THE LEGO Group is set to pay homage to one of the greatest buildings of the 20th century when it debuts a new Sydney Opera House model on September 1.

The construction skills of LEGO® fans from around the world will be put to the test as they recreate the Opera House using advanced building techniques and almost 3,000 LEGO bricks.

The Opera House model will be an authentic representation, scaling 28cm high x 63.5cm wide x 38cm deep.

It will stay true to the harbour surrounds with the introduction of the LEGO Group's largest blue stud baseplate ever and dark tan LEGO bricks, including the rare 1x1x2/3 stud and 1x2x2/3 stud slopes.

The model will retail for $399.99 and joins the LEGO Creator Expert product range, which has seen the Taj Mahal, Eiffel Tower and Tower Bridge immortalised in LEGO bricks.
