Small is the new green

Increasing environmental awareness along with economic and demographic trends favor smaller house sizes. Many cities are doing their part by updating zoning codes to allow cottage housing and small backyard cottages (detached ADU's) on residentially zoned lots. Seattle and Portland are two cities which allow backyard cottages up to 800 sq. ft. in size. These small houses provide opportunities for families, while increasing housing stock density and diversity.

Magnolia Family Builds a Backyard Cottage


Ben and January live in Seattle's Magnolia neighborhood and were excited when a new Seattle ordinance allowed them to build a backyard cottage behind their home.  We wanted to build a place for my father to live when he retired, so he could be closer to his grandchildren Leo and Francis. Said January.  In the near term they planned to rent the cottage and ultimately decided to use it as a vacation rental through VRBO.  This has proven to be quite successful helping fund the construction of the cottage.


In Seattle, backyard cottages are limited in size to 800 sq. ft. in size and a height of one or two floors. To create the most desirable rental unit the family chose to build a 2 bedroom, 1 bath plan.  Building a cottage involved overcoming lots of hurdles first during design and permitting done by microhouse and the construction by Carlisle Classic Homes.  While their lot met the minimum lot size and other requirements for a backyard cottage it is located in an Environmentally Critical Area (ECA)  in which  new construction prohibited except through an exemption process.  The site slope was both a benefit and a challenge.   The new cottage has nice solar exposure and a territorial view and it sits down slope from the main house providing physical and visual separation.  And while a thoughtful site design minimized excavation and use of retaining walls there were additional costs related to the ECA designation.






The steep slope of Ben and January's lot kept them from creating an accessible cottage for January's father, a common goal for those who build backyard cottages with an idea towards aging at home.  The cottage is accessed from an alley running adjacent to the cottage.  We were able to apply for, and obtain a parking waiver because of the nature of the site, this gave us a little more flexibility on the cottage placement and reduce construction cost.



Because of the small size of the cottage, the design was important.  Placement of windows and natural lighting were crucial. Although frustratingly difficult to photograph, the connection to the landscape helps make the small living room feel larger. Ben and January's cottage opens up on a patio with a nice territorial view.  The cottage is orientate with the largest windows facing south where they can get the most natural light.  The recessed porch allows winter sun to penetrate deep into the house while shading the windows during the summer months. 




"A lot of what we did was determined by what the zoning code would allow but we still had to make a lot of decisions each of which had a big impact on the overall budget." Said Ben. We had a limited budget so we chose finishes that would be durable affordable.







The north side of the house is shaded by a large fir tree.  To add natural light to the small bathroom  a skylight was used. 




Vaulted ceilings make small rooms feel larger. The scissor truss design used  is not only energy efficient, and affordable to build, but the simple gable form gave us an opportunity to play around with the overall style of the building.

drought tolerant plants: 
saving water in style

A dry summer that saw record breaking heat and drought in much of the country has come to an end. Rain and cool weather have returned to in the Puget Sound. That means the beginning of planning and planting for the year ahead.  With our summers predicted to be warmer and dryer, what can we do to create a yard that will look beautiful year round while saving water? The careful selection of native and drought tolerant plants can result in a beautiful landscape that requires minimal maintenance and water.  Read on to learn more about the use of these popular plants.


Native and Drought tolerant  plants

Native plants are often a good choice for gardens as they are well adapted to your climate and available rainfall without the use of supplemental watering after they have been established. Their use has the added benefit of creating habitats that favor local birds and other wildlife.   Lists of native plant species for your region are available from many sources one of the best of which is your local cooperative extension office.  Local and  nurseries are also a great place to see and learn about native plants.

Many Puget Sound natives are Drought-tolerant.  That means they are resistant to seasonal periods of little or no rainfall. These plants come in an amazing variety and can be used to create lush landscapes.  Here are some of our favorites.
