LEGO 10234 Sydney Opera House is the most recent entry into LEGO’s lineup of large creator expert landmark models (at least until the rumored Big Ben arrives later this year), but it could also be the next one to retire. There certainly are signs to suggest this, and if it indeed retires this year, collectors and investors could be very happy with the potential appreciation in value on such a large set. LEGO’s Sydney Opera House set is a gigantic model by any metric. It consists of 2989 pieces, and measures over 60cm / 2 feet in length. Like the other models in the creator expert landmark series, it does not include any minifigures. Some people wonder about the quality of the build, since there are many repetitive elements to it, such as the roof and the stairs, but this is really a non-issue. All similar models feature significant repetition, such as 10214 Tower Bridge, and 10181 Eiffel Tower but those sets are still very desirable. In fact, 10189 Taj Mahal is one of the most valuable LEGO sets in existence and it is an extremely repetitive build, but that’s just the nature of faithfully modelling these structures. The most important thing to buyers is that the model be large and accurate.
