The Week's Find: The Grass House in Anacostia

• January 26th 2023

Back in 2019, an accessory building in Anacostia made history as the first code-compliant bamboo building on the east coast. Today, UrbanTurf takes a closer look at the unique structure. 

The property -- designed by BLDUS for use as an office, guest house or art studio -- sits on the a lot with a 19th century Victorian. Bamboo makes up the structural frame and parts of the interior walls of the 750-square-foot accessory property. While this is not the first property to be built using bamboo, BLDUS used bamboo panels from BamCore, which was the first American company to offer a code-compliant product.

In order to achieve LEED Platinum status, the building also used materials such as sheep's wool, mycelium, cork and various kinds of wood including cedar, cypress and willow. The sheep's wool was used for insulation, while cedar and cypress boards make up the exterior side paneling. Many of the overhead light fixtures were designed using mycelium, a fungal structure. 

The lowest level of the bamboo building consists of a large conference room with built-in wood shelving, exposed wooden beams, large below-grade windows, overhead lighting and interior stone walls. Thicketed willow branches serve as a divider up two sets of stairs and Anacostia-sourced mulberry and walnut were used to make the stair handrails and treads. The middle floor offers an entry and a kitchenette area with a sink, cork flooring and cabinet storage. The top floor acts as a loft and includes built-in desk space with wooden planked walls. 

Nicknamed the Grass House, the building plays on the name of the Glass House, which was designed by Philip Johnson in New Canaan, CT and is known for its glass walls.

"The Grass House references the Glass House while bringing natural materials to the forefront and featuring a general transparency of material sourcing rather than fixating on literal transparency," BLDUS architect Andrew Linn said.  

To make use of natural resources, the house also collects rain from the roof foundation drainage which is in turn used to water the surrounding sloped garden. 

"The Grass House is intended to question what 'clean' and 'healthy' can mean in architecture today and in the future—for humans, for other species, and for the Earth," Linn said.
