Treowen offers capacious accommodation for very large parties - twelve bedrooms (5 double, 2 twin, 4 either twin or double and 1 family room with a double and a single bed) and reception rooms to match. All the beds are supplied with bedding, there are in addition ten camp beds and two cots without bedding available.
The dining room has an open fireplace and two refectory tables seating thirty in comfort. Up to forty can be seated in the dining room or if you feel more expansive the banqueting hall will seat eighty five to ninety.
There are two sitting rooms on the ground floor, the former nursery and the Oak room - an oak panelled gem with open fireplace. The long drawing room on the first floor is a room for concerts and celebrations - huge open fireplace and grand piano.
The banqueting hall now has its original passage screen and the huge open fireplace has been restored - table tennis and pool table.
The kitchen with its farmhouse table has cutlery and crockery for thirty six (with more if required) with cooking utensils to match.
Five of the bedrooms have en suite showers and W.C.s. There are a further three shower rooms and one bathroom all with W.C.s and three separate W.C.s.
The south garden with informal beds has sweeping views over a ha-ha of historic fish ponds and across a valley landscape. To the east of the house the ha-ha was extended to form a belvedere and the revetment round the raised walk surrounding the main Tudor garden to the north of the house was restored between 1997 and 2005. The area within the tall yew hedges on the raised walk is being remodelled as a parterre.
