01The master plan

Drawn to scale. Built to it.

From the French doors to the woods: one master plan, drawn in three stone directions. One sheet for each direction — the layout stays; the stone, its pattern and its border change.

02Three directions

One space. Three characters.

Each shown in stone we have actually laid. Edgar brings real samples of all three to the property.

Natural Flagstone

Every stone shaped by hand to meet its neighbor. The most natural of the three — an estate that looks grown out of the land.

03The elevation · Sheet E-1

How it rises from the pool.

The retaining wall and the grand stair as you will see them from below — fieldstone, thermal caps, and stone piers with their lanterns.

04Beneath the stone · Sheet S-1

The part you never see. The part that decides.

Every direction is built the same way beneath the surface: a reinforced, drained base, every stone bedded in mortar, the surface pitched away from the house.

05From here

From this page to the last joint.

Your Design Commission fee is credited in full toward the project.

01

You choose

Approve a direction on this page — or ask for a revision.

02

The proposal

A fixed price, the scope, approximate dates and your warranty — in writing, for signature.

03

Your place in the schedule

Signing reserves your dates. Most stone is set from spring through fall.

04

The build

Built in phases over one season, with dates in your proposal. Edgar on site; the yard left clean every evening.

05

The walkthrough

We walk it together. Five years on the stone, ten on the base — transferable.

06Your decision

Choose the stone. We’ll take it from here.

Approve a direction and Edgar prepares your proposal for signature. Not quite right? Ask for a revision — one round is part of the commission.

Rather talk it through? Call or text (202) 525-7884.

Luxury isn’t loud. It’s built right.
