The Hospital provided accommodation for 65 patients. On the ground floor were situated three large, well-lighted wards, and a 20 bed wooden annexe, built by the Military when they moved in. The annex was on the east side of the house, accesible via what is now the fire exit in the indoor cafe.

On the ground floor was an excellent Operating Theatre replete with up-to-date fittings, including folding operating table, high pressure steam sterilizer for dressings, and wash-basins with elbow swing taps (We believe this operating theatre is now the kitchen in the museum.); a Pack Store for the bestowal of the patients’ belongings and kits; kitchens, pantries, and other offices, and a large Recreation Room (probably the Billiards room in the museum). 

On the first floor were three smaller wards, commanding pleasant outlooks over the park; an isolation ward for two beds; bathrooms for staff and patients; rooms for the matron and nurses; and offices for the Commandants and Secretary. A few rooms were available on the top floor, but were not used on account of their inaccessibility.

Wounded soldiers were sent to Wardown from the 1st Eastern General Hospital, Cambridge, to which it was affiliated, and sick were admitted from the nearby Biscot Camp Artillery Training School and other units in the town.

Cases requiring major operations were sent to either the Bute Hospital in Luton centre, near the present day post office, or the 1st Eastern General Hospital, Cambridge, according to their nature and urgency. X Ray examinations were made at the Bute Hospital.

The Recreation Room on the ground floor was furnished with comfortable chairs, writing and card tables, indoor games, a small library, and an excellent bagatelle table. A second bagatelle table was placed on the first floor landing. In the Entrance Hall and in each ward hung a table of rules and regulations, to which patients were expected to conform during their stay in hospital.
