Sweeney Architecture is the design component of Simplus Systems. We are a full-service design-fabricate-build partner offering rapid, fire-resilient, smoke-free, and energy-efficient building solutions for communities recovering from wildfire.

Our Simplus Building System combines non-combustible MgO prefabricated panels with Passive House design principles and proprietary innovations. This results in faster construction, lower operating costs, enhanced safety, better health, and longer-lasting buildings.

While we support projects of all sizes, Simplus is especially effective in larger-scale recovery and development efforts—multi-family housing, core infill sites, and community-wide planning. We help communities rebuild stronger, safer, and more sustainably— reducing the costs, time, and effort required— all without compromising quality, reliability, or client satisfaction.

Whether you're building a single home or planning a community-wide recovery, Simplus Systems is ready to help lead the way forward.
