Custom Home Construction
Custom Home Planning & Lot Evaluation
A strong custom home project starts before construction. The lot needs to be reviewed so the home can be planned around what is possible, practical, and valuable for the property.
The buildable area, utilities, access, drainage, setbacks, lot coverage, existing structures, and future outdoor space all matter. These items affect the home’s size, layout, foundation, entry points, parking, storage, porches, decks, and overall construction path.
ProCoast helps homeowners look at the property early so the home is not designed in a vacuum. Lot planning items to review:
Buildable area and site layout
Setbacks, lot coverage, and zoning limits
Utility access and drainage conditions
Foundation and elevation considerations
Outdoor living, parking, and storage needs

What Our Clients Say
Coastal Property Planning
Coastal Construction & Floodplain Planning
Building near the coast often requires more planning than a standard inland lot. Floodplain conditions, elevation requirements, drainage, foundation design, storm exposure, and long-term maintenance should all be considered early.
These details can affect the home’s height, foundation type, mechanical placement, entry stairs, storage areas, outdoor living spaces, and overall layout.
The goal is to design a custom home that works for the property, not just a floor plan that looks good on paper. Coastal planning considerations:
Floodplain and elevation review
Foundation and drainage planning
Weather exposure and material choices
Outdoor living and covered porch design
Long-term maintenance and durability
Additional Living Spaces
Custom Homes, Rebuilds, ADUs & Detached Structures
Not every homeowner needs the same kind of project. Some are building on a vacant lot. Some want to replace an older home but keep the location. Others need a guest house, garage apartment, backyard cottage, or detached structure that makes the property more useful.
The parent service is custom home building, but the right path depends on the property and the homeowner’s goals.
A new custom home may be the right fit when the lot is ready for a full build. A tear-down and rebuild may make more sense when the existing home is no longer worth renovating. An ADU or backyard cottage may solve a space problem without replacing the main house.

Frequently Asked Questions
How much does it cost to build a custom home in Lewes?
The cost depends on the lot, home size, foundation, floodplain conditions, elevation needs, finishes, utilities, site work, outdoor living spaces, and overall project scope. A property review is usually needed before a realistic budget can be discussed.
What should homeowners know before buying a lot to build on?
Before buying a lot, homeowners should review buildable area, setbacks, zoning, floodplain status, utilities, drainage, access, lot coverage, and any community or Historic District requirements that may affect what can be built.
Can ProCoast build a custom home on a vacant lot?
Yes, ProCoast can help with custom home construction on vacant lots. The lot should be reviewed early so the home can be planned around site conditions, utilities, setbacks, floodplain factors, and long-term property use.
How do flood zones affect custom home construction?
Flood zones can affect foundation design, finished floor elevation, mechanical placement, access, drainage, permitting, and construction methods. These items should be reviewed early, especially on coastal or low-lying properties.
Is it better to remodel, tear down, or rebuild?
It depends on the condition of the existing home, the cost of renovation, structural issues, layout limitations, property value, and long-term goals. If the home needs major structural work or cannot support the desired layout, a rebuild may be the better path.
Can a custom home include an ADU, guest house, or detached garage?
Sometimes. ADUs, guest houses, backyard cottages, garage apartments, and detached garages depend on the property, zoning, setbacks, utilities, parking, and intended use. These items should be reviewed before design begins.
Can a custom home be built in the Lewes Historic District?
It may be possible, but visible exterior work, demolition, new construction, and design details may need additional review. Rooflines, materials, scale, and appearance can all matter depending on the property and scope.
What is the difference between a custom home and a production home?
A custom home is planned around the property, layout needs, design goals, and long-term use. A production home usually follows a more limited set of standard floor plans and options.
When should a builder get involved in a custom home project?
A builder should be involved before design decisions go too far. Early input can help identify site constraints, construction issues, budget factors, utility needs, permitting considerations, and practical ways to build the home. As custom home builders, ProCoast helps homeowners each step of the way!
Can ProCoast help decide between a custom home, rebuild, or ADU?
Yes. The right path depends on the property, existing home, space needs, budget direction, and long-term goals. ProCoast can help homeowners compare the options before committing to a specific project type.
