Craftsmanship at Every Stage
From the first sketch to the final walkthrough, Castro Construction & Design handles every phase of your custom home — under one roof, with one team.
Custom Home Building
Your vision. Our craft. Zero compromises.
We build fully custom homes from the ground up — no floor plan templates, no cookie-cutter finishes. Every Castro home starts with your family's lifestyle and ends with a structure built to outlast generations. We self-perform the critical trades and vet every subcontractor personally, so quality is never left to chance.
- Site evaluation and lot preparation
- Custom architectural plans
- Foundation through final finish
- 10-year structural warranty
Design-Build Process
One team. One vision. No miscommunication.
Most builders hand you off to a separate architect, then a separate contractor — and the gaps between them cost you time, money, and sleep. Our integrated design-build model keeps design and construction under the same roof. Your project manager knows the blueprints as well as the architect does, because they helped create them.
- In-house architectural design
- 3D renderings before breaking ground
- Material and finish selection guidance
- Seamless design-to-build handoff
Project Management
On schedule. On budget. No surprises.
A dedicated Castro project manager is your single point of contact from permit to punch list. They coordinate every trade, track every milestone, and give you transparent weekly updates — so you always know exactly where your home stands. Fixed-price contracts mean the number we quote is the number you pay.
- Dedicated project manager assigned at contract
- Weekly progress reports and site photos
- Fixed-price contracts, no hidden costs
- Milestone-based payment schedule
