Members of the public are being invited to take a tour of a partly-built £10 million community facility in Corsham.
The Midas Group is opening the doors of its Springfield Community Campus project on September 27 and 28.
It will give people the opportunity to see behind the scenes, ahead of the sites opening in October 2014.
The finished campus will include a sports centre, community centre, library, council offices, play area and a police station, and will connect to the existing leisure centre.
Midas chief executive Alan Hope said: "We are delighted to take part in the Open Doors initiative and provide an opportunity for people from the local community to see behind the scenes at a live project going on in their area."
The Open Doors scheme is a national initiative aiming to showcase the career opportunities on offer in the construction industry, and better promote the varied skills involved in creating new buildings.
You can book a place on a timed tour by visiting www.opendoorsweekend.co.uk, but early booking is essential as places are quickly snapped up.
Tours run from 9.30am until 4pm on Friday, September 27 and from 9.30am until 12noon on Saturday, September 28.
