How It Works

From initial ideas to detailed construction drawings, we help you plan your home and prepare for the building permit process.

01

Consultation

We start by listening to your ideas, learning what matters most to you, and discussing your property and timing to help you understand the next steps.

02

Schematic Design

We develop floor plans, exterior elevations, and 3D renderings to help you see how rooms connect and how your home will look. Together, we refine the layout, rooflines, and exterior details before moving into construction drawings.

03

Construction Documents

We prepare detailed drawings for your project’s agreed scope, giving your contractor and building department clear information for construction planning and permit review.

04

Permit Support

We help address building department questions about our drawings and clarify design details during permit review. The support included in your project is outlined in your design agreement.

What Our Clients Say

After a devastating fire destroyed our home, leaving only the foundation, we knew we wanted to rebuild. We loved our property and couldn't imagine living anywhere else, but we wanted to take the opportunity to transform our contemporary home into a more traditional New England Colonial. The challenge was achieving that vision while working with the existing foundation. Custom Structure Designs embraced the challenge and created a beautiful design that was exactly what we had envisioned. They helped us turn a devastating loss into an opportunity to build the home we had always wanted.

Joe C.

Fire Rebuild, Plainville CT

Custom Structure Designs helped us create a beautiful new master bedroom suite at the rear of our home. One of my biggest concerns was making sure the addition would blend naturally with the existing house rather than look like an afterthought. Mike listened to what we wanted and carefully designed the addition to complement our home's existing style and character. The end result exceeded our expectations. The new space gives us everything we were looking for, and the addition blends in so seamlessly that it looks like it has always been part of the house.

Master Suite Addition, South Windsor CT

From the beginning, Mike took the time to sit down with me, listen to my ideas, and understand what I wanted in my new home. Rather than simply drawing up plans, he worked closely with me throughout the design process, offering valuable suggestions and practical solutions that helped bring the vision to life. He paid attention to the details, made sure the layout fit my family's needs, and was always willing to explore ideas and make adjustments. What stood out most was his personal involvement and genuine commitment to getting everything right.
