Your Build One Step at a Time
1
Consultation & Design Planning
We start by learning your vision, goals, and priorities. From lot selection and layout preferences to style, budget, and timeline, we gather everything needed to design a home that fits your life—and we coordinate with architects and engineers to bring it to paper with clear plans and 3D renderings.
2
Permitting & Site Prep
Once plans are finalized, we handle all permitting and approvals to keep the project compliant and on schedule. We then prepare the site with excavation, grading, and foundation work, ensuring a stable, code-compliant base for your new structure.
3
Structural Buildout
This phase covers framing, roofing, siding, and the installation of core mechanical systems. Our team builds the shell, installs windows and doors, and runs plumbing, electrical, and HVAC—laying down the essential structure and infrastructure of your home.
4
Interior & Exterior Finishes
With the structure sealed, we install insulation, drywall, cabinetry, flooring, lighting, paint, and fixtures. We also complete exterior work like patios, walkways, and landscaping. Every detail is executed with quality materials and a sharp eye for design.
5
Final Review & Handover
After inspections and quality checks, we walk the space with you to review the finished product. Any last details are addressed before handoff—giving you a completed home, ready for move-in.
1
Discovery & Planning
We begin by listening and understanding your goals, whether it’s more living space, a guest suite, or a second story. We assess the existing structure, explore layout options, and develop a plan that fits your home, budget, and long-term needs.
2
Design & Permitting
Our team works with architects and engineers to create detailed drawings and renderings. Once approved, we handle all permitting to ensure the addition meets building codes and HOA requirements, with no delays or guesswork.
3
Site Prep & Structural Work
We prep the build site, handle demolition or foundation extensions, and begin framing the new structure. This phase includes installing walls, roofing, and connecting the addition to the existing home with full structural integration.
4
System Installs & Finishes
Mechanical systems like electrical, plumbing, and HVAC are extended into the new space. We then install insulation, drywall, flooring, fixtures, and finishes that match—or intentionally upgrade—your existing interior.
5
Final Walkthrough & Completion
After inspections and final detailing, we walk through the finished space with you, confirm functionality, and deliver a fully integrated addition that looks and feels like it’s always been part of your home.
