Found the following article online, use it to answer the question: What was the specific Roger Pratt philosophy whose consequence resulted in the family occupying the rooms on the first and second floors of the west and east wings, with the state rooms in the centre?  The plan of the rooms at Belton was passé for a grand house of its time. Following the Restoration and the influx of European ideas, it had become popular for large houses to follow the continental fashion of a suite of state rooms consisting of a withdrawing room, dressing room, and bedroom proceeding from either side of a central saloon or hall. These rooms were permanently reserved for use by a high ranking guest, such as a visiting monarch. While Belton does have a saloon at its centre, enfilades of state rooms of lessening grandeur do not flank it. The possible reason for this unusual layout is that, while the Brownlows possessed great wealth, their title was only a baronetcy, and their fortune was barely a century old. They would have been regarded as gentry, not aristocracy. As a result, building a suite of state rooms would have been in hope rather than anticipation of a royal guest. However, the lack of a fashionable and formal suite of state apartments coupled with the Brownlows' lack of social credentials did not prevent a visit from King William III to the newly completed house in 1695. The King occupied the "Best bedchamber", a large room with an adjoining closet, directly above the saloon, that led directly from the second floor Great Dining Chamber.This design followed the older style of having reception rooms and bedrooms scattered over the two main floors. The layout used followed Roger Pratt's theory that guest and family rooms should be quite separate. As a consequence of this philosophy, the family occupied the rooms on the first and second floors of the west and east wings, with the state rooms in the centre. The great staircase, designed to be grand and imposing, rose to the east side of the house, and formed part of the guest's state route from the Hall and Saloon on the first floor to the principal dining room and bedroom on the second.The principal entrance hall, reception and family bedrooms were placed on the ground and first floors above a low semi-basement containing service...
