Your dream, our mission

New Custom Design Home

Connecticut's Premier Architectural Design Services

Architecture is more than the appearance of a building. It is the art and science of creating spaces that are both functional and beautiful. As a licensed architect with over 30 years of experience, I have worked on a wide range of projects, from small renovations to large commercial buildings. No matter the size or scope, my goal is to provide timely, professional service at a fair price. I am based in northeastern Connecticut and frequently serve clients throughout southern Massachusetts and surrounding areas. Whether you need help with a custom home design or another type of architectural project, please contact me today. I would be happy to discuss your project and provide a range of professional fees based on the services you select.

Design Consultation

Consultation Meeting

When you hire me to design your addition, I begin with a one- to two-hour consultation to understand your goals, review the proposed space, and develop a plan that fits your needs. We will also evaluate the surrounding areas, including any existing rooms or structures that may be affected by the renovation, to make sure the new addition works smoothly with the rest of your home.

Our look inside your vision

We will also discuss the estimated cost of your proposed addition or renovation within the existing home. Once you provide basic details about the type of space and location, such as a new garage, family room addition, or second-floor expansion, we can prepare drawings to help develop a feasibility budget and estimated construction costs. This allows future decisions to be based on clear, accurate information from the start.
