Ryan McCarthy, founder of GC Builders, began his career in residential construction while in college and went on to take on many roles across the industry—framing, supervision, project management, budgeting, and full project coordination. That range of experience gives him a practical, ground-up understanding of how great homes are built.
Ryan is a builder at his core. He stays closely involved in every major step of each project, working directly with architects, designers, subcontractors, and clients to maintain clarity, precision, and consistently high standards.

A custom home builder manages the entire process of designing and building a home tailored to your specific lifestyle, site, and design preferences. This includes site evaluation, permitting, budgeting, architectural collaboration, construction management, and delivering a move-in ready home that reflects your vision.
Custom home timelines vary, but most projects in Greater Boston take 12 to 18 months from design to completion. Factors that impact timing include lot readiness, permitting, complexity of the design, and material lead times. Early planning with your builder is key to an accurate timeline.
Costs depend on location, design complexity, square footage, materials, and finishes. In the Boston area, high-end custom homes typically range from $500 to $1,000+ per square foot. A detailed consultation is essential to establish a realistic budget aligned with your goals.
