Advice with toilet that is largish distance from stack

I'm having some dormer work done and moving my bathroom - the problem is that the distance of the new WC location is approx 7 metres (this distance also needs a 90 degree bend adding into the equation) from the soil stack - building regs seem to state a maximum of 6 meters from the soil stack to the WC that I can understand.

I don't want to use a macerator, so what other options are open to me ? - I've been told a durgo or maybe a sub stack would be the solution - I'm a sparky so not sure how these would fit into the system.

Any advice would be much appreciated
