Victorian + 1930s. Planning authority: Reigate and Banstead BC.
We prepare architectural drawings across Redhill and the surrounding area — Redhill, Merstham border, Earlswood and the St John's ridge and the streets between them. The stock here is largely Victorian railway-era terraces, 1930s semis and modern town-centre apartments, with larger houses on the wooded southern slopes, and we draw for every one of those types for submission to Reigate and Banstead Borough Council.
Redhill is the commercial twin of Reigate; the Surrey Hills National Landscape (AONB) rises immediately to the south and Green Belt rings the town, so valley-floor terraces often carry Permitted Development scope while ridge and rural-edge plots face landscape tests from Reigate and Banstead. Whichever route your address falls under, we confirm it free at the measured survey and design to match the local Surrey streetscape — from period rear and side-return extensions to rear-dormer and mansard loft conversions.

Every householder application in Redhill is decided by Reigate and Banstead Borough Council, with a statutory 8-week determination. Allow around 12–14 weeks from first call to decision once the measured survey, design and validation are included. We research the council's Local Plan and recent decisions before drawing, and we hold a 98% first-time approval rate across our work.

Direct answers to what homeowners in Redhill ask about drawings, permission and fees.
Yes. Redhill (RH1, Surrey) is well within our 50-mile service radius from our central London office — about 20 miles out, 35 min from London Bridge. Every project includes an in-person measured survey at your property, so you are never charged mileage. We submit to Reigate and Banstead Borough Council through the Planning Portal.
Around Redhill, Merstham border, Earlswood and the St John's ridge, the stock is largely Victorian railway-era terraces, 1930s semis and modern town-centre apartments, with larger houses on the wooded southern slopes. We prepare planning and building-regulations drawings for every period represented, designed to match the local streetscape and satisfy Reigate and Banstead Borough Council.
It depends on your exact address. Many single-storey rear and side-return extensions on unlisted houses fall under Permitted Development, but Redhill is the commercial twin of Reigate; the Surrey Hills National Landscape (AONB) rises immediately to the south and Green Belt rings the town, so valley-floor terraces often carry Permitted Development scope while ridge and rural-edge plots face landscape tests from Reigate and Banstead. Listed buildings, flats and conservation-area properties always need full planning, decided by Reigate and Banstead Borough Council. We confirm exactly which route applies to your home, free, at the survey.
