4x8 Construction is a full-service design-build firm — and the rare builder that self-performs its own structural concrete and hardscape. One contract, one team, from homesite to finished home.
CSLB #840735 · Licensed & Insured · 20+ Years Building in San Diego County
What We Do
Three ways to build with us.
Full-Service Design-Build
Custom Homes
Ground-up custom homes, ADUs, and major remodels — planning, permits, and construction managed under a single contract, from first sketch to final walkthrough.
Structural concrete for general contractors and custom-home builders: footings, stem walls, structural slabs, and retrofits — bid from your plans, built to pass first inspection.
Patios, walkways, driveways, decks, and outdoor living spaces — engineered wall systems and finish concrete that turn a yard into livable square footage.
No mystery, no runaround. Here's exactly how a project moves through our hands.
Consult & Estimate
We walk your lot or your plans and deliver a free, all-inclusive line-item estimate. You see every number.
Design & Permits
We coordinate architects and engineers, finalize plans, and carry them through city approval.
Build
Our crews pour the foundation and build up from it — with scheduled trades and a jobsite that stays clean.
Deliver
Walkthrough, punch list, warranty. We close out completely — paperwork included.
Why It Matters
The builder who pours the foundation.
Most builders sub out the structure of your home to the lowest bidder. We're the opposite: structural concrete is where we come from, and our own crews still pour every foundation we build on.
Structure done in-house — the part of the home you never see, done by the people whose name is on the contract.
One contract, one team — design, permits, and construction under a single agreement.
Transparent numbers — line-item budgets, not allowances that balloon later.
Owner-run — you talk directly to the person responsible, every time.

20+ Years in San Diego County
Two decades of foundations, homes, and hardscape across the county — from hillside lots in Poway to coastal remodels in La Jolla.
Self-Performed Structural Work
We don't broker out the critical scopes. Foundations and concrete are our own crews' work — the trades other builders subcontract to us.
Transparent Line-Item Budgets
Every estimate is itemized. You know what each scope costs before we start, and progress billing tracks against it as we build.
Our Divisions
Specialized crews, one standard.
Two of our service lines run as dedicated divisions — same company, same license, crews focused on one thing.
Outdoor Living Division
Sol Hardscapes
Patios, walkways, pavers, decks, and complete outdoor living spaces for homeowners and landscape designers — built with the same structural discipline behind every 4x8 project.
Right-of-Way Division
SD Sidewalks
Sidewalk repair and replacement across the City of San Diego — city-notice responses, permits, and inspections handled end-to-end for property owners.
Both divisions operate under 4x8 Construction Inc. · CSLB License #840735
