You will find this pole and any other modular fishing type are easy to work with at height once you understand how they work. 4 floors at say 10ft is within easy reach. That should reach your building, then you just add/buy sections to go higher. But it aint as solid as a glassfibre/alu pole
However, you dont get something for nothing. They are on the limit of the lightest you can go for a given height/price, I believe this British pole is currently leading the world with respect of lightness.
I phoned them today and the web designer let them down, they hope he will manage to get it on line Friday.
