Buckinghamshire is host to a large section of the Chiltern Hills and much of it is classed as Green Belt. It hosts Chequers, the country house of the UK Prime Minister, built in the 16th century and located near Ellesborough, and Bletchley Park, where the Enigma Code was cracked during the 2nd World War.

The most densely-populated urban area is Milton Keynes but the towns of High Wycombe, Amersham, Chesham and the Chalfonts host much of the county's population: these towns are all part of the London commuter belt.

Properties in Milton Keynes are all post-war and largely consist of standard construction detached, semi-detached and terraced houses along with purpose-built flats. Milton Keynes itself has seen some redevelopment in the last 20 or so years. 

Older period properties can be found in the older towns, villages and hamlets such as Marlow. Beaconsfield is a highly affluent town and has some very large detached homes, some of which are period properties but many are 'knock downs', where the original property was knocked down and a new one built in its place.

There are many newer developments, particularly in the more densely populated areas.

There is considerable affluence in many parts of the county, such as around Fulmer, Gerrards Cross, Farnham Common and Stoke Poges. Denham Golf Club, which has its own station on the Chiltern Line, is the haunt of many celebrities who have dwellings in the area. The county is the site of the first modern private university to receive a charter, the University of Buckingham. Buckinghamshire has number of areas of outstanding natural beauty, such as Burnham Beeches and the Chilterns (including the Chess Valley).
