No. 42 Pall Mall, in Central London 

‘Great Tew had improved Mr. Loudon's health and earned him more than his father had ever done. So by 1811, he was ready for an adventure. He sold the sub-leases on his farm and moved to No. 42 Pall Mall, in Central London.’ This is a quote from The Claudians: gardens, landscapes, reason and faith: John Claudius Loudon and Claudius Buchanan, Tom Turner (Kindle, 2024).
