Building a custom home on Martha’s Vineyard or Cape Cod is a dream for many — but as anyone familiar with coastal construction knows, it’s also one of the most complex and variable investments you can make. Between design choices, permitting, logistics, and the unique demands of island construction, understanding what drives cost is essential before breaking ground.
At McElhinney Construction, we’ve spent over a decade building and managing projects across the Vineyard and the Cape. Below, we break down what you can realistically expect in 2025 when planning your new home.
Average Price Per Square Foot (2025)
Martha’s Vineyard
Standard Custom Home: $650–$850 per sq. ft.
High-End Custom or Architectural Build: $900–$1,200+ per sq. ft.
Modern or Complex Design (steel, glass, specialty finishes): $1,200–$1,600+ per sq. ft.
Cape Cod
Standard Custom Home: $550–$750 per sq. ft.
High-End Custom or Architectural Build: $750–$950+ per sq. ft.
Modern or Complex Design: $950–$1,400+ per sq. ft.
These numbers include full general contracting, project management, and finish carpentry — not just framing or shell costs.On Martha’s Vineyard, transportation, logistics, and housing for trades often add 10–20% to total budgets compared to similar mainland projects.
Key Factors That Influence Price
1. Design & Architecture
A clean, detailed set of architectural drawings is the foundation of a predictable budget. Architectural complexity — from rooflines to finishes — drives cost more than square footage alone.Tip: A coordinated design-build process prevents costly changes once construction begins.
2. Site Conditions
Coastal topography, ledge, and access all matter. Many Vineyard and Cape lots require custom foundation work, septic upgrades, or stormwater management. Even simple driveways can add cost when ferry logistics or staging are involved.
3. Material Availability
Material delivery to Martha’s Vineyard requires ferry coordination and staging, adding both time and cost. Even on Cape Cod, regional supplier demand affects pricing. Ordering key materials early (windows, cabinetry, fixtures) helps stay on budget.
4. Labor & Trade Costs
Skilled trades in Massachusetts are in high demand, and Vineyard labor rates include travel and housing premiums. Working with a company that maintains dedicated crews and trusted local subs can save both time and money.
5. Permitting & Engineering
Every town — from Edgartown to Chatham — has its own zoning and conservation requirements. Early coordination with engineers and officials keeps budgets realistic and timelines predictable.
Building for Efficiency & Longevity
Today’s coastal homes are built to higher performance standards than ever before. Energy-efficient insulation, triple-glazed windows, and advanced HVAC systems add to upfront costs but reduce long-term ownership expenses while improving comfort and durability.
What Homeowners Can Expect in 2025
A realistic all-in budget (design, permits, utilities, and construction) is:
Martha’s Vineyard: $1.5M–$3M+
Cape Cod: $1.2M–$2.5M+
Your design choices, square footage, and site complexity ultimately set the tone — but a seasoned builder will help you make value-driven decisions that align with your vision and budget.
