Concrete Office / Shed Eample 1

Here im looking at concrete construction, because im basing my major project on that form of structure. From this design i was looking at cleen joins between the precast pannels and the way they plan to cover the precast concrete pannels with aluminium pannels. I also took notice of window and door joinary, where they meet the concrete. Also noticed the floor level is flush with the ground level. Box gutters also took my eye how the down pipes penetrates the concrete so smoothly and untoticably.
