Your Brookfield home additions team

Brookfield is a regular part of our schedule. Our design showroom and office sit at 2345 S Commerce Dr, in New Berlin, an easy drive from Brookfield, and it's where every addition on this page started: a walk-through, a set of Chief Architect drawings, and a fixed-price contract before a single footing was poured. Being local means faster site visits, a showroom you can walk into without driving across the metro, and a crew that already knows the permitting process in Brookfield.

Additions that look like they were always part of the house

The difference between an addition and a great addition is how it meets the existing structure. We design rooflines, siding, and interior flow so the new space blends perfectly, visually and functionally.
From foundation to finishing details, every element is handled by one accountable team: design, engineering, permits, zoning, and construction.
Second-story additions that double space without losing yard
Kitchen and bathroom expansions that transform daily routines

We Build More than Home Additions

As carpenters, we know that you have to build a strong foundation before you can build anything else. We take that philosophy seriously and that's why we like to build strong relationships with our clients. We are honestly interested in learning about you and your home addition dreams, and your plans for your space.
We're not in a hurry to get you to sign a contract, we like to take things slow and easy. Once we've gotten to know each other, then we'll be able to work effectively together to create your dream custom addition.
Beyond additions, we also design and construct custom built homes in Brookfield, ensuring every project reflects your vision and lifestyle.
When you do one thing exceptionally well, you're considered a master of your craft. One of the major differences between us and other home remodeling contractors is that our singular focus is on interior spaces. Our design team has perfected the craft of designing home additions that compliment, enhance, and transform a home. Our team and trade partners are masters at turning high-end materials into beautiful details that result in refined luxury living spaces.
Creating luxury spaces is an art form and it takes years to perfect the techniques that produce spectacular results. All of the masters on our team have honed their skills over decades and they produce some of the most beautiful spaces imaginable. It's not just the aesthetics that make our work so memorable, we build spaces that are meant to last for years to come.
You're the kind of person who understands that the better the materials, the better the presentation. We understand this as well and that's why we always use the very best materials for every aspect of every project we undertake. We also understand that higher quality materials cost more and we're careful not to waste anything, but that doesn't mean we'll cut corners. You deserve the best and we deliver.
Every project we undertake follows our unique, proven process. That begins when you first connect with us, whether that's online, in our Showroom, or over the telephone. We ask a lot of questions and we take a lot of notes so we understand what you want and need. We'll schedule a meeting with you to get more information about your plans and ask you to bring along your own sketches, images, and ideas.
Over the course of the design phase, we'll work closely with you to work out plans for your new home space. That means we're going to ask you a lot of questions about your home, your family, how you'll use the new space, and your expectations. We will take our time to really get to know you and we'll use your ideas as inspiration as we draw up the plans. We want to ensure that everything is exactly the way you imagine it to be. Once we've got a design you love, we'll stay in constant communication and meet in person to make all of the fun decisions about things like materials, fixtures, and other details. Our entire team of trade partners will come in during this time to meet with you, and to tour your home and discuss the project. This important step allows us to accurately discuss the design plan, and the project timeline in detail.

Common Questions

Addition remodeling questions

How long does an addition remodel take?+
Most home additions run 8 to 16 weeks once construction starts. The timeline accounts for ordering and lead times, plus key milestones with updates throughout.
Will I know what my addition will look like before construction?+
Yes. You review Chief Architect drawings and 3D renderings during design and development, and key decisions are finalized before the job starts.
Who handles permits, plumbing, and electrical?+
We do. As a design-build firm, you will not need to hire a designer, architect, general contractor, plumber, or electrician separately. One team, one point of contact.
Can I stay in my home during the remodel?+
Almost all of our clients do. We set containment, floor protection, and daily cleanup standards, and use HEPA air filtration to manage dust.
