Historic England lists buildings in three grades: Grade I for buildings of exceptional interest (about 2.5% of all listed buildings), Grade II* for particularly important buildings of more than special interest (about 5.8%), and Grade II for buildings of special interest (about 91.7%). Listing protects the whole building, inside and out.
Every entry on the National Heritage List for England whose point lies inside the ONS 2022 built-up-area boundary. One list entry can cover a terrace or a group of buildings.
9 Grade II listed buildings
Most listed buildings are in this grade, which covers buildings of special interest. Open any building to read its official list entry.
2 conservation areas cover 17% of New Denham
Areas the council protects as a whole: demolition and changes to how buildings look need consent, and trees are protected.
The first, Uxbridge Lock, was designated in 2003; the newest, Uxbridge Lock, in 2006. 7 of the 9 listed buildings stand in one.

New Denham grades C for history
Protected heritage and the age of the town’s homes, against all UK towns.
Two measures, each ranked against every UK town of 1,000 or more, with protected heritage counting twice as much as the age of homes. Protected heritage counts each listed building by its grade (Grade I three points, II* two, II one), each scheduled monument and battlefield two, and each registered park or garden by its grade; it is ranked both per 10,000 residents and as a total, so a village with one fine church doesn’t outrank a historic city. The second measure is the share of homes built before 1919, from the Valuation Office Agency’s council tax records. History is a character grade: it describes the town and isn’t part of the overall grade.
9.3% of New Denham’s homes were built before 1919
Every home by when it was built, from council tax records, against England & Wales (the dark tick).
8.1% of homes are Victorian or older, against 16% across England and Wales. The busiest period since was the 1930s, which added 26% of today’s homes.
Valuation Office Agency, council tax stock of properties by build period, 31 March 2025, for the neighbourhoods (LSOAs) that make up the town, split by where their residents live. Homes with no recorded build period (9 here) are left out; 1939–44 is not a period in the data.
