Is he Portsmouth or Gosport based? You could ask for Alverstoke in Gosport - lovely village like atmosphere and if he is the sort to cycle to work he can cycle to the ferry to go over to Portsmouth If not the old quarters in Hillhead are nice, big as well - new ones are very pokey there but it's a lovely place - he would have to drive to Portsmouth daily Not sure about the ones Pompey side you need to ask Talcandturnips
There are newish build (about 6 years old) houses at Daedalus in lee on Solent. They are modern and large and there are plenty empty at the mo. the drive around to Portsmouth can be slow in rush hour though. Hope that helps!
