Building a custom home is more than construction—it’s about designing a lifestyle without compromise. With 35+ years of experience across Long Island—from Lloyd Harbor to Port Washington—Callahan Construction Inc. specializes in turning complex visions into masterfully crafted realities.

Why Choose Custom?

• Total Design Freedom: Every room is tailored to your specific flow, from gourmet kitchens to luxury master suites.

• Location Selection: Build exactly where you want to live, whether it’s the North Shore’s waterfront or the South Shore’s beach towns.

• Quality & Investment: Custom builds use superior materials and meticulous craftsmanship, ensuring long-term resale value in the competitive New York market.

Our Proven 4-Phase Process

We guide you through every step to ensure a stress-free journey from concept to completion.

1. Discovery & Design

We begin with a deep dive into your vision, budget, and site evaluation. We collaborate with architects to refine floor plans, window placements, and material selections until they are perfect.

2. Permitting & Prep

Navigating Long Island’s specific building codes and zoning requirements can be daunting. We handle all permit applications, environmental reviews, and site grading.

3. Construction & Systems

Your home takes shape through precision framing and the installation of high-efficiency HVAC, electrical, and plumbing systems. We prioritize weatherproofing to withstand Long Island’s unique coastal climate.

4. Final Details

After interior finishing and rigorous quality control inspections, we conduct a final walkthrough to ensure every detail meets our elite standards.

Unique Long Island Considerations

• Coastal Engineering: We utilize hurricane-resistant techniques and salt-air-resistant materials.

• Energy Efficiency: We exceed NY State codes with high-performance insulation and smart-home technologies.

• Architectural Heritage: Whether you prefer classic Colonial, Cape Cod, or Modern Coastal, we ensure your home complements the local neighborhood.

Choosing the Right Partner

The success of your home depends on your builder. Look for:

• Local Expertise: 35+ years of navigating Nassau and Suffolk County regulations.

• Transparency: Itemized pricing and clear timelines (typically 10–16 months).

• Communication: A partner who listens and provides regular site updates.
