Home Additions, Renovations & Custom Home Designs in Niagara & Southern Ontario
Additions & Renovations Designed for How You Live
We design home additions, interior reconfigurations, and exterior transformations throughout Niagara and surrounding areas.
Every project begins with measured drawings of the existing home and results in permit-ready construction plans designed to integrate new space seamlessly with what’s already there.
Thoughtful planning. Clear documentation. Designed to be approved.

With over 7,500 residential designs completed across Ontario, our team brings deep experience to every project; especially additions and renovations.
Clients often tell us they appreciate how responsive, approachable, and supportive our team is throughout the design process.
Our drawings are designed not just to look good, but to work in the real world of construction. Builders regularly tell us that Nauta plans are among the clearest and easiest to work from, helping projects move smoothly from design to build.
