Abstract Residential Design + Build unifies design and construction so you get clarity, cost confidence, and uncompromising craftsmanship across Boise and the Treasure Valley.
A home that reflects your life and legacy, crafted with high‑level execution and thoughtful design. Whether you favor modern farmhouse, traditional, or mountain modern, you want a builder who can translate vision into permits, drawings, schedules, and a home that is delivered on budget.

Most custom builds go off the rails for the same reasons:
We solve these problems with a true design‑build model and detailed pre‑construction planning that leads the project, not the other way around.

You get one integrated team with designers, builders, and project managers working in sync from day one.
Our clients begin the journey excited and end it relieved because the plan was clear, the numbers were honest, and the build stayed under control.
From first sketch to final walkthrough, we design and deliver high‑performance custom homes tailored to your lifestyle. Our process integrates architectural design, selections, and construction sequencing to minimize surprises and keep momentum high.
Ideal for: New builds on prime lots, relocation builds, second residences, estate homes.
Add valuable living space with a seamless addition or an income‑producing ADU. We align structure, utilities, and finishes with your existing home or create a striking contrast when that’s the brief.
Ideal for: Multi‑generational living, guest suites, studio/office, rental income, caretakers.
In‑house design means fast iteration, disciplined detailing, and cost‑aware decisions. We coordinate permitting and engineering while guiding selections to prevent decision fatigue.
Deliverables include: Concept design, code review, permit set, engineering coordination, selections road map, and pricing‑ready construction docs.

We listen first. Goals, budget, site, timelines, and how you’ll live in the space.

We lead a structured design and pricing effort, including drawings, engineering, selections, vendor quotes, and a buildable schedule, so the numbers are real and the path is clear.
We build with weekly updates, proactive site walks, and tight cost control. Final walkthrough and punch are documented, then we stand behind the work with a third‑party warranty.


Pre‑construction isn’t paperwork, it’s how you avoid budget creep and delays. Before we break ground, you receive:
The result: fewer change orders, faster decisions, and a smoother build.

Different projects call for different approaches. We offer both Fixed‑Price and Cost‑Plus agreements.
Best when scope and selections are fully defined. You get a single contract amount tied to an agreed scope and specifications.
Best for longer or more complex builds where future pricing may fluctuate. You see every invoice and markup, and you only pay actual costs.
We’ll guide you to the model that best protects your goals and risk profile.


Building from another state? We excel at projects where the owner is remote.
You’ll always know what’s happening, what’s next, and what needs to be decided.

Choosing the wrong builder can lead to stalled projects, busted budgets, and even legal disputes. The most expensive home is the one that doesn’t finish

Brad is top notch. Great communicator, attention to details. His company even sponsored our Recreational Flag Football team. He's active with the community and an inspiration. His calm demeanor and easy going, which will put you right at ease. He's even pretty witty and great to talk too. I would highly recommend him for any and all your design and construction needs.

Brad with Abstract Residential Design + Build has been great to work with, he always communicates before the job starts and as it progresses. His jobs are organized and always ready when I show up. I would highly recommend him for anyone looking to build or remodel their home.
Lucas Rushin
Great people! They care more about doing what’s best for people than just making money. I asked them to modify and finish up some plans I’d started with another draftsman a few years back. He spent time with me, gave me valuable feedback suggestions and then told me as much as he would love to help, it would be best for me to use the original draftsman and explained all of the reasons why. Class act. Appreciate the integrity.

Yes. Our architectural team works hand‑in‑hand with construction and interiors, which speeds decisions and ensures drawings align with budget and buildability.
We invest heavily in pre‑construction: complete drawings, early selections, locked‑in sub pricing, and a procurement plan. You’ll see a line‑item budget before we mobilize.
Weekly meetings, Job Tread for real‑time updates and approvals, scheduled site walks (virtual when needed), and documented decisions keep you in control from anywhere.
We frequently deliver modern farmhouse, traditional, and mountain modern, and we’re fluent in tailoring details to your taste and site.
We’ll recommend the model that best matches your scope and timeline. Fixed‑price favors well‑defined projects; cost‑plus (open‑book) is ideal for longer builds with variable markets.
Yes. In addition to our closeout package, we register a third‑party Maverick warranty that’s transferable, offering added protection.

Abstract- a detailed, high‑level execution, and a great team guiding your project from first sketch to final key handoff.
