Homes Designed for Coastal Living
The qualities that make coastal areas such compelling places to live also create unique demands for the homes built there.
Wind, salt air, moisture, and severe weather can act on a coastal home far more persistently than one farther inland, while local building and environmental requirements often add another layer of complexity.
A well-designed coastal home accounts for both from the first sketch, so that the rooms facing the water stay comfortable in February and the envelope protecting them is still performing decades later. At ZeroEnergy Design, architecture and mechanical design happen under one roof, so the envelope and the systems that heat, cool, and ventilate the home are designed together from the start rather than reconciled once the design is fixed.
Waterfront home design starts with the site
In Massachusetts, construction near coastal banks, dunes, and wetlands is reviewed by the local Conservation Commission under the Wetlands Protection Act. In Rhode Island, the Coastal Resources Management Council has jurisdiction along the shoreline, and Maine and New Hampshire each regulate development within their shoreland zones. Before design work begins, these reviews establish the setbacks, buffers, and elevation requirements that determine where a house can sit on its lot and how large it can be.
We work through those constraints at the outset, so that the design you commit to is one that can be permitted without being redrawn. Within them, the house is placed and oriented for the particulars of the site: the direction of the prevailing wind, the path of the sun across the lot through the year, and the views worth organizing the plan around.
Flood resistant home design, planned from the start
Much of the New England shoreline lies within a FEMA flood zone, and the maps are revised periodically as conditions are reassessed. Raising the living spaces, keeping mechanical and electrical equipment above the flood line, and specifying materials that tolerate occasional wetting are far simpler to design in from the beginning than to add afterward.
Renovations raise a further question. Under the National Flood Insurance Program, when the cost of improving a house in a flood zone reaches 50 percent of its market value, the entire building must be brought up to current flood requirements, including elevation. Knowing where your project stands relative to that threshold before drawings begin can change its scope considerably, and in some cases it makes rebuilding the more sensible choice. At Mt. Hope Modern in Portsmouth, Rhode Island, the house stands on an engineered flood-resistant foundation, with continuous insulation and triple-pane glazing in the envelope above it.
Modern coastal architecture that holds up to the weather
Our coastal homes pair clean, contemporary forms with materials that have proven themselves along the New England coast for generations. Cedar shingles and standing-seam metal roofs, for example, are not only characteristic of the region but weather predictably in salt air and harsh coastal conditions.
Much of what makes these homes durable, however, is hidden from view. Stainless-steel fasteners resist corrosion from salt air, while cladding installed over a drained rainscreen allows wind-driven rain to escape and the wall assembly to dry. Exterior mechanical equipment is selected specifically for coastal exposure, and an exceptionally airtight building envelope helps eliminate drafts, improve comfort, and keep interiors noticeably quieter during storms. Our Chatham Marshview House on Cape Cod, for example, tested at just 0.3 ACH50, half the air leakage permitted by the Passive House standard.
Selected coastal work
Gloucester Beachfront
Nestled on a beachfront site, this home provides incredible ocean views from three sides of the house while maximizing privacy from neighboring properties. With minimalist and inviting furnishings and thoughtful outdoor connections, the home allows for an appreciation of light, form, and the natural beauty of the site.
pEUI: 1.5kBtu/sf/yr
Air Leakage: 0.48ACH50
Truro Modern Beach House
Designed for a narrow, environmentally sensitive site on Cape Cod, this modern beach house balances expansive water views with ambitious energy performance. A flexible two-part plan allows much of the home to be shut down when not in use, while a high-performance envelope, efficient systems, and solar power minimize its year-round energy use.
pEUI: 11.2kBtu/sf/yr
Air Leakage: 1.8ACH50
Dartmouth Oceanfront
This modern ocean home achieves style, comfort, and aging in place within a challenging coastal New England setting. The combination of the stunning location, exceptional comfort, low operational carbon footprint, and the practicality of being able to age in place created the homeowner’s “forever home.”

Questions about building on the coast
-
Look for built coastal work on sites comparable to yours, and ask how permitting went on those projects: which boards reviewed them, what conditions they imposed, and how long approval took. It is also worth asking when the architect addresses flood elevation, setbacks, and Conservation Commission or CRMC review; because those questions determine what can be built, they should be settled before design begins.
-
Yes. Homes are built in FEMA flood zones along the New England coast every year, but the zone designation sets specific requirements for how high the lowest floor must be, what type of foundation is allowed, and which materials can be used below the flood elevation. The distinction between zones matters. In a VE zone, where breaking waves are expected, the house generally has to sit on an open foundation such as piles or columns, while an AE zone allows a wider range of approaches.
-
In most cases, yes. Building above the required elevation, known as freeboard, adds relatively little to construction cost; a FEMA-commissioned study put it at roughly 0.25 to 1.5 percent of construction cost for each additional foot. Because flood insurance premiums generally fall as a house sits higher relative to the flood elevation, the savings often offset that cost over time.
-
Cedar shingles and fiber cement are the two most dependable choices. Cedar weathers to the silver-gray long associated with the New England shore and needs some maintenance over the years, while fiber cement holds its finish with less attention, which can suit a house that is not occupied year-round. Either performs well installed over a drained rainscreen with stainless steel fasteners, a detail that matters at least as much as the choice of material.
-
The term generally describes houses that combine the simple forms and generous glazing of contemporary design with the materials and proportions traditionally used along the coast, such as shingle siding, standing-seam roofs, and plain gables. In a well-designed example, the glass is oriented toward the water rather than spread evenly around the house, and materials are chosen for how they will weather as much as for how they look when new.
