Architectural drawings for homes in Barnes

Barnes sits in a bend of the Thames, and its houses are controlled by conservation areas, Article 4 directions on named roads and the ground itself. We draw for all three, beginning with a free check of your address before any design time is spent.

    04The brief

    Barnes Green, Mill Hill, Castelnau and the Common

    The village is divided into areas that carry separate rules: Barnes Green, Mill Hill, Castelnau and Barnes Common. Barnes Green Conservation Area was designated on 14 January 1969 and extended in 1982, 1988, 2004 and 2018.

    The Barnes Green Conservation Area appraisal was adopted on 8 February 2024. That appraisal is the document an officer reads a Barnes Green scheme against, so we work from its wording rather than a general rule.

    05The detail

    Where Article 4 reaches in Barnes

    Richmond Council lists Article 4 Directions in Barnes Green Conservation Area (CA1) covering Bellevue Road, Glebe Road, Hillersdon Road, Laurel Road, Ranelagh Avenue and The Crescent, and in Castelnau (CA25) covering Castelnau Row. On those roads, work that is normally permitted development needs an application.

    Classes removed are not stated on the council list page; the page says Article 4 directions cover extensions, new doors and windows, painting brickwork, removing chimneys, replacing front gardens and boundary walls with hard surfaces. If your road is named, we plan the application round it from the start; if it is not, we confirm that before design begins.

    A low, wet site shapes the design

    The council's Barnes Green appraisal describes Barnes as sitting within the meander of the Thames in an area of flat, low-lying floodplain. For a rear extension or a lower-ground room, the first questions are levels and drainage, and our measured survey records them.

    Work below the ground floor follows its own test: see basement conversion drawings in Barnes. A basement starts at £1,995, VAT included.

    Listed houses and the wider borough

    Richmond upon Thames holds 819 list entries, 40 of them at Grade I. For a listed Barnes house, listed building consent drawings in Barnes cover the consent that runs beside planning.

    A new roof storey is read against the neighbouring roofs: our mansard roof drawings in Barnes page explains the test. Further up the river, Kew and Richmond are covered the same way.

    Questions

    Is my Barnes road under an Article 4 direction?

    Richmond Council lists Article 4 Directions in Barnes Green Conservation Area (CA1) covering Bellevue Road, Glebe Road, Hillersdon Road, Laurel Road, Ranelagh Avenue and The Crescent, and in Castelnau (CA25) covering Castelnau Row. We confirm your exact address against the register during the free constraints check.

    Does flood risk affect an extension in Barnes?

    It can. The council's Barnes Green appraisal describes Barnes as sitting within the meander of the Thames in an area of flat, low-lying floodplain. We record levels in the survey so the design starts from the real ground.

    How much is a mansard or basement in Barnes?

    A mansard starts at £845 and a basement at £1,995, including VAT. Council fees are separate.
