Wine-country poise. Beach-cruiser ease.
Cool hues, airy materials, and a quiet rhythm. Soothing, serene living for the West Coast pace.
Iconic design, expertly curated.
The visionary spirit of the 20th century. Bold colors, retro details, and the optimism that made the era unforgettable.
Curated chaos, beautifully composed.
A blend of eras, cultures, and materials. For homes meant to reflect a person, not a trend.
Every package pulls from the proven combinations our team has built before. The selections work together. The decisions are already pressure-tested.
Thousands of finishes narrowed to combinations that hang together. You choose a style, not five hundred individual items, and your designer fills in the rest.
Each package is curated from real Letter Four projects. The fixtures, finishes, and palettes have already been specified, ordered, installed, and lived in.
Swap items within the same quality tier, customize at the level that fits your project, and keep the cohesion that comes from a tested palette.
Same curated designs. Same trade access. Three ways to bring the package home, depending on how much you want to manage yourself.
Self-implementation
The complete design package. Mood boards, palettes, physical samples, and a downloadable spec list with vendor sourcing. You handle ordering and installation with your contractor, at your own pace.
Designer-supported
Foundation plus a dedicated designer in your corner. A Notion-based project hub, contractor-ready specs, and a quantity calculator. You still manage ordering, but you are not doing it alone.
Full-service, white-glove
Comprehensive design support, team-led sourcing, and end-to-end management. We order, track deliveries, coordinate vendors, and handle approvals while keeping you involved on the creative calls that matter.
Every package covers the surfaces and selections that define how a home looks, lives, and lasts. Specified by the team, sourced through our trade network.

Yes. Each package is curated for cohesion, but you can swap items within the same quality tier without losing the design integrity. If a finish is not quite right for your taste or your space, we help you find an alternative that still works with the rest of the palette. Foundation gives you the spec list to work from. Studio adds occasional designer check-ins to support those swaps. Signature handles the full customization in conversation with you. The shorter the leash on customization, the lower the risk of drift away from a tested combination.
Design materials are delivered within two to three weeks of kickoff. That includes the mood boards, the specification list, and the physical material samples sent to your home. Procurement timelines depend on the items you select and the service level you choose. Foundation puts the ordering pace entirely in your hands. Studio gives you tools and check-ins to manage the timing. Signature includes order management, delivery tracking, and vendor coordination handled by our team.
If a specified item becomes unavailable, we provide a comparable alternative at no additional cost. The substitution keeps your project on track and the design intact. Because each package draws from materials we have used on real Letter Four projects, we already know which finishes pair well with which alternates. That makes substitutions a small adjustment, not a design redo.
No. The discovery call exists to help you figure that out. Many homeowners arrive with a Pinterest board, a few rooms they love, and a vague sense of what they do not want. We work backward from there. By the end of the call, we will have narrowed the six styles to a clear direction and identified which service level fits the scope and pace of your project.
It does not have to be. Letter Four offers interior design as a standalone package, but our interior team works inside the same firm as our architects and our licensed general contractor. That means we can specify a kitchen knowing exactly what will work with the existing plumbing, or design a primary suite knowing how the structure behind the walls will support it. If construction work is part of your project, the design and the build can come from one team rather than two.
Three quick signals. Foundation fits homeowners with a contractor they trust, time on their hands, and the desire to handle ordering themselves. Studio fits homeowners who want a designer in their corner but plan to manage procurement. Signature fits homeowners who want the design selected, sourced, ordered, tracked, and installed without the project landing on their plate. The discovery call resolves the question quickly, often by looking at how busy your calendar is rather than how big your home is.
A 30-minute discovery call. A style read, a scope read, and a clear recommendation. No commitment beyond the conversation.
