I've made an offer on a house that has brown pebble dash on all the exterior. I don't like pebble dash or brown. 
Inside of house, garden, driveway etc. are all lovely so I'm willing to compromise on this, hopefully can change it at leisure.
I'm not particularly savvy with building works, so is there an option to get it rendered more smooth or could I just get it painted one, lighter, colour? What sort of budget would I need. It's a 3 bed semi, north Liverpool.
thanks!
