The £188 million Library of Birmingham was the big winner at the 2014 RIBA West Midlands Regional Awards where it took home three of the four prizes.
The landmark building, which was designed by Dutch architecture firm Mecanoo and opened last year, was named overall West Midlands building of the year by the Royal Institute of British Architects.
In addition, Patrick Arends from Mecanoo was named emerging architect of the year while the library's owner Birmingham City Council was crowned client of the year.
Making up the category winners was the Centre of Refurbishment Excellence (CoRE) in Stoke-on-Trent which won the sustainability category.
A total of eight buildings from across the West Midlands were named as regional winners by RIBA at the award ceremony - held at the Library of Birmingham - from which the four category winners were chosen.
Ashperton Primary Academy, Herefordshire, Warren Benbow Architects
Parkside, Birmingham City University, Associated Architects
Stoke-on-Trent City Centre Bus Station, Grimshaw
The Lighthouse, Birmingham, Associated Architects
Tudor Grange Academy, Worcester, Feilden Clegg Bradley Studios
Waverley School, Bordesley Green, Birmingham, Allford Hall Monaghan Morris.
RIBA West Midlands regional award winners will now be considered for a national award which will be announced in June.
The shortlist for the RIBA Stirling Prize for the best building of the year will be drawn from national award winners later in the year.
RIBA West Midlands chairman Gavin Orton said: "The range of buildings on show this year was very impressive. Perhaps the Library of Birmingham catches the eye but the diversity of projects, from the bus station in Stoke-on-Trent to the primary school in rural Herefordshire, all benefit from the talent, creativity and skill of architects.
"These awards demonstrate the value that an architect can bring to any project and I'm delighted that, yet again, we've had such a fascinating and interesting range of schemes in this region."
