Zenith Design + Build

Zenith Design + Build is a custom design-build firm founded in 2018 by Nicholas Donlin, serving the Des Moines metropolitan area of Iowa. The company offers a full spectrum of design and construction services, with a dedicated focus on custom tiny homes and accessory dwelling units.

Zenith builds custom tiny homes so homeowners can downsize without compromising on quality. Their ADU services encompass in-law suites, granny flats, and backyard cottages on existing properties. The company manages every phase in-house, from initial design through construction completion, with typical project timelines of 4–8 months.

As of April 2026, Zenith Design + Build serves the Des Moines metropolitan area, including West Des Moines, Indianola, Adel, Waukee, Ankeny, and Polk City. The company has an award-winning portfolio of ADU and custom home projects. A completed tiny house project in Des Moines is featured in their public portfolio.
