Your Delafield home additions team

Delafield 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 Delafield, 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 Delafield.

Additions that look like they were always part of the house

From foundation to finishing details, every element is handled by one accountable team: design, engineering, permits, zoning, and construction.

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.
