Top architecture practice Aedas is one of five taking part in the challenge
Five of Scotland's top architecture practices have accepted a challenge to design a building out of Lego.
Prospect magazine said the project was designed to show "how even the humble plastic brick can be turned into a work of architecture in the right hands".
The Lego buildings will be displayed at the Scottish Design Awards Nominations Exhibition on Wednesday.
The designs, which will also be shown at the Lighthouse in Glasgow, will be auctioned off for charity in May.
The winner of the Lego challenge will be announced at the Scottish Design Awards Gala Dinner on 29 May.
The money raised from the auction of the buildings will go to the National Autism Society Scotland.

The five practices involved were: Aedas, Gareth Hoskins Architects, gm+ad, Michael Gilmour Associates and RMJM.
Gordon Young, editor of Prospect, said: "We were amazed at the ambition and scale of some of the entrants.
"We had tower blocks, big blocks and plain odd blocks.
"It's amazing to think all the teams started out of standard Lego building bricks. Imagine what could have been achieved if they were working with real bricks."
Despite the credit crunch the real Scottish Design Awards, which cover disciplines which range from building design to graphic design, have seen record entry levels this year.
Buildings in the running for the top awards include: the Beatson Cancer Research Building in Glasgow, Quartermile in Edinburgh and Moore Street Housing in Glasgow's Gallowgate.
