Custom in-ground backyard pool with stone deck and modern lighting at twilight
Backyard Pool

A pool — and the entire backyard around it.

Most pool builders stop at the coping. We design the pool and everything that touches it — deck, lounging, shade, planting, lighting — so the whole space feels like one finished project.

Deciding on who to work with for a significant pool and landscaping project is never without its risks. Will the project be completed on time and on budget? Will it exceed expectations? Will the process be smooth, and most importantly, fun?

Tom and his team replaced our retaining wall, or what was left of it ( very old! ). From the start we felt comfortable with Tom and his vision of the final product. His team was hard working all day and clearly have a great working

Overview

Built right the first time.

We design and project-manage the full backyard pool build — pool shell, coping, deck, fence, landscape, and lighting. One point of contact from concept to first swim.

Frequently asked

Good questions, straight answers.

How long does a pool build take?+

From shovel in the ground to first swim is typically 8–14 weeks depending on the design, fencing requirements, and weather. Permits can add time on the front end.

Do you handle the pool shell, or just the landscape around it?+

We manage the full project — pool, equipment, coping, deck, fence, and landscape. You get one schedule, one point of contact, one finished result.

Will my yard be a disaster zone during the build?+

Big pool builds disturb a lot of ground — that's reality. We protect what we can, stage materials cleanly, and restore the rest as part of the landscape finish.
