Bridgehampton and Sagaponack, Specifically
Houses Built to a Cap.
Sagaponack is where the Town of Southampton learned to limit house size: the 64,000-square-foot main house at Fair Field, finished in 2003, prompted a townwide cap on single-family homes. The village incorporated and writes its own zoning; the ZIP code's median sale price reached $8,075,000 in 2023, the first time the country's top two ZIP codes both passed $8 million.
Behind the dunes the risk is water. After FEMA remapped the area, the number of Sagaponack homes in the flood plain rose from 46 to 119, a change local officials tied partly to beach erosion. Our designs put the rack, the transfer switch, and the outdoor electronics above the flood line and the generator through the Town's permit.
01 · Shore
Above the Remapped Flood Line
With more than twice as many Sagaponack homes now mapped in the flood plain, equipment placement is a design decision: racks above grade, transfer switches and outdoor electronics above the base flood elevation, marine-grade fixtures outside.
02 · Distance
One System Across the Fields
Farmland estates spread a main house, a guest house, a pool pavilion, and a gate across the land. Fiber between them, planned with spare conduit before the drive goes in, lets one Lutron and Crestron system run all of it.
03 · Permits
The Town's Paperwork
The Town of Southampton and East Hampton require their own home-improvement contractor licenses beyond Suffolk County's, and the Town's electrical permit has a generator line. We plan the filings with the licensed electrician from the start.
At a Glance

Bridgehampton and Sagaponack, Answered
Who installs Lutron and Crestron systems in Bridgehampton and Sagaponack?+–
Cave Group does. We are a Crestron Elite Gold Partner and Lutron Gold Dealer with an office in Long Island City, and our Hamptons work includes a Southampton waterfront residence completed in 2024. We work across the South Fork from Westhampton to Montauk.
What changes for an oceanfront house behind the dunes?+–
Everything outdoors becomes marine-grade, and everything electrical moves above the flood line. FEMA's remap more than doubled the Sagaponack homes in the flood plain, so the rack, the transfer switch, and outdoor electronics sit above the base flood elevation and the conduit is planned with the elevation in mind.
Can one system cover the main house, the guest house, and the gate?+–
Yes, and it should. We link the buildings with fiber, give each one a small equipment location, and run them as one Lutron and Crestron system, so keypads, touchscreens, and the app work the same way everywhere. It is far easier to do while the site work is open than after the fields and the drive are finished.
How do you keep the house running when we are not there?+–
With monitoring and redundancy. Cave Watch watches the network, the control system, audio-video, and lighting around the clock and fixes most faults remotely; central-station alarm monitoring and live guard video monitoring stack on the same plan. The network carries a second connection, often Starlink, and the rack sits on battery backup, so a winter outage does not leave the house dark to us.
What internet is available in Bridgehampton and Sagaponack?+–
Across much of the East End, Optimum is the only wired provider and there is no Verizon Fios. We confirm what reaches the address, and we design the network with Starlink or a second carrier as automatic failover, so the cameras, the remote access, and the house itself survive a cut.
