Site Description
FEATURES: Design Innovation, Indoor Air Quality, Small Building Footprint 

This petite backyard cottage has been created from a former garage, which was a super efficient way to keep construction costs down for a one-bedroom tiny home. The collaborative team of LD Arch Design and Envision Remodels worked with a highly involved and creative homeowner to maximize the green and cozy features on a tight budget, including a hybrid heat system with a ductless heat pump supplemented by efficient infrared cove heaters supplied by Mighty Energy Solutions. This is a great stop if you have an existing garage you are thinking about converting – you can hear about our “lessons learned.” But it also has some good design options for anyone with a small space or tight budget, and even includes barrier-free design elements to allow for aging in place. 

Key green features:
•    Efficient heating systems – ductless mini split heat pumps and efficient infrared cove heaters
•    Some “tiny house” sized appliances – compact refrigerator, washer/dryer, and dishwasher
•    Sustainable, healthy interior finishes – engineered eucalyptus flooring
•    Energy efficient light fixtures – LED disk lights and Solatube with integrated lighting
•    Good insulation, air sealing, and windows – including tapered rigid insulation over the existing concrete slab (to level the former garage floor)
•    Green stormwater management – roof drains to rain garden
