R&G Ventures, an incorporation of Summers-Taylor owners Rab and Grant Summers, officially closed on the former Model Mill property on Dec. 15, and heavy equipment has been in motion this week taking down an old loading dock while other demolition is underway. About one-third of the property will be turned into the construction company’s headquarters. The remainder of the property likely will be leased as office and retail space. Grant Summers said equipment and materials are being removed, and another contractor will begin cleaning up the area of the building destroyed by fire on Sept. 25 in about one week. He hopes the transformation can be completed near the end of 2018.
