Builds

Cold Storage Construction
at Any Scale.

We build walk-in coolers, freezers, cold rooms and refrigerated buildings. We also build controlled environments — rooms designed to hold more than temperature.

Start Your Project

One system, every size.

Same Panels. Same Standard.

Walk-In Coolers & Freezers

A box in your kitchen or outside on a pad, built to take the weather. Built to fit your space — never a prefab, standardized kit.

Cooler, freezer or combination, indoor or outdoor
Single rooms take 2 to 4 days on site; bigger boxes take 5 to 10 days.

Cold Storage Rooms & Buildings

A cold room inside your building, or a whole building built entirely cold.

Box-in-a-box cold rooms, multiple temperature zones, and insulated floors
We value-engineer the design, handle submittals, and draft detailed shop drawings, all on the GC’s schedule

The Standard

The Standard That Doesn’t Change.

Three things that stay the same, no matter the size.

Built to suit.

Prefab boxes are built for average spaces. Yours isn’t. We cut panels to your layout, doors to your openings.

Right the first time.

Built to Perform. Built to Last. At RSNE, our highly experienced team treats every panel and door job as if it were their own. That’s the ultimate standard.

Accountable, start to finish.

An experienced RSNE Crew Leader runs every job, from initial layout to the final piece of trim. Your single point of contact that we hold accountable.

FAQ

Questions before you build.

What’s wrong with a prefab walk-in kit?
Nothing, if your space is average. Prefab boxes come in standard sizes; your kitchen doesn’t. More in prefab versus custom walk-ins.
Can a walk-in cooler go outside?
Yes. A walk-in cooler can sit on a pad outside — roof, rated doors, walls and floor built for New England winters. Often the fastest way to add storage.
Can we expand it later?
Usually. Panels go up in sections — walls move, boxes grow. Tell us where you might be in five years.
Where does RSNE build?
All six New England states and New York, day to day. Major projects go nationwide. We're headquartered in Lakeville, MA.
