It's a noble idea, I don't know any high-end estate with piped gas, it's not more economical than cylinder gas, we tried doing it on a high-rise we are working for, but after the London tower fire the client decided against it, first let's check the wayleaves we have even in high-end estates, not very clear we dig up roads without notice to even kenya power how will we handle gas, I think that before we lay gas pipes we need to check our footpaths, roads, sewer, power lines storm water drains, internet lines then gas last.
