SVP's Terrace roof

[techie lady]

Hi I am currently looking at soil vent pipe routes to a house, however the situaation is i the bathroom is situated under a roof terrace and the last thing i want is a big SVP sticking out of the middle of my roof terrace so is there a way i can vent it out horizonatlly through the wall instead of up through the roof???
An air admittance valve is not an option

are you sure you dont sound very ceryain!!! only joking, not what i wanted to here....
so my only option is to not have the toilet under the terrace then?
