GVA Grimley and Cushman & Wakefield have completed the sale and letting of all units at Bankhead Estates's Bankhead Workspace development at Sighthill Industrial Estate, West Edinburgh, less than a year after planning permission was granted.

Each one of the eleven modern, self-contained units, which were all under offer prior to completion, was sold off-plan for more than £100 per sq ft.

This latest deal sees Napier University take a ten-and-a-half year lease on the 6,137 sq ft (570m2) unit four, the largest of the units, at a rental of £7.50 per sq ft.

Commenting, Toby Withall, office agency partner at GVA Grimley, said: "Bankhead Estates's foresight in securing this site has certainly been rewarded."

"There was significant interest in each of the units from the outset, which is reflected in the speed with which we've managed to secure purchasers, the price the units have been sold at and the fact we were able to sell them off-plan.

"Napier University has done well to secure the lease of the final unit in the face of some serious competition."

Chris Cuthbert, office agency partner at Cushman & Wakefield, added "Having seen the site totally transformed in such a short space of time has been fascinating to witness. It was one of those properties that could have easily been overlooked, and demolished, to be replaced with something new. Instead, the developers idea of converting what was already there has paid off for everyone!"

Bankhead Workspace sits on the site of the former Johnson & Johnson / Ethicon factory, which was acquired by Bankhead Estates - a joint venture between directors of New land Assets Limited and Plum Developments Limited - in June last year.

Planning permission was granted in October, allowing the original 24,196 sq ft (2,248m2) structure to be converted into the separate units which have proved attractive to business owners looking to purchase premises in Edinburgh.

Commenting for Bankhead Estates, the company's director, Angus Hamilton, said: "The conversion of the larger building into individual units presented smaller businesses with a rare chance to purchase within Edinburgh, so we expected demand to be high. However, the speed with which they have been snapped up is fantastic and is testament to the marketing teamwork carried out by GVA Grimley and Cushman & Wakefield."

Angus noted that Bankhead Estates is already working on the next scheme to meet the demand from owner occupiers. "At City Park Industrial Estate in central Glasgow we are offering units from 5,000 to 40,000 sq ft for sale or to let. The early signs are extremely encouraging with 4 out of the 10 units either occupied or under offer".

Earlier in the year, GVA Grimley and Cushman & Wakefield sold Birch House, another Bankhead Estates property adjoining Bankhead Workspace, to Cosmopolitan Investments Limited for £820,000.
