Lawful Development Certificate in Kingston upon Thames

Kingston upon Thames is a borough of houses with long gardens, which makes the Lawful Development Certificate a practical tool here. Our drawings and submission start at £645 including VAT. Two things shape the result: the 3 Article 4 directions that cover 114 mapped areas, and the limit on how much of your plot buildings can cover.

    Three directions, many mapped areas

    Kingston has only 3 Article 4 directions, but they are drawn as 114 separate areas, which means they reach more streets than the count suggests. A direction withdraws a named right, so a house inside one may lose the right to a particular alteration while keeping the rest.

    Add 28 conservation areas, where side extensions, cladding and rear extensions above one storey are not permitted development, and the address check becomes the most useful hour of the project. We map your property against both layers, and tell you which rights are live before drawing starts.

    Historic England lists 163 entries here. A listed house still needs listed building consent, and a certificate is no substitute.

    Big gardens and the half-curtilage limit

    Residential gardens account for 30.9 per cent of all land in the borough, so many plots have room for outbuildings and rear extensions. The national rule says buildings other than the original house may not cover more than half the curtilage, and that total includes sheds, garden rooms and earlier extensions.

    So the sum matters, not each project alone. A garden room that fits on its own can tip the total over once a previous conservatory is counted. We add up everything on the plot, show the arithmetic on one sheet and present the case officer with a figure they can verify against the survey.

    Rear extensions, and when prior approval beats a certificate

    A single-storey rear extension is tested against the depth and height limits and the eaves rule near the boundary. The attached limit applies to semi-detached and terraced houses, the detached one to the rest. We measure from the original rear wall, using historic mapping where later work has altered it.

    A deeper extension can sometimes go through larger home extension prior approval. Kingston granted 3 of these in the latest twelve months and refused 35, which is a hard record for applicants. We say so honestly before you choose it. Read more under prior approval drawings in Kingston upon Thames.

    The application, its volume and its timing

    Government returns record 220 lawful development certificate applications for Kingston in the latest twelve months published. The council decides within 8 weeks of a valid application, unless it asks for more information first.

    The fee table reads: Half the normal planning fee (householder: £274), payable to the council. Householder planning is the fallback: Kingston decided 742 householder applications in its latest year and granted 83 per cent, with 92.5 per cent decided in time. Our planning drawings in Kingston upon Thames cover that path.

    Lawful Development Certificate in Kingston upon Thames: the evidence we gather

    The application rests on a measured survey of the house and the whole plot, because the coverage limit counts every building in the garden. We record the footprint of the original house from historic mapping, then each later addition, shed, garden room and outbuilding, and total them against the plot area.

    Where a previous owner built something without paperwork, we find out whether it is lawful through the passage of time or a past permission, because it still counts towards the total either way. We also note the boundary distances that the eaves rule depends on. Send us any earlier planning decisions, completion certificates and survey reports you hold, and we will use them to shorten the survey.

    What the fixed fee covers

    You receive existing and proposed plans, elevations, a section where height matters and the location and block plans. A second chartered technologist checks each sheet, and we redraw free until approval if the council asks for changes. The fee starts at £645 including VAT, agreed before we begin.

    For everything we do locally, start at architectural drawings in Kingston upon Thames. Neighbouring rules differ in Richmond upon Thames and Merton.

    Questions

    Do garden buildings count towards the limit in Kingston upon Thames?

    Yes. Buildings other than the original house may not cover more than half the curtilage, and sheds, garden rooms and earlier extensions all count. We add them up on the drawing.

    How many Article 4 directions does Kingston upon Thames have?

    3 directions, covering 114 mapped areas. We check your address against them.

    How long does Kingston take to decide a certificate?

    The statutory period is 8 weeks, which a request for information can pause.

    What does the council charge?

    The fee table reads: Half the normal planning fee (householder: £274). Our fixed fee starts at £645 including VAT.

    Does an old conservatory count towards the limit?

    Yes, if it is still standing. Every building other than the original house counts towards the half-plot cap, lawful or not, so we measure and total each one before we draw anything new.
