    A recent local plan and fresh design guidance

    The Mole Valley Local Plan 2020-2039 was adopted in 2,024 and replaced the old Core Strategy, so the policies in force are current and the council expects schemes to follow them closely.

    Design guidance is just as new. The Design Guidance for House Extensions SPD is the document officers open for rear, side and roof additions. Alongside it sit the Design Code SPDs (Ashtead; Bookham & Fetcham; Dorking Parts One and Two; Leatherhead), each setting out local character for a named town.

    The practical effect is that we draw to the design code for your settlement, not to a generic standard. Materials, roof pitch, plot rhythm and boundary treatment are all read against the code for your own town, and our elevations show the relationship plainly.

    Green belt, listed buildings and open land

    With 76 per cent of the district in the green belt, many houses stand on land where national policy limits disproportionate additions. The test compares the size of the building after the work with the original. We measure the original footprint and volume early, so we can tell you how much room is left.

    Heritage is dense for a rural district. Historic England lists 1,013 entries: 6 at Grade I, 51 at Grade II* and 954 at Grade II. A further 27 scheduled monuments, 5 registered parks and gardens and 7 entries on the Heritage at Risk Register show how much of the landscape is protected. The council names 11 conservation areas.

    If your house is listed, most alterations need listed building consent as well as planning permission. Tell us at the first call and we will explain which route fits.

    Homes, owners and prices in the district

    The Census counted 37,139 households, and 77.7 per cent of them live in a house or bungalow. Owner-occupation stands at 73.2 per cent, a pattern that favours family-sized extensions over flat conversions.

    Land Registry figures show an average detached price of £993,822, against £453,154 for a terrace. Detached houses on large plots sit at the upper end, and that is where green belt arithmetic bites hardest.

    Timing and outcomes on Mole Valley householder cases

    In the latest twelve months the council decided 488 householder applications and granted 76.6 per cent. Only 73.2 per cent were decided within eight weeks or an agreed extension, so a good share ran longer.

    Plan for that gap. If your builder's start date matters, allow extra weeks, and ask us to submit a complete set first time so the case is not delayed by a request for more information.

    Prior approval for larger rear extensions has been used here, with 3 granted and 7 refused in the latest year of returns. That mix is a reminder that the neighbour-consultation route is not automatic. Over the same year the council issued 163 lawful development certificates.

    Building in a village or the open countryside

    Outside Dorking and Leatherhead, many homes sit in villages and hamlets, where the visible test is how a new extension reads from the lane. We therefore draw a view along the road as well as the usual plans, and we test the roof form against the houses either side.

    Rural plots bring practical questions too. Some properties rely on private drainage, trees and hedges carry weight in the character of the lane, and an old outbuilding may be a candidate for conversion. We list these points in the first summary so you can budget for specialist surveys.

    Extending a period home

    Older houses on the edge of Dorking and Leatherhead often have thick walls, timber frames or irregular floor levels. We measure these with care, because a drawing based on assumed squares will not survive a builder's first visit.

    If the house is listed or in a conservation area, we write a short statement explaining what is original, what is changing and why. A clear statement helps the council's heritage officer reach a view without another round of questions.

    For a modern house on a larger plot, the work is usually about proportion. The question is how far a family can grow the building before the green belt rule begins to bite, and we build the answer into the first design option rather than the last.

    Costs, timing and what to plan for

    Allow for the application fee, any specialist reports, the building regulations stage and, once the permission is in hand, the build itself. We set out the likely reports at the start, such as a tree survey or an ecology check, so that nothing arrives late.

    Because a share of decisions here ran past eight weeks, we suggest you sequence the building regulations drawings while the application is with the council. That way the technical sheets are ready on the day the permission arrives.

    Questions

    Does the green belt stop me extending my house in Mole Valley?

    Not automatically, but about 76 per cent of the district is green belt and additions must not be disproportionate to the original building. We measure the original and tell you the room left before you spend on design.

    How much do architectural drawings cost in Mole Valley?

    Householder planning drawings start at £745 including VAT, fixed and published. The council's application fee is paid to the council separately.

    Which guidance does Mole Valley use for house extensions?

    The Design Guidance for House Extensions SPD, together with the Design Code SPDs (Ashtead; Bookham & Fetcham; Dorking Parts One and Two; Leatherhead) for your town. We draw against both.

    How long does Mole Valley take to decide a householder application?

    In the latest figures 73.2 per cent were decided within eight weeks or an agreed extension. That is a record of the past, so allow time in your build programme.
