A Home Addition Creates Increased Space for Issaquah Homes


AtStringham Custom Homes, we are a home addition contractor that ensures you have all the space you need to enjoy living in your house.

In most cases, a home addition is put on the back of the house. The increased space from a home addition means fewer accidents.

A home addition means you can entertain more guests and guests can even sleep over, which increases the resale value of your home.

It also means fewer allergies and diseases because there will be no cramped spaces where cockroaches, rats, and other vermin can breed, and there will be free air circulation (note that indoor air quality in a normal home is up to 100 times worse than outdoor air quality).
