If you’re extending or building a new home in Oxfordshire, Berkshire or the Cotswolds, navigating planning permission can be one of the most important parts of the journey. And if you get it wrong, it could cost you both time and money.
At Black Swan Architecture, we guide you through planning with experience, insight and care. Whether your home is listed, located in a conservation area, or you’re working under permitted development rights, our approach helps you move forward with confidence.
When Planning Permission May Not Be Required
Some extensions and home upgrades may fall under permitted development (PD) rights:
- Single-storey Rear Extensions within specified size and height limits
- Loft Conversions using roof lights or dormer windows
- Outbuildings, like garden rooms or home offices, that fall within permitted size and placement guidelines
However, these rights are not universal. PD generally does not apply to:
- Listed buildings
- Flats or maisonettes
- Properties in protected areas such as AONBs or conservation zones
We always recommend a thorough planning check, even if your proposal seems straightforward.
When Full Planning Permission Is Required
You’ll need planning permission for:
- Two-storey extensions or significant internal reconfigurations
- All new-build homes
- Inspection work on listed buildings (plus listed building consent)
- Any design changes that significantly affect the external appearance of your home
Our role is to manage applications, liaise with planning officers and ensure your design aligns with both your aspirations and the local context.
How We Improve Your Chances of Success
We adopt a smart, considered approach to planning strategy. That includes:
- Seeking pre-application advice to clarify potential issues early
- Commissioning heritage or landscape assessments where appropriate
- Maintaining active communication with local authorities
- Producing design-led applications that make a compelling case
Whether building on a countryside plot or extending a Georgian farmhouse, we ensure your project respects regulations while reflecting your vision.
