Forest Run

by Senna | Sep 27, 2024

Forest Run

Out on a secluded lot in the County, Forest Run home is a peaceful retreat for retirement. The lot entices you to pull up a chair and just listen to the birds, frogs, bugs and furry critters in the surrounding forest. Once inside, you feel a sense of coziness by the warm-toned finishes, but still have a great connection to the idyllic nature surrounding the home through the large and strategically placed windows.

Unfortunately, during excavation the foundation trench became a big muddy pond due to the clay-rich soil. This resulted in many days suited up in waders and rubber boots. During the foundation pour, we made the choice to use less fly ash in the concrete mix than we would normally because of the cold temperatures and soupy ground. For context, we try to use as much fly ash as we can to reduce the foundation’s embodied carbon. But sometimes compromises have to be made in order to create a more robust structure.

Overall, Forest Run was a fun project to do, with some twist and turns along the way. We are so honored to have built our second-time client another home!

Fox Net Zero House

by Senna | Nov 28, 2023

Fox Net Zero Home

Started in the winter, building the Fox Home was not without its challenges, but the challenges ended up working in our favor in the end and producing this beautiful and unique home. Right off the bat, after we poured the concrete slab, the weather turned and frosted. As we saved the slab from freezing using plastic sheets and hay, the wind kicked up and caused the hay to come into direct contact with the slab as it was curing. The hay interacted with the concrete and caused what turned out to be really cool color undulations which add to the home’s character. Now we are intentionally adding this option for future clients who want some extra pizzaz in their concrete floors!

We always love when clients add their personal touches to a home as well, and in this case that personal touch was in the form of a repurposed trash receptacle laundry chute!

South Hill

South Hill Forest Hideaway

South Hill Forest Hideaway is placed on a one-of-a-kind lot in the heart of town yet privately tucked away in the woods with beautiful views. The forgotten lot was purchased by a couple who envisioned an accessible, aging-in-place hideaway to grow old in together, with a big emphasis on accessible. In order to achieve this dream, the home’s design and final finishes had to be carefully considered. The 1525 square foot home is all one level so that every room can remain usable and without worry about falling on stairs. In order to further fall-proof the house, the drywall and countertop corners are rounded, the flooring is made of a softer material, there is a walk-in shower with grab bars to hold on to and the washer and dryer are elevated higher off the ground. The houses most accessible bathroom was also designed to make accessing it with a wheelchair or walker a lot easier as it is 6’ wide and instead of a standard vanity, has a pedestal sink. All of the doors are 3’ wide and have lever handles which are easier to open than knobs.

Due to the lot’s topography, South Hill Forest Hideaway was built on a steep slope and required half of the house to be stilted while the other half has a slab-on-grade foundation. For some contractors, stilt houses can be tricky to build, but TC Legend Homes has plenty of experience and expertise in this kind of build.

When it came time to tackle the tree retention plan, the homeowner joined in and got their hands dirty planting the 22 Douglas Fir, Western Hemlock, Western Red Cedar and Grand Fir saplings with love and care.

This home is a truly special hideaway!
