I ordered a BillyOh Kent Garden office building. The sales team informed me that 2 people could build this in a weekend (this is a lie – see below). A team of 3 of us spent 3x 10hour days (total 90 person hours) paining the individual parts of the building with wood protection (before the building was assembled). During this process we discovered many of the parts were severely warped and twisted or cracked. The quality of the wood is very poor (rough-cut pallet wood is used for the window and door frames). After several emails to GardenBuildingsDirect (Also known as Kybotech Limited) they agreed to send replacement parts. These replacement parts arrived, but several of these parts were also severely warped. We spend the whole of the next weekend counting the parts (300+ different large and heavy wooden parts) and found that lots more parts are missing! GardenBuildingsDirect (Kybotech Limited) were not willing to accept their poor quality control and send the replacement parts without us proving that they are missing or damaged! We have wasted 2 weeks now waiting for replacement parts to be provided and met with resistance from GardenBuildingsDirect (Kybotech Limited) when asking for replacement parts. Regarding the construction time - the building comes with over 2,500 screws and nails. This would mean that to complete in 1 weekend, working continuously 8 hours per day without a break, you would need to insert a nail or screw every 23 seconds without stopping!! Therefore there is no chance this can be assembled in 1 weekend on top of all the other work required in lifting and hanging doors and windows and all roofing felt etc...(And not including the 90 hours required for the first coat of wood protection). Therefore I feel that I have been lied to when told that this can be done in 1 weekend and the customer service in sending replacement parts is shockingly bad.
