You know what you like when you see it, and you also know that getting there means an endless amount of decisions: The equivalent of a part-time job you didn't sign up for. If redoing your home feels overwhelming because of all the choices and styles out there, you're not alone. Letter Four’s interior design packages let you decide how much of the legwork you want to take on. That means fewer open-ended choices, and more forward motion toward a space that feels like home. This isn't a stripped-down version of full design service. It's the same curated eye and the same finish quality our design build clients receive, just packaged so homeowners in Los Angeles, Santa Monica, Culver City, the surrounding areas, and beyond can move at whatever pace fits their project.

What Do Letter Four's Interior Design Packages Actually Include?

‍

‍Every package starts with a choice of six design styles: Modern Spanish, Warm Modern, Traditional Spanish, California Coastal, Mid-Century Modern, and Eclectic. Each one is fully worked out across the rooms and surfaces that actually shape how a home lives, not just how it photographs.

For a bathroom, that means the vanity, countertop, tile, plumbing fixtures, and hardware are all specified. For a kitchen, it’s the cabinetry direction, countertops, backsplash, appliances, and lighting. Flooring and tile are mapped room by room, and exterior finishes cover paint, stucco, and hardscape. You'll also get physical material samples delivered to your home, that way you're choosing based on what a finish actually looks and feels like in your hand.

What makes these interior design packages move faster than starting from scratch is that none of it is theoretical. Every combination has already been specified, ordered, installed, and lived in on a real Letter Four project. That narrows thousands of possible finishes down to a set we already know works together.

What's the Difference Between Foundation, Studio, and Signature?

‍

All three service levels work with any of the six design styles. What changes is how much of the process Letter Four manages and how much you handle directly.

Foundation — Self-implementation
You get mood boards, palettes, physical samples, and a downloadable spec list with vendor sourcing. This one's a great fit if you already have a contractor you trust and the time to manage ordering and installation yourself.

Studio — Designer-supported
You get everything in Foundation, plus a dedicated Letter Four interior designer, a Notion-based project hub, a quantity calculator for room dimensions, and access to our trade discounts. You're still placing the orders, but you're not doing it alone.

Signature — Full-service
This is where we take the process off your plate. Letter Four places and tracks orders, handles vendor correspondence, and manages approvals, with trade discounts averaging 25 percent. You stay involved in the creative decisions that matter most, and we handle the rest.

How Long Does It Take to Receive an Interior Design Package?

‍

‍

No matter which service level you choose, you'll have your design materials, mood boards, spec list, and physical samples in hand within two to three weeks of kickoff. What changes after that is how ordering happens.

With Foundation, the ordering pace is entirely up to you. With Studio our team shares tools and check-ins to help you stay on track. If you decide to go with Signature, the Letter Four team handles order management and delivery tracking directly, so the pace is set by us instead of by how much time you have to chase down vendors.

‍

Can You Customize a Package Once You've Chosen a Style?

‍

Each package is curated for cohesion, but that doesn't mean it's locked in stone. Items can be swapped within the same quality tier without losing that cohesion. If a finish doesn't feel right for your taste or your space, we'll help you find an alternative that still works with the rest of the palette.

With Foundation, you get the spec list and make those swaps yourself. Studio adds designer check-ins to support you through the decision. Signature is where we handle the full customization directly, working it out in conversation with you.

Is Interior Design Separate From Construction at Letter Four?

It does not have to be. Letter Four offers interior design packages as a standalone service, but the interior team works inside the same design-build firm as the architects and the licensed general contractor. That means a kitchen can be specified with full knowledge of the plumbing behind the wall, or a primary suite designed with an understanding of the structure supporting it. For homeowners whose project includes construction, the design and the build can come from one team instead of two.

Frequently Asked Questions

Editor Note: Add FAQ schema (JSON-LD) to the CMS page for the questions below.

What's included in a Letter Four interior design package?

Every package covers the surfaces and selections that define how a home looks and functions: vanities, countertops, tile, plumbing fixtures, and hardware for bathrooms; cabinetry direction, countertops, backsplash, and appliances for kitchens; pendants, sconces, and statement lighting throughout; flooring and tile specified room by room; and exterior finishes including paint, stucco, and hardscape. Physical material samples arrive at your home so you can see and touch the palette before committing. The scope is the same across all three service levels of these interior design packages. What changes between Foundation, Studio, and Signature is how much of the ordering, tracking, and vendor coordination Letter Four handles versus what you manage yourself.

How long does it take to receive a design package?

Design materials, mood boards, the specification list, and physical samples, are delivered within two to three weeks of kickoff regardless of which service level you choose. What varies after that is procurement. Foundation puts the ordering pace entirely in your hands, so timing depends on your contractor's schedule. Studio gives you a Notion-based project hub and designer check-ins to help manage timing yourself. Signature includes full order management and delivery tracking, so the pace is set by the team rather than by how much time you have to chase vendors. All three paths start from the same curated interior design service levels, just with different amounts of hands-on management.

Can I swap materials within a package once I've chosen a style?

Yes. Each interior design package is curated for cohesion, but items can be swapped within the same quality tier without losing that cohesion. If a finish does not fit your taste or your space, Letter Four helps find an alternative that still works with the rest of the palette. Foundation gives you the spec list to make those swaps yourself. Studio adds occasional designer check-ins to support the decision. Signature handles the full customization in direct conversation with you. The shorter the leash on changes, the lower the risk of drifting away from a combination that has already been tested on a real project.

How do I know which service level fits my project?

It usually comes down to time, not budget. Foundation fits homeowners who already have a contractor they trust and want to manage ordering themselves. Studio fits homeowners who want a designer's support but are comfortable handling procurement. Signature fits homeowners who want the entire process, sourcing, ordering, tracking, and vendor coordination, off their plate. A 30-minute discovery call usually resolves the question quickly, often by looking at how full someone's calendar is rather than how large the project is. All three service levels draw from the same six curated interior design styles.
