Pretty standard stuff for someone like Jewson and Buildbase to supply you with. Common sizes probably in stock - others to special order within a few days.
Requires Building Regs approval if within your house.
Do you really mean 3000 cms?That is thirty metres!!
Some lorry to bring it to you and an army of men to lift it or a job for a crane!!! Delivery alone would be a large sum.
