One team. Architecture, construction, landscape design, and interior design under one roof. From your first sketch to the day you move in.
When your architect and contractor aren't on the same page, you end up making expensive compromises. Letter Four integrates both from the start, so nothing gets lost in translation.
Our founders are a licensed architect and a licensed general contractor which means from day one, the people designing your home are the same people building it. We work with homeowners across LA on custom home design, full-scale remodels, home additions, seismic retrofits and fire rebuild projects. We bring architecture, interior design, landscape design, and construction under one roof for every single client.
One team, one process, one all-in budget. No surprises.
See Our Work
Our designs are never cookie-cutter or recycled. Every home we build is customized to express your personal aesthetic, fit your lifestyle and respond to the specific conditions of your site.
Craftsman or Contemporary, Mid-century or Mediterranean, Traditional or Tudor, or something entirely new. Whatever direction you're drawn to, we guarantee it will be exclusively yours. We relish a challenge and love exploring new territory, as long as the result is something you've never quite seen before.

The Design-Build Promise
Most custom home and remodel projects in Los Angeles go sideways for one reason: design and construction are treated as two separate jobs, handled by two separate teams, with two separate interests. Letter Four was founded to fix that.
Our in-house team of licensed architects, general contractors, landscape designers, and interior designers works together from the very first conversation. Since it's one of the biggest purchases you're likely to make, we believe your all-in budget should never come as a surprise tally at the end. It should be real, transparent and accounted for from day one.
You've probably already met with other contractors or architects. Did the architects quote their fees without considering what it would actually cost to build their plans? Did the contractors give you a price-per-square-foot estimate with no design work to back it up or telling you if that is an "all-in" cost estimate?
The full picture goes beyond sketches and hard construction costs. A realistic budget for your Los Angeles home remodel or custom build also needs to account for surveys, engineering, consultants, permitting, interior finishes, and landscaping. That's before the first nail is driven.
Whatever your project calls for, we'd love to hear about it and help you chart the right path forward. Our full team works side by side through every phase, so every dime and detail is accounted for before you commit to anything.
