A mixed-use office and medical park on RM 620 will begin construction on its last lots in November, according to Ron Evans, principal at Huffman Builders. Evans said the last of the lots will be available for tenants by May 2015.

The mixed-use space, called Vista 620, has been in development for three years.

The site currently includes tenants such as Westlake Dermatology and Wellmed. Davita Dialysis Center, Hamilton Vein and Five Star ER are set to open at Vista 620 in 2015.

Huffman Builders also completed the Heatherwilde Professional Park and Medical Center in Pflugerville and the White Stone Professional Park in Cedar Park.
