Here are the key components
involved in a Westchester
home addition:

Feasibility study & planning

We assess your property’s zoning restrictions and structural limitations, ensuring your addition is legally compliant and structurally sound before moving forward.

Permitting & approvals

Westchester’s permitting process varies by municipality, with some areas requiring architectural board review on top of standard approval. We handle every step, ensuring your project moves forward smoothly.

Architecture & design

Our architects design cohesive additions that blend seamlessly with your home, considering local zoning while enhancing natural light, optimizing layouts, and increasing property value.

Foundation & framing

Site preparation is crucial for stability. We clear the site, lay a solid foundation, and frame the structure to establish the shape and structural integrity of your new space.

Roofing & exterior construction

We install durable roofing and exterior finishes, such as siding or stucco, that blend with your home's style. Materials are selected for their durability against Westchester’s weather, ensuring long-lasting protection.

Openings & insulation

Chapter ensures your home addition is well-protected from Westchester’s climate with proper insulation, waterproofing, and high-performance windows and doors. Our solutions enhance energy efficiency and durability year-round.

Electrical, plumbing & HVAC

We update and extend your home’s systems to support the new addition. This includes adding electrical wiring, plumbing lines, and HVAC systems to provide a comfortable, efficient living space.

Interior finishes & flooring

Interior finishes bring your design vision to life. We install drywall, paint walls, lay flooring, and add trim, ensuring the addition complements the existing home while enhancing comfort and style.

Quality assurance & final inspections

Once construction is complete, we conduct thorough quality checks and manage all inspections. Chapter closes out permits and guarantees that your addition meets all codes and is built to your satisfaction.

Popular home additions in Westchester

In-law suites & ADUs

Popular in Westchester for multi-generational living or rental opportunities, accessory dwelling units (ADUs) require specific permitting but add versatility and long-term value.

Second-story additions

Perfect for growing families or maximizing vertical space, adding a second story can double your living area without increasing your home’s footprint, which is common in towns with lot size restrictions.

Single-story extensions

Ideal for expanding living rooms, kitchens, or creating open-plan spaces, single-story extensions are a popular choice in Westchester, especially in homes with larger lots.

Sunrooms & four-season rooms

Sunrooms offer a bright, airy retreat, while four-season rooms provide year-round comfort with insulation and climate control. Both enhance natural light, living space, and home value.

Garage conversions & extensions

Converting or expanding a garage into a living space or a home office is a smart way to add functional square footage, often with fewer zoning hurdles.
