Pool Terraces in Marion, Massachusetts.

We would rather explain the number than defend it. In Marion, the swing factors are access, excavation depth over sandy coastal loam over till, drainage, and protection of what is already growing on the property — the stone itself is rarely the deciding line.

You get an itemized scope after we walk the property — what is included, what is not, and where the money actually goes. No allowances that quietly become change orders halfway through.

The coping is the one line everyone reads, from the water and from the house. We set it dead level to the shell with consistent overhang, and choose thermal bluestone or granite for grip underfoot — matched to the white Federal captains’ houses and shingled harbor estates of Marion so the pool reads as part of the garden, not a hole cut into it.

Seat walls, steps, and planting beds get designed into the surround from the start, whether the property sits in Marion Village, Sippican Harbor, and Converse Point or anywhere else in town.

A pool surround is the hardest-working stone on a Marion property — wet feet, furniture, chlorine, and a New England freeze-thaw cycle all at once. Because the land here is sandy coastal loam over till, turning to peat and marsh at the water’s edge, we excavate to depth and confine a compacted base under the whole terrace, then pitch it so water runs away from the pool shell and the house.

That base is why the coping stays true and the joints stay tight. Pool decks almost always fail at the edges, where backfill settles and nobody confined the base — on a harbor village wrapped in salt marsh and low coastal woods on Buzzards Bay, that is exactly where we spend the extra day.

The part nobody photographs: where the pallets sit, where the excavator tracks, and what the property looks like on a Friday afternoon. In Marion we plan all of that up front and hold the schedule we gave you at the start.

Designers keep sending us South Coast work for one reason: what gets built matches what was drawn. We hold the spec, raise conflicts early, and document as we go — including on the Jonathan Keep Landscape Design projects throughout this portfolio.
