Let’s Talk About Your Addition
Every home addition starts with constraints: your lot size, setback requirements, where the existing mechanicals run, and how the rooflines can connect. Before we talk budget, we need to understand what’s actually possible.
- What space do you need and how will it connect to your current layout?
- What’s the best location on your lot given zoning and setbacks?
- How do we match the addition to your existing architecture?
- What foundation type makes sense for your property?
Start With a Conversation
The first step is a consultation at your home. We’ll walk the property, discuss what you’re trying to accomplish, and give you a realistic sense of scope and timeline.
