Issaquah Rental Home

Rick had plenty of building experience, so when he decided to construct a detached accessory dwelling unit (DADU) on his large lot in Issaquah, he wanted it to be a hands-on project. TC Legend Homes built the highly insulated SIPs shell, and Rick took it from there. These photos show what an excellent job he did with the finish work. While the home does not have solar panels installed yet, it is oriented to make the future addition of PV simple.

We like this project because it shows how an owner who wants to get involved can save on construction costs and still end up with an air-tight, well-built structure that will last for generations. We also like how Rick made excellent use of his beautiful treed lot, adding another home near his main residence that will bring him rental income and add value to his property.

Montlake Modern

After more than two years of looking at dozens of houses, putting down multiple offers on several properties, and just not being able to find exactly what they wanted, Relja and Yoojin decided to build their own house. With two architects in the family, it probably wasn't very surprising.

The modern, positive-energy home they designed meets all its own energy needs while also powering an electric car. 

Both Relja and Yoojin work in the technology sector, and building their home with the most advanced materials was important to them. However, after receiving bids from other builders, they weren't sure their dream home would be within their price range. After teaming up with TC Legend Homes, they found that building with advanced materials, such as structural insulated panels (SIPs) and insulated concrete forms (ICFs), could actually fit their budget.

In keeping with the high-tech concept, the house includes the latest in home automation to further reduce energy requirements. Heating, cooling, and the LED lights are all controllable through wifi. Even the master shower has a feature that prevents the water from turning on until the desired temperature is reached. The owners are looking forward to writing their own apps to help automate the house.
