Environmental testing firm Gulf Coast Analytical Laboratories has bought its GSRI Avenue office for $1.65 million.

Allison Naquin, the company’s technical director, said there are no major changes in store for the company, just that it had decided that owning the building it has always leased was the right move financially.

The transaction also included property at 2103 Sampson St. in Westlake in Calcasieu Parish for $125,000.
