Ten years after its previous section was completed, a Henrico County office park is entering its final phase of development.

Site work to expand the Gaskins Professional Office Park is underway at the intersection of Three Chopt and Gaskins roads. Plans call for four buildings totaling 30,100 square feet.

The work picks up where developer Katherman & Co. left off in 2008, when the Midlothian-based firm started development on the park as its first foray north of the James River.

Ten years later, the company began to explore the park’s next phase of development after some initial buyers began reselling their units, said Tucker Dowdy of Commonwealth Commercial, who is marketing the new offices for sale with fellow Commonwealth broker Russell Wyatt.
