Birmingham Town Hall has scooped the title of Project of the Year in the West Midlands regional heat of the RICS Awards.

And the building was also named winner in the Building Conservation category where entrants must show they have paid particular attention to background research, the construction materials and techniques used, and the project's long-term prospects.

The refurbished and extended Fort Dunlop building was announced as winner in the Sustainability category – an award which measures a project's commitment to the efficient use of resources and celebrates schemes that provide sustainable environments.

Gurdip Chamba, RICS West Midlands regional chairman, said: "The RICS Awards celebrate excellence in managing the wide variety of buildings that make up our rich built environmental heritage. The standard of competition for our awards, as always, has been extremely high and these iconic city-centre buildings are truly deserved winners."

Now in their 18th year, the RICS Awards celebrate and recognise exemplary projects across four award categories – building conservation; regeneration; sustainability and community benefit.

Birmingham Town Hall, a Grade I listed landmark, has undergone a £35 million restoration, and the building has been lovingly and painstakingly renovated by a dedicated team of conservation and construction professionals.

Urban Splash, with architects shedkm, converted Fort Dunlop into 234,000sqft of offices, retail and leisure space and a 100-bed hotel – transforming the former tyre factory, after standing empty for 25 years, into an iconic building and 24-hour destination for business and enterprise.

The RICS Awards West Midlands final was hosted at the Botanical Gardens on Thursday by broadcaster Nick Owen, and formed part of the organisation's annual regional dinner.
