Whether you want to add space, increase value, or improve its functionality, here are six strategic ways to use permitted developments rights to maximise your property’s potential:
1. Rear Extension (Single or Double Storey)
Creating extra space at the back of your home is one of the most impactful uses of PDR.
What’s permitted:
- Single-storey: Extend up to 6 metres (semi-detached) or 8 metres (detached) from the original rear wall, subject to prior approval.
- Double-storey: Extend up to 3 metres, with a minimum 7m distance to the rear boundary.
- The extension must not exceed the height of the original house.
Coverage Limit
No more than 50% of the land surrounding the original house (as built or as it stood on 1st July 1948) can be covered by extensions or outbuildings.
Why it works: Perfect for open-plan kitchen / dining areas, family living areas, or dining extensions. We’ve helped many clients create high-quality and functional spaces – without needing full planning consent.
2. Side Extension (Single Storey)
Side extensions are ideal for homes with unused space to the side and accommodate a utility room, garage, or shower room. The front façade cannot be changed.
Key PDR considerations:
- It must be single storey
- No wider than half the original house
- Not closer to the road than the main front elevation.
- The maximum height does not exceed 4 metres.
Why it works:
Adds valuable practical space without compromising the original layout. Light House Studio can help design an integrated and elegant side extension that fits seamlessly into your home and respects your property’s character.
3. Loft Conversion with a Dormer
Loft conversions are one of the most cost-effective ways to transform unused attic space into extra space without expanding your home’s footprint.
Under PDR you can:
- Add a rear dormer up to 40 m³ (terraced) or 50 m³ (semi/detached)
- Install roof lights or Velux-style windows
Design rules: Must sit at least 20 cm below the original eaves, not exceed the current roof ridge, and not overlook neighbours
Why it works:
Turn unused attic space into a bedroom, home office or creative studio. We’ve helped clients across Hampshire realise the full potential of their lofts - boosting space and property value.
4. Convert an Integral Garage into Living Space
Many garages go unused or become cluttered storage spaces. PDR allows you to convert integral garages into functional spaces and habitable rooms without needing full planning permission, provided you don’t change the external footprint.
What’s allowed:
Conversion of integral garages into habitable rooms, as long as the external footprint remains unchanged.
Why it works: A practical and more budget-friendly way to create an extra bedroom, playroom, utility or home gym. It utilises existing space efficiently, adding functionality and value.
5. Add a Garden Room or Outbuilding
Create a dedicated workspace or retreat in your garden under permitted development rules.
PDR permits:
- Single-storey outbuildings
- Maximum height: 2.5 metres if within 2m of a boundary
- Cannot cover more than 50% of your garden
- Use must be incidental (e.g. home office, gym, studio—not a separate dwelling)
Why it works:
Ideal for remote work, creative hobbies, or private retreat spaces. We’ll design a garden structure that complements your home’s style and enhances outdoor living.
6. Front Porch Extension
Make a strong first impression and add practical space at your entrance.
Permitted if:
- Floor space is under 3m²
- Height does not exceed 3m
- Minimum 2m from a highway boundary
Why it works:
A great first impression and functional space for coats, shoes or packages. We can create a welcoming design that fits your home’s character.
⚠️ Pro Tip: Understand the rules and know the Limits
At Light House Studio, we guide clients through the compliance and feasibility side of PDR. Here are some key things to check.
Here’s what to keep in mind:
- Conservation areas & Article 4 Directives: These can restrict or remove PDR. Always check with your local authority.
- Ineligible properties: Flats, maisonettes, listed buildings, and homes in conservation areas may not qualify for PDR.
- Certification: Apply for a Lawful Development Certificate (LDC) to formally confirm that your proposed work is permitted.
- Neighbour impact: Larger extensions may require prior notification and neighbour consultation via your local council.
