The LEGO Group and Brickstructures Inc. have unveiled a great product labelled LEGO Architecture. The LEGO Group and Adam Reed Tucker of Brickstructures officially introduced the LEGO Architecture line in 2008, which now contains six different models and from the images I've seen so far, I am quite impressed. It is difficult to determine the exact scale of the models from the boxes, but most of them look simple enough that I imagine the scale to approach 1/500 to 1/700. It is also possible by comparing the different models to note that Lego has not selected a specific scale for the line, but rather has let the model itself decide the scale. It really is whatever looks good, and I think they look very good. Here is the image that can be found on the Lego website, in the Architecture Series section:
I look forward to getting my hands on one or more of these kits (specifically the Frank Lloyd Wright models). If you haven't played with Lego in a while, give it a try. It is a fantastic way to develop and improve your imagination!
