Transform a fireplace wall with Weathered Plank by Dutch Quality Stone. It has the warm, worn look of reclaimed wood with the lasting character of stone, just in time for the colder months. Visit 9 Brothers Building Supply at any of our three locations.

Hexagons force a decision at every edge, which is exactly why a finished hex field looks so intentional. Hexa 60 from -bloc is HD², and the six-sided format lets a crew break a large slab field into something with rhythm instead of a flat sheet.

Send us the space and we will talk through the edge detailing.

Build a patio that stays level for years. It starts below the surface. Cambridge's installation guide calls for 7 1/2 inches of excavation for patios and walkways, 4 inches of compacted quarry process gravel, and a smooth bed of coarse sand before a single paver goes down. 9 Brothers Building Supply carries the base gravel and the Cambridge pavers. Visit any of our three Long Island locations.

The trick to a backyard that looks designed rather than assembled is repetition. Raffinato from -bloc runs as a wall, a coping cap and a fire feature in the same smooth polished family, so the eye reads one material everywhere it lands.

Ask us how a single collection can carry the wall, caps and features in your yard.

Salt air, blowing sand and freeze-thaw. East End patios take all three.

There is no single best hardscape material for a coastal Long Island property. Our new guide shows East End homeowners why the choice should start with an exposure brief, not a color board: salt spray, wind-driven sand, repeated wetting, freeze-thaw, drainage, snow removal and deicers. It covers how natural stone, concrete pavers and exterior porcelain each have to be matched to the exact exposure and installed as a complete system, why drainage and detailing can outweigh the finish, and why winter maintenance rules should be set before the first storm. Bring your plans to 9 Brothers Building Supply. Visit us in Brentwood, Riverhead or East Setauket.

A flat, tired yard and a yard with levels are two different places to live. A Prescott wall from -bloc is often the piece that does that: a chiseled-face wet cast wall that turns a slope into a terrace you can plant, sit on, and walk between.

Visit us to see Prescott wall in person 📍

Why do hexagons make such a strong design statement?

The geometry creates movement and visual interest before you add anything else to the space. Hexa 60 from -bloc pairs that distinctive shape with a dense HD² finish for a patio that feels intentional from every angle.

Would you use hexagons for the full patio or as an accent?
