Well thought out design, allowing for placement of doors and windows as you require also the ability to set the pent roof slope in either direction. Excellent quality materials NO OSB or chipboard. My only ‘would be better if; floor was in one piece, it would be stronger. Although, by placing floor on a strong level set of bearers there is no problem. Quick and free delivery. Highly recommended. Build time for 6 x 4 with 2 people 4 hours. Good delivery but 2 corner fillers damaged. Replaced with no issues plus a second free shelf kit as an apology. Many thanks
