MYSTERY surrounds the demolition of an office block.

Dorcan House, which is a large purpose built office building divided into three interconnecting blocks, is being torn down by 777 group.

The site on Eldene Drive, next to Fit4less, was surrounded by hoardings and had a single digger working on the building yesterday.

It is unclear why the site is being cleared as no planning application to build anything else has been submitted.

Coun Kevin Parry, ward councillor for Dorcan, said: “We are keeping tabs on the site but I enquired about 10 days ago and there was no planning application for the site. I will be monitoring the situation to see what is happening.

“They are obviously entitled to pull it down if they wish it is a private building.”

Swindon-based commercial property agents Whitmarsh Lockhart are involved with the site but no one was available to comment on the developments.
