Patio Advice Please, drainage gully alongside house?

you should never build any type of patio or path close to house unless its at least 2 course below damp ..if your ground level is high ..then you must start 300mm (a foot )away from house ..BUT you must remove the soil in between the patio and house to a depth of 3 bricks ..then put in pea gravel to leave 2 course clear ...if you don't do this you will have problems possibly with damp but definitely with surveyor when you come to sell
