The Library of Birmingham has been crowned project of the year for the second time in the space of a month.
In April, the Royal Institute of British Architects awarded the £188 million library three of three four prizes on offer at its 2014 West Midlands Awards including the overall building of the year title.
This has now been followed by recognition from the Royal Institution of Chartered Surveyors, which named it project of the year at its 2014 West Midlands Awards.
A 16-strong panel of judges said the library triumphed over what it described as an "exceptionally strong field of entries".
Judges praised the collaboration between Birmingham City Council and contractor Carillon, its leading edge design, sustainable features and community engagement.
Chairman of the panel John Sharpe said: "The Library of Birmingham is a more than deserving winner of the RICS West Midlands Awards Project of the Year 2014.
"It absolutely embodies the values judges look for in a development. It serves its users in a way few other projects could and, since opening, has proven itself at the heart of the community.
"All the judges were unanimous in selecting the library because it is an iconic landmark building which makes a bold statement about Birmingham's confidence in itself as a world city."
The winners of the eight individual categories were:
- Building Conservation: Bank Farm & Threshing Barn, Carden
- Commercial Property: Two Snowhill, Birmingham
- Community Benefit: Cobridge Community Health Centre, Stoke-on-Trent
- Design and Innovation: The Library of Birmingham, Birmingham
- Infrastructure: A45 Transport corridor Improvement Scheme, Birmingham
- Regeneration: Jaguar Land Rover, Wolverhampton
- Residential Property: Red brick: green house, Stoke-on-Trent
- Tourism and Leisure: Oswestry Leisure Centre, Shropshire
Winners in four of the categories - building conservation, community benefit, design and innovation, and regeneration - will be entered into the national awards which takes place later this year.
A total of 43 projects were shortlisted for the ceremony which was held at The Heart of England Conference and Events Centre, in Warwickshire, and hosted by architect George Clarke who presents Channel 4 show Restoration Man.
