You could say we have a reputation for green building expertise and spectacular design – but we prefer to let our work speak for itself. We are dedicated to all those homeowners in search of a new home full of design, imagination, and make-you-swoon features. No doubt, Sussex will create the new home of your dreams (and of your neighbors’ dreams). At Sussex Construction, we are known leaders in the building industry. We combine good taste and getting things done with exceptional results. Because it is not just about what you build. It’s how you build it. All this without burning a hole in your pockets. If you are searching for new custom home builders in Helena, MT your search is over!

"We are one of a handful of new construction purchases (within the last year). During the build process, they were great to work with. Once we closed, all that changed. We have to run space heaters during the winter months (a brand new home) due to the design of the ductwork and Sussex wouldn't lift a finger, we have flooding at the entrance to our property, and once again, Sussex did nothing. We had fixtures in the wrong place, and some were not what we ordered at all, and guess what? they did nothing!!.. As we began to speak with others in the community, we learned of a horrible reputation throughout Helena, as well as, a horrible place to be employed. All in all, stay away from Suxxit construction at all costs. Money is their motivation, not happy families"

Home Building questions, answered by experts

Contractors may require a down payment before they begin a project—especially for those that require a lot of materials. Check with your contractor to see how much they require up front before signing a contract, but they should not ask for more than 50%. Never pay in full before work begins.

The number of rooms a guest house should have really depends on your needs. A small guest house might only need one bedroom, a bathroom, a living room, and a kitchen. Larger units may have multiple bedrooms and bathrooms. Your local building codes may limit the number of rooms or square footage you can have in a guest house.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.
