Wiltshire Council says its scheme to build a new leisure centre opposite County Hall in Trowbridge "has really come to life" in recent months.
The major project will deliver "modern, accessible facilities" in Wiltshire's county town and work began in April, with Pellikaan Construction leading the build.
The council has released timelapse footage of the construction site which shows how the new structure has grown and changed over the last eight months.
A spokesperson said: "This year the new leisure centre in Trowbridge has really come to life, with work on the roof getting underway earlier this month.
"Take a look at how the site has transformed. We're excited for what's to come in 2026."
Cllr Mel Jacob, cabinet member for communities, engagement, and corporate services, believes the centre will transform the area.
She said: "This centre, once complete, will be a transformative asset for the town and surrounding communities, providing modern, accessible facilities that promote health, wellbeing, and connection.
"We're very excited to see progress on-site and will keep people updated as this project continues."
