But Ken Draeger's project kept growing and growing, until he had built a Lego replica of Civic Square.

The finished product included a quarter of a million bricks, $30,000 of Mr Draeger's money and about 800 hours of work.

``The post office was the most challenging . . . There's more detail, more intricate design, more features to it,'' he said.

``My favourite was the Public Building opposite the post office.

``I used Google Maps and Google Earth, and 1000 photographs from all different angles.''

Mr Draeger was co-organiser of this weekend's Brixhibition, a Lego exhibition organised by TAZ-Brick and Kings Meadows Lions Club.

The exhibition features entries from TAZ-Brick's school competition, huge Battlestar Galactica models and Lego Technic.

More than 3200 people attended yesterday.

Mr Draeger said many had stopped to congratulate him on his display.

``I've had the Launceston Show Society ask to display it at the show,'' he said.

``If it doesn't live somewhere it will have to be broken.''

Brixhibition continues today at Kings Meadows High School from 9.30am to 4.30pm. Entry is a gold coin donation. 

The winner of the schools' competition will be announced at 3pm.
