It will take some patience and time to put this together. But is is a good time, especially if you don't try to rush it. My 12-year-old son and I are having a blast putting this together. Neither of us are full fledged Lego hobbyists, but both of us enjoy the concepts and quality of good Lego kits.
The building assembles in three major sections, each corresponding to one floor of the three-story structure. The parts bags are labelled with their section numbers, do you don't have to mix the parts together for all three sections while you are building it, saving a lot of part-searching time (but never fear, the high number of pieces in each section means you will still spend plenty of quality time hunting for elements).
This kit makes fantastic use of basic Legos and has virtually no large pieces that are overspecialized, making the kit far more flexible to rebuild into other types of assemblies. For instance, the large white fan-shaped sunburst decoration over the main door is composed of a number of small Lego "ski" pieces using a creative way to link them together. The creative construction techniques in this kit encourage you to think of new ways of using Lego bricks that will help you design your own creations if you are so inclined.
This kit was definitely worth the price we paid at Amazon, although you should be aware that some third party Amazon sellers try to charge far more that list price for it. To look up the list price for this (or any other) Lego set, I recommend you seek out dedicated Lego sites like Lugnet or Brickset.
One note: this kit is inapproriate for very young Lego builders based on the sheer size and the number of different building techniques they would have to use to assemble this kit correctly, unless an adult could sit with them and work through it with them. My 12-year-old could easily do it by himself, but my 7-year-old would lack the patience.
