This was a cathedral I built this summer. It has nearly 20,000 bricks with more than 3,000 of them being transparent parts. I spent about 30 hours building time, but took 6 months to collect all the bricks. This is built entirely out of classic, light grey bricks.
Impressive architectural details! No studs visible on the facade; it looks very polished. The interior shots on your web site are cool. The pipe organ is quite good. I am amazed that you could build such a large and detailed structure in only 30 hours. A good close up of the large stained glass window would be nice.
