This is a 2674 square foot strawbale house with a master suite above the kitchen and dining area and a two room bedroom suite on the other side (west) of the house. It was designed both as a home for the owners and a bed and breakfast when in season. Each of the bedroom areas have their own outside access so privacy is ensured.

The owners did all the work themselves. They harvested 45 tons of earth to form the adobe interior mass walls, the earthen floors and the several inch thick stucco plaster. While they didn’t harvest the straw off their property, all the stone in the house was from their land, as is the wood for doors, trim, countertops, furniture, bookcases, and all flooring.

Windows, lighting fixtures and other materials for the house were salvaged and reused throughout the house.

ENVIRONMENTAL IMPACT
The house was designed and built with a great awareness of chemical sensitivities – the house is allergen and chemically free. They have had several guests who have been “chemically injured” and were able to feel safe in the house and its environment. Doctors are now sending their MCS (Multiple Chemical Sensitivities) patients there for a stay in a place where they can heal.

In order to be able to have people in the house who are so sensitive, all materials had to be in their ‘natural’ state. There was no concrete in the home except for the shallow foundation, lumber was harvested from beetle-kill pine on site for columns or beams, and all trim, floors, interior doors and cabinets. Recycled cellulose insulation was used for ceiling insulation. All windows reused from other buildings, many of the light fixtures were also reused from other buildings. There was virtually no construction waste.

The items with the largest embedded energy were the steel roof, the wind turbine, PV panels and hot water collectors. Virtually everything else was salvaged or reused.

AESTHETICS
Other than the domestic hot water panel on the front by the kitchen, the pv and even the wind turbine are hidden away in the trees and one has to go looking for them in order to find the source of electricity.

PUBLIC AWARENESS
The owners, since they started building the house, have regularly had people in to teach them about strawbale and renewable energy. Since the house was finished, they also regularly hold fundraisers there, to benefit the local arts league. People are invited to troop through the house (with appointments) to learn about how to build a house that is not connected to the local utility, how to build with renewables and houses made of straw can and will stand up. The owners are now extremely well know in the Valley for promoting renewables, and are often sough after for their advice. So much so, that William is thinking of becoming LEED certified because he is often giving advice he might as well get a few credentials behind him.

REPLICABILITY
Las Manos - Outside FrameStrawbale continues to catch the eyes of the public and of a few production builders.

One of their guests went back to California and built their own strawbale B and B just outside of Joshua Tree National Monument. They said that they were inspired by what they found at Las Manos.

The owners are still very committed to renewable energy and we are currently designing two strawbale cottages connected by a working greenhouse. William also says that he will be working with a “pair of vacuum solar collectors, add an 80 gallon tank that will get the heat and redirect it to the infloor radiant in the winter”.
