Delivered as promised on time, build was done single handedly, only required help with felting.
I was a bit apprehensive about 19mm boards, but pleasantly surprised they were better than i imagined.
Flooring is pretty thin, but I had already planned OSB board going underneath.
All in all delighted with purchase and will be great addition to our garden.

Delivered on time and delivery driver could not have been more helpful and is a credit to the company. Assembly was relatively straightforward and took about 20 hours over 4 days with my son and me who have minimal building skills and having the correct tools is vital. Some of instructions took a wee bit of reading to fully understand them, appears booklet has been photocopied repeatedly and pictures could have been clearer which would have assisted at times. Mrs and I are pleased with finished cabin and would be happy to recommend to others, appears good value and solid building which we will enjoy for years to come. Cheers

Will I receive a timeslot for my delivery?

As we use a wide range of carriers for delivery, you may not receive a time slot for your order.
