Listed building consent drawings for Barnet's heritage houses

Barnet's best-known heritage is landscape as much as buildings: the Totteridge conservation area, which runs into the Green Belt, and Hampstead Garden Suburb, covered by two Article 4 areas. A listed house in either place is read against its surroundings as well as its own walls. We record the fabric first, then draw what the proposal keeps and alters, so the officer can test both.

    02The brief

    Totteridge: what the appraisal says the place is made of

    Totteridge's own character appraisal reads like a materials list, and a consent drawing has to speak the same language. On roofs it records: Roofs are hand-made clay tile or Welsh slate; Welsh slate (about 22 degrees) dominates mid-19th century and later buildings. On windows it records: Predominant windows are timber vertical sliding sashes with recessed openings; mixed pane sizes are typical.

    Boundaries count too. The appraisal puts it this way: New or replacement boundary features must respect the informal green character; big houses have high walls and hedges, small ones low walls. Our existing-condition sheets note which of these features survive on your house, so a later change reads as a decision and not as an accident. The wider area is covered in architectural drawings in Totteridge.

    06The detail

    Hampstead Garden Suburb: designed as one piece

    The Suburb sits in Barnet's list of conservation areas as Hampstead Garden Suburb, and it is covered by two separate Article 4 directions. The planning data names them as "Article 4 for Hampstead Garden Suburb CA, Area 1 (ref A4D4)" and "Article 4 for Hampstead Garden Suburb CA, Area 2 Spaniards End (ref A4D4A2)".

    In practice that means ordinary permitted development cannot be assumed on any Suburb street, and a listed house there faces consent on top. We read the list entry, the conservation area and both directions together before we quote.

    Counts, costs and the order of work

    Across the borough Historic England records 651 list entries, with 16 conservation areas and 15 Article 4 directions around them. Barnet decided 76 consent applications in its latest published year and granted 93.4% of them.

    National policy supplies the test where the council quotes none: Proposals affecting heritage assets need an assessment of significance (including setting) proportionate to the asset's importance, and on weight it is blunt: Substantial weight to the conservation of designated heritage assets. The consent application attracts no council fee. Garden structures need care, since Garden buildings within the curtilage of a listed building are not permitted development.

    When the house wants a new roof or a cellar

    Works to a listed house often come with a roof or lower-floor proposal. Those are covered by mansard roof drawings in Barnet and basement conversion drawings in Barnet, and we draw them from the same survey as the consent set.

    Questions

    Can I replace the windows in a listed Totteridge house?

    Usually only with consent, and the appraisal's note on windows explains why officers care: Predominant windows are timber vertical sliding sashes with recessed openings; mixed pane sizes are typical. Send the address and photographs, and we check the entry before advising.

    Is Hampstead Garden Suburb the same thing as a listed building?

    No. The Suburb is a conservation area with Article 4 directions, and individual houses may or may not carry a list entry. They are separate controls, and a house can have either, both or neither.

    Does Barnet decide many listed building applications?

    It decided 76 in its latest published year and granted 93.4% of them. The figures describe past decisions and say nothing about a particular house.
