Instructions, building fun, robust and super beautiful final result
got this for my 10 year old grandson for Christmas and he loved it. Its pretty small but he really enjoyed doing it. I also bought the lights to go with it and whow! best present ever..
Guaranteed hours of fun.
As described, I was able to purchase a good product at a reasonable price. It's a trustworthy seller!
I think the product is pretty expensive for what it actually is, however LEGO Architecture is expensive and is the slightly more 'adult' LEGO product on the market, however I'm a firm believer of loving LEGO at any age!! Amazing centre piece to put on display. It was sooooooo fun to build! Satisfying, therapeutic and educational! Love the facts and statistics spread throughout the instructions, teaching you about the building.
What I particularly like: endless fun, good quality.
Nice large set, fun to build and good value for money.
Very nice and aesthetically pleasing. My 8-year-old son really likes the LEGO Architecture collection, which are both beautiful and interesting, especially this one. It's a shame they aren't affordable for everyone.
Really fun playtime! There were 2 missing pieces, but they could easily be ordered via the LEGO website.
A substantial and beautiful design. Unfortunately, the back doesn't offer much. Building it still provides a few enjoyable hours. The box was delivered very quickly! It is definitely recommended.
Hello, once again, LEGO has given us two new models from the Architecture series that fans can look forward to: - The Capitol, 1035 pieces - Buckingham Palace, 780 pieces. I saw the new models (Architecture Capitol + Architecture Buckingham Palace) in a shop in Bozen during my vacation in Italy and was surprised that they were already available for purchase there. I waited for several days and finally bought the products at a lower price on Amazon. I would also recommend this to everyone, as they are always a bit more expensive in the shop. The model itself is of course very beautiful. It looks great in my Architecture display, and depending on how you want to have it, you can also place it on your desk, where it also makes a great impression. Especially because the model is very wide (about 40cm) and with 1035 pieces, it is one of the larger models from the LEGO Architecture series and is very faithful to the original building in the USA. It is clear that the model is not intended for playing and is more for adults. However, children and teenagers can also enjoy the model, which brings me a lot of joy. The assembly is typical of LEGO, intuitive and very easy. The instructions are very clear and in the typical LEGO style. A 5-year-old can easily build it ;) The model is therefore intended for display, playing with figures and so on is not possible. At a price of 85€ (at the time of my review), it is of course not nothing, but perfectly acceptable for the model. I would have actually not wanted to pay more, here on Amazon you have a small price advantage (The model costs 99€ in the shop). Conclusion: Overall, a great model, the assembly is fun and the model looks good. You can also (see photos on Amazon) remove the dome, which allows you to take a look inside. I am satisfied with it. Worth a recommendation! Greetings, Dennis
