William Kent [SEP] Architectural works
These neo-antique buildings were inspired as much by the architecture of Raphael and Giulio Romano as by Palladio. In country house building, major commissions for Kent were designing the interiors of Houghton Hall (c.1725–35), recently built by Colen Campbell for Sir Robert Walpole, but at Holkham Hall the most complete embodiment of Palladian ideals is still to be found; there Kent collaborated with Thomas Coke, the other "architect earl", and had for an assistant Matthew Brettingham, whose own architecture would carry Palladian ideals into the next generation. Walpole's son Horace described Kent as below mediocrity as a painter, a restorer of science as an architect and the father of modern gardening and inventor of an art.
