Batter up, and that’s a wrap!

As the baseball and T-ball seasons come to an end, River Birch Builders wants to shout out all the amazing players, coaches, and families who made this season so memorable. We are incredibly proud to support our local athletes and continue our partnership with three fantastic area programs; Portsmouth Little League-Portsmouth, NH, Somersworth Little League & Greenland Recreation Department T-Ball. We hope everyone had an absolute blast out on the diamond, made some great memories, and learned a lot along the way.

Small footprint, big impact. For this , we’re looking back at our Eco Homes at Lakeside project in Dover, NH (completed in 2022).

Infill development can be a puzzle, but it’s one of the most sensible answers to the housing shortage. By building 3 high density homes where infrastructure already existed, we minimized environmental impact and maximized efficiency. Doing more with less land, that’s a sensible way to provide housing.

Elevating every sqaure foot!

The best homes are the ones that grow with you. By transforming an unfinished basement into a premium living space, you aren’t just adding value to your property, you’re creating a backdrop for future memories.

This recent basement completion in Newfields, NH reflects our client’s style and needs, featuring a custom fireplace, a wet bar, and a full bathroom with a walk-in tile shower.

Ready to transform your unused space? Contact River Birch Builders today to learn more about how we can help you design and build a basement that fits your lifestyle.

Phase 2 of our Greenland, NH renovation is officially complete! A multi room master suite was transformed into a refined, functional sanctuary tailored perfectly to the homeowners. From re imagining the layout with custom cabinetry, the addition of lighting and trim details, and to the final finishing touches, this project was all about creating a seamless, elevated space. We’re proud to continue our work on this beautiful home.
