The American Institute of Architects has announced the winners of this year's Small Projects Awards, which include a tiny floating sauna and a mobile dental surgery in a trailer (+ slideshow).
The AIA chose nine small-scale projects by US architects for the 13th edition of the annual awards, which recognises the best from the past year.
Recipients are divided into two groups: category one encompasses small builds, objects, works of environmental art or architectural designs up to $150,000 (£113,000) in construction cost; category two is for small projects up to $1,500,000 (£1,130,000) in construction cost.

Selected by a jury of industry professionals, the winners also include a cabin clad with blackened pine in a Wisconsin forest.

"As architects we strive to provide clients with more than just buildings, but solutions to improve life ? these projects highlight this notion."
