Take a look at the primary bathroom we finished over on McClellan St in Passyunk Square. We made this smaller footprint bathroom feel huge with the curbless shower s floor to ceiling tiling. Check out all the pictures on our website sites project page, 1118 McClellan.

A recent bathroom addition we completed over on Clymer St in Bella Vista. This was originally unused space on the third floor, and is now the primary bathroom connected to the primary bedroom. We love the way this one turned out!

Check out this rendering we created of the bathroom at our Poplar St project in Northern Liberties pre-construction, and swipe to see how it turned out after we finished construction. Working with a design/build company on your project means a more accurate, cost effective design that translates into a viable space

Swipe to see the messages behind the drywall from 1978! So many of these Philadelphia row homes are old time capsules, you never know what you’re gonna get (we haven’t seen cash buried yet unfortunately). These houses have seen generations of Philadelphians reside and less them down in the family. That’s why we love what we do!

Which style of addition do you like the best?

Very exciting to see this project finally come to life! Was a challenging process to secure permits with zoning, historic, and survey obstacles but we prevailed and broke ground early April and finished framing in July!
