Totteridge: drawings for conservation area and Green Belt homes

Totteridge layers a conservation area over land that is also recorded as Green Belt, and its appraisal cares about hedges, walls, sash windows and clay or slate roofs. We prepare planning, listed building and Building Regulations drawings that address both layers, after a free constraints check.

    04The brief

    Two designations on one street

    Totteridge is Barnet's conservation area CA12 in the planning.data.gov.uk conservation-area dataset. planning.data.gov.uk records the Totteridge conservation area as intersecting Barnet's Green Belt.

    Barnet publishes 16 conservation areas, and Green Belt polygons cover 28% of its area. When both apply to one house, we check each before drawing, because each can change what is acceptable.

    05The detail

    Two kinds of Article 4 direction

    planning.data.gov.uk records Article 4 and Article 4(2) direction areas made for the Totteridge conservation area (Article 4 Areas 1 to 3 and Article 4(2) Areas 1 and 2). planning.data.gov.uk also records Article 4 agricultural land restriction areas intersecting the Totteridge conservation area.

    The register shows more than one direction for the area, each with its own mapped areas, so the wording that applies to your house depends on its location. We read the direction for the exact address and quote it in the covering letter.

    Boundaries, windows and roofs

    The appraisal is specific about the details it expects to see kept. New or replacement boundary features must respect the informal green character; big houses have high walls and hedges, small ones low walls. Predominant windows are timber vertical sliding sashes with recessed openings; mixed pane sizes are typical.

    Roofs are hand-made clay tile or Welsh slate; Welsh slate (about 22 degrees) dominates mid-19th century and later buildings. A re-roof or replaced windows are therefore drawn in matching materials, with the existing pattern shown beside the proposal.

    Hedges, mature trees and the listed houses

    Barnet holds 718 tree preservation orders, and the appraisal expects high walls and hedges round the big houses. We plot hedges and trees on the survey before an extension is sited. The borough also lists 651 entries, and in its latest year it decided 76 listed building consent applications and granted 93.4% of them.

    Those figures record what Barnet has decided before and do not forecast your application. A listed house starts with listed building consent drawings. A new roof storey is seldom the answer on a Green Belt villa, and mansard roof drawings shows how we test one first.

    Questions

    Is my Totteridge house in the conservation area and the Green Belt?

    The national planning data records the Totteridge conservation area as meeting Barnet's Green Belt, but your address may sit in one, both or neither. Send it to us and we check both, plus Article 4 directions and trees, before quoting.

    Why do two kinds of Article 4 direction matter to a Totteridge extension?

    planning.data.gov.uk records Article 4 and Article 4(2) direction areas made for the Totteridge conservation area (Article 4 Areas 1 to 3 and Article 4(2) Areas 1 and 2). Each covers its own mapped areas, so your house may sit under one, both or neither. We read each against the address and quote the wording in the covering letter.

    What does a listed house in Totteridge need beyond planning drawings?

    Listed building consent, with drawings that record each original feature and show what the work touches. If the house also lies in the Green Belt, the planning application answers that separately, so we prepare the two sets to agree. The route is on the listed building consent hub.

    How are fees set for a Green Belt extension in a Totteridge conservation area?

    A roof storey is seldom the answer here, so the usual job is an extension, and its quote covers the Green Belt test and the appraisal together. The fee is fixed, VAT included, and agreed after the free constraints check. Basement drawings begin at £1,995.
