We’ll confirm if your idea is Permitted Development or needs full planning — and what to do next.
High Wycombe at a glance
High Wycombe sits within Buckinghamshire Council’s planning authority. Many small home projects can proceed under Permitted Development (PD), but local controls — especially Article 4 Directions and conservation areas — remove or limit PD in parts of the town. If your proposal pushes beyond PD limits, affects a heritage setting, or changes access, you’ll need a full planning application.
- Check PD first, then local constraints.
- Budget for drawings, fees, and 8–10 weeks for a decision.
- Use the council’s online register to check nearby approvals.
Quick answer: do you need planning permission?
If your extension or alteration in High Wycombe stays within PD limits for size, height and position, you may not need full planning. You will need permission if you exceed PD, live in a flat/maisonette, your property is listed or in a conservation area, or you’re altering access (e.g., dropped kerb).
For a wider context, see our pillar guide: Planning Permission (UK) and our county hub: Planning Permission Buckinghamshire.
Rules & checklist (what to check first)
1) PD basics homeowners ask about
- How far can you go out without planning permission? Rear extensions at many houses have depth limits; larger depths often need “Larger Home Extension” prior approval. See Extension rules.
- Maximum height without planning permission: Eaves and overall height are capped under PD and depend on roof type.
- How high without planning permission? Two-storey works and raised platforms typically need permission.
2) Property type & location
- Flats/maisonettes: PD is very limited — assume you’ll need permission.
- Corner plots / highways: New access or visibility splays may require consent and highways input.
- Conservation / Article 4: PD rights can be removed; even minor alterations may be controlled.
3) Where to check live applications
- View planning applications in High Wycombe (council map/register)
- Use “search by address” or map to review decisions, officer reports and conditions.

Local quirks: Article 4 & conservation
Parts of High Wycombe sit within conservation areas and Article 4 zones. Article 4 Directions remove automatic PD rights to protect local character — for example, controlling front elevations, materials, and roof profiles. Expect tighter scrutiny on design, glazing patterns and materials where streetscape is sensitive.
- Respect ridge heights and roof pitches visible from the street.
- Keep materials and window proportions consistent with the host house.
- Provide a short design rationale with your drawings if close to heritage assets.
Costs & timelines
- Application fee (householder): typically ~£258 (confirm latest on Buckinghamshire Council).
- Decision target: 8 weeks from validation (complex or heritage sites can run longer).
- Drawings: accurate plans/elevations + site plan are essential for smooth validation. See Planning Permission Drawings – Complete Guide.

Case study: Rear kitchen extension near a conservation area
A homeowner in High Wycombe wanted a single-storey rear kitchen extension. On paper the depth matched PD, but the plot sat within an Article 4 area close to a conservation zone. We recommended a full application with clear, scale-checked drawings and a short design note explaining materials, roof pitch and window rhythm. The proposal gained approval in just over 8 weeks with standard matching-materials conditions.
