Great projects are built through collaboration.

At our 14,000 sf ground-up residence in Massachusetts, the framing process has been driven by close coordination between us, , and from the very beginning. Together, the team selected trim joists on the first and second floors to allow ductwork, piping, and other MEP systems to run seamlessly through the structure while maximizing efficiency and minimizing future conflicts.

The coordination goes beyond the drawings by using augmented reality technology to visualize MEP layouts before installations begins.

Swipe to maximize outdoor space ➡️

At one of our Boston townhome projects, we installed a disappearing pool. Thanks to and their Hydrofloors technology, our clients are able to not only have a pool, but also a full patio to use for entertaining.

With a push of a button, the pool floor rises and lowers to the desired depth, whether that be a full pool or a wading pool.

Happy April Fools from Sea-Dar! 😂

Our project managers least favorite call is definitely from the social media team. Jokes on them though… they thought we’d never post these moments!

They might not be content pros, but they are pros at running projects, so we’ll let it slide.

After demolishing the existing house on the property, we buikt this family compound with a 5,300 sq ft. main house, 700 sq ft. guest house, a detached garage, a pool, and spa.

This residence is noteworthy for its opposing angles and beautiful views of the ocean. These photos make us so excited for the warm summers in Cape Cod! ☀️
