See Your Home Before It’s Built.

A home should be experienced before it’s constructed. We help homeowners make confident design decisions through thoughtful architecture, interiors, and realistic visualization—before construction begins.

Arch Design by B is a collaborative online residential design studio serving homeowners and contractors.

The studio

Thoughtful residential design, without the guesswork.

We work with homeowners who are ready to invest in clarity—before construction starts, before materials are ordered, before costly changes on site. Our process replaces overwhelm with coordinated full design you can experience, refine, and carry into the next phase of your project.

Philosophy

Design it right the first time.

A home is imagined long before a foundation is poured. When layout, structure, and interiors are designed in isolation, the result is friction—change orders, compromised rooms, finishes that never quite fit. We design the whole home as a single decision, so what you build matches what you envisioned.

How it works

From first conversation to completed full design.

01

Discovery

Share your site, goals, and budget. We confirm fit and scope—whether you start with a discovery call or go straight to your package estimate.

02

Design

Layout, architecture, and interiors develop in milestones. You review, refine, and approve at each stage—with clarity at every step of the design.

03

Full design deliverables

Coordinated architectural and interior design documentation—drawings and visuals that capture your home as designed, structured so they can be developed into a build-ready set when you and your project are ready.

Client stories

Real homes. Real clarity.

Homeowners across the U.S. come to us when they want a plan they can trust—not another Pinterest board.
