Services
Full-Service Architecture Firm in Wisconsin
Abacus Architects is a full-service architecture firm serving clients throughout Wisconsin. We have offices in Milwaukee, Sheboygan, Manitowoc, and Racine County, giving us a local presence across the state for clients wherever their project is located. For over 23 years, we have worked with developers, business owners, contractors, and homeowners on commercial and residential projects of every scale. Our approach is consistent: architecture, civil engineering, and interior design under one roof, one point of accountability from concept through construction, and a real commitment to your goals and your budget.
Architecture, Civil Engineering, and Interior Design: All In-House
Unlike many Wisconsin architecture firms that focus on design alone, Abacus offers three core disciplines in-house. Fewer handoffs. Tighter coordination. A smoother path from concept to construction.
Architecture
Our architects work across commercial and residential sectors throughout Wisconsin. We use advanced 3D modelling throughout the design process so you can see your building before a dollar is spent on construction, and so we catch coordination issues before they become costly on-site. From initial master planning through construction administration, our team stays with your project the entire way.
Industrial and Manufacturing Architecture
Our in-house civil engineering team manages site planning, grading, stormwater, utility design, and permitting. Most architecture firms outsource this work. Keeping civil under the same roof means faster approvals, fewer conflicts, and one accountable team for your entire project.
Interior Design
Our interior designers work alongside the architecture team from day one. From material selection to lighting and space planning, the result is a finished space that works as well as it looks and stays within your budget.
Commercial Architecture
Abacus has deep experience across the full range of commercial building types: corporate offices, industrial and manufacturing facilities, multifamily housing, education, healthcare, hospitality, and more. We understand the economics and timelines that drive commercial development in Wisconsin, and we design with that discipline built in from the start.
Residential Architecture
We work directly with homeowners across Wisconsin who want a custom home, whether that is a new build in the city, a home on the water, or a luxury residence designed around the way you live. Because architecture, civil engineering, and interior design are all in-house, you have one team and one person responsible for the outcome.
