A well-designed extension is one of the smartest investments you can make in your home — adding significant value and giving you the space you need without the cost and upheaval of moving. Pair it with a specialist cut roof and you also unlock the potential for a loft conversion further down the line.

No Planning Permission Needed
Most single-storey rear extensions in Poole and Dorset can be built under Permitted Development rights — meaning no planning application, no eight-week wait, and no planning fees. It's one of the most cost-effective ways to add space and value to your home.
Permitted Development (PD) is a government-granted right that allows homeowners to carry out certain building works without needing to apply for planning permission. For extensions, the key rules are straightforward — and if your project falls within them, we can typically start on site within weeks rather than months.
Single-storey rear extensions
Up to 4 metres deep for detached houses, 3 metres for semi-detached and terraced — or up to 8m/6m under the Neighbour Consultation Scheme.
Height restrictions
Maximum eaves height of 3 metres and overall height of 4 metres. Extensions within 2 metres of a boundary must not exceed 3 metres at the eaves.
No more than half your garden
The total area covered by extensions and outbuildings must not exceed 50% of the land around the original house.
Matching materials
External materials should be similar in appearance to the existing house — though this is a matter of judgement, not a strict rule.
Not in a conservation area
PD rights are restricted for properties in conservation areas, National Parks, or Areas of Outstanding Natural Beauty. We'll confirm your status at consultation.
For many homeowners in Poole and Bournemouth, a Permitted Development extension is the fastest route to more space. There's no planning application to prepare, no fee to pay, and no eight-week determination period to sit through. You get your extension built and finished in a fraction of the time — and at a lower overall cost.

Ross-Read Tip
If you're unsure whether your project qualifies under PD, we can advise at your free consultation — and if needed, apply for a Lawful Development Certificate on your behalf. This is a formal confirmation from the council that your extension is lawful, which protects you when you come to sell.
FAQ
A basic Velux loft conversion starts from around £25,000. A dormer conversion typically costs £35,000–£50,000, and a full hip-to-gable or mansard from £45,000–£65,000. We provide free, itemised quotes for all loft conversion projects.
Many single-storey rear extensions fall under Permitted Development and don't require planning permission. Two-storey extensions and projects in conservation areas typically do. We advise on this as part of our free consultation.
A single-storey rear extension typically takes 8–14 weeks from groundworks to completion. Larger two-storey projects may take 16–24 weeks. We provide a detailed timeline before work begins.
A Lawful Development Certificate (LDC) is a formal document from the council confirming your extension is lawful under Permitted Development. It's not legally required to build, but it's strongly recommended — it protects you when you sell, satisfies solicitors and mortgage lenders, and gives you peace of mind. We can apply for one on your behalf.
We manage the complete build — groundworks, structural works, carpentry, roofing, and finishing trades. You have a single point of contact throughout, which keeps projects on time and on budget.
