Excited to be working with our friends at Dellbrook on 355 Bennington Street in East Boston, MA. Our crews are busy installing flooring and tile throughout the 6-story, 170-unit structure.

With a 213,272 SF footprint, the final building will feature multiple top-tier amenities, 7,000 SF of retail space, outdoor gathering spaces, and underground parking. And we can't wait to see the final result!

We are flooring it!

Check out these gorgeous spaces at the recently opened Overlook Apartments in Somersworth, NH. We had an incredible time partnering with our friends at Procon Inc. to provide the flooring for this massive 133,331 SF, 5-story residential community.

Featuring 135 stylish apartments, top-tier modern amenities, and prime access to the Portsmouth Naval Shipyard, this place is truly something special.

Congratulations to our friends at Harvey Construction on the official opening of the Mark Stebbins Community Center in Manchester, NH! Our company is proud of the beautiful flooring we were able to provide for this project.

The 20,000 SF community center is anchored by the Boys & Girls Club of Greater Manchester and Amoskeag Health, and unites multiple non-profit organizations to deliver comprehensive, wraparound services to children on Manchester’s West Side.

Many thanks to Harvey Construction for making National Granite Flooring a part of this meaningful and impactful addition to the City. We wish the Mark Stebbins Community Center tremendous success!!

This 5-story waterfront construction project added a beautiful, and much needed housing community to the City of Haverhill.

It earned our friends at Dellbrook a Project of the Year Nomination. And we are so proud of the work our team did flooring every inch of it.
