 Balfour held the surveyor 's post until 1910 , when he was succeeded by Edmund <unk> . His second decade in the role was less significant than the first , because the death in 1899 of the 1st Duke brought the estate a bill for £ 600 @,@ 000 in death duties ( equivalent to £ 60 @.@ 9 million in 2016 ) . The resulting financial pressure meant that little rebuilding occurred until 1906 , and when it resumed Balfour 's influence was diminished . He had little affinity with the hedonistic young Hugh Grosvenor , 2nd Duke ( grandson of the 1st ) , who Edwin Lutyens and others had persuaded to adopt a less rigid architectural policy .
