DEERFIELD — More than a decade after first receiving approval, Walter’s Propane will finally construct a small office building at 225 Greenfield Road (Routes 5 and 10).

With site plan approval from the Planning Board on Monday, Walter’s Propane, run by Richard Strycharz Jr., will construct a 32-foot-by-56-foot office building.

Walter’s Propane was originally permitted to build a 60-foot-by-60-foot building in 2013, but never completed it. Instead, the company will construct this smaller building to stay out of the 50-foot wetlands setback, according to JD Ross of Whately-based JDR Builders.

“[Strycharz] did everything on that land but build the building,” Ross said to the Planning Board. “All the stormwater management, all the grading, parking, everything has been done, except putting the building up. Now, his business has grown to the point to where he needs to get this office out of his house.”

Ross noted Strycharz has “done an exceptional job maintaining the property” in the time since the initial approval in 2013.

With every other aspect of the project already completed over the course of a decade, Ross said there will be little change to the neighborhood, especially since the building will see little traffic because the only thing customers can do there is drop off payments.

“There’s no services open to the public in this building, other than coming to drop off a check. They can’t come in and buy propane, they can’t get a tank filled,” Ross said. “There’s nothing for sale at this building.”

The office will also have an attached two-bay garage to store personal vehicles and general equipment. No propane trucks will be kept there.

While public comment and questions from the Planning Board were limited on Monday, abutter Valerie Niemann had a mild concern over some lighting at the property. She noted Walter’s Propane has “been a fine neighbor” over the years, though.

Ross said they expect to add a light above the building’s entrance, but lighting conditions should remain the same otherwise.

The Planning Board unanimously approved the site plan for Strycharz’s office. The Conservation Commission approved the project in late July.
