Helena, Montana · Since 2016
Sworharts Interiors is a five-person studio led by Mary Davis. We plan whole-home renovations, single rooms and furnishing packages — drawn properly, costed honestly, installed by trades we have worked with for years.
What we do
Most clients come to us somewhere between “we have a builder booked” and “we have no idea where to start”. Each service below is priced as a fixed fee once we have seen the space, so you know the cost of the design before anything is ordered.

Why people hire us
Sworharts started in a rented workshop on Pine Street in 2016, building furniture for neighbours. That is still how we think: a room is a set of real materials that has to survive dogs, ski boots and a decade of use.
We work with fourteen Montana trades and three regional makers. Nothing is specified that we cannot get serviced within a day's drive.
Words from clients
“Mary redrew our kitchen twice before we ordered a single cabinet, and she was right both times. Nine months of daily cooking later, nothing about it annoys me.”
Karen L. — Helena, MT · Kitchen & dining, 2025
“What sold us was the spreadsheet. Every item, every lead time, every alternate if something was discontinued. No surprises at all.”
Daniel & Rue O. — Boulder, MT · Whole-home, 2024
“We booked the two-hour consultation thinking we would DIY the rest. We ended up doing exactly that, with her notes taped to the wall.”
