Simkins, who owns multiple buildings in the downtown, formerly operated Newbury Perennial Gardens.
Urban Elements, which has operated a store on Pleasant Street since 2007, recently expanded to a storefront on Merrimac Street that for many years was the main entrance to the Fitness Factory.
Cebula Design, Inc. at 18 Liberty St., an interior design firm, is expanding by adding a showroom at that location, said Michael Cebula, design director.
The company offers high-end furniture, accessories and design services, mostly to homeowners on the northern coast of New England.
The repositioning at 18 Liberty has meant that several businesses have moved to new locations.
Chameleon, once at that location, has moved its fine arts inventory to 22 Liberty St., the address where it started in 1994.
And Rocas, which had been at 22 Liberty, has relocated to 1 Merrimac Landing, Unit 8.
“I like the greater amount of foot traffic here,” said Rosemary Silva, proprietor of Rocas.
Also at 1 Merrimac Landing, Suite 4, is a new venue called Pure and Simple HOME, opened by A.J. Aubrey. It offers “all home decor” and interior decorating services and will open by Friday, she said.
