dwelling Unit (ADU), the architecture firm Waechter Architecture took Portland’s increased density movement and used it as an opportunity to explore housing iconography, sculptural forms, dual-purpose elements, and explore how to massage small space regulations in order to maximize useable space.

Garden House’s exaggerated eaves cantilever 3 meters on both sides of the house creating protected outdoor spaces below and two generous ceiling height bedrooms (and a second bathroom) upstairs – all while staying within Portland’s maximum allowable height for ADU’s. Emphasizing the sculptural quality of the house, these gutter-less eaves are also detailed with formed metal to attain a “knife-edge” profile. Rain falls from this drip edge to a rock garden below.

The client’s existing home is a 1940’s Cape Cod style house. The City of Portland requires that ADU’s match the existing house details such as the roof pitch, window proportions and siding material. The design of Garden House matches these, but re-imagines them into a unique form, as opposed to simply being a copy. This new structure has the iconic silhouette form of a “house” yet is abstracted into a distilled and pure sculptural form.

Garden House materials include regionally procured maple plywood paneling and cabinets on the ground level.
