Why Design-Build?


Most custom home headaches come from the gap between the architect and the builder. We close that gap. With Iron + Branch, your designer and your builder are the same team — one point of contact, one shared vision, and a budget aligned from day one.

  • One team, start to finish — no miscommunication between design and construction
  • Budget clarity early — detailed cost breakdowns before ground breaks
  • Fewer surprises — design decisions made with real construction costs in mind
  • On-time delivery — an integrated process keeps your project on schedule

Quality HousBuilt for Coloradoes

We design homes that fit Douglas County — the climate, the terrain, the light, and the local building codes. That local expertise means smarter designs, faster permitting, and a home built to last in Colorado conditions.


Our Process

  • Consultation — We listen. Your vision, your lifestyle, your budget, your timeline.
  • Design + Agreement — Detailed plans and a transparent scope of work, priced before we build.
  • Construction — The same team that designed your home builds it.
  • Final Walkthrough — We don't hand over the keys until it's exactly right.

What Our Clients Say

Homeowners consistently tell us the same three things: the communication was clear, the craftsmanship exceeded expectations, and the project finished on time.
