A glazed extension that adds real living space
A conservatory extension is a mainly glazed room built onto the rear or side of your home, usually with a dwarf brick wall, large glazed panels and a roof made from glass, polycarbonate or a solid warm-roof system. Modern conservatory extensions are a world away from the cold, leaky rooms of the past.
With good glazing and a warm roof, a conservatory works as a true year-round room. Homeowners use them as kitchen-diners, family snugs, home offices and playrooms. Because much of the structure is glass, you get a bright, open feel that connects the house to the garden.
A conservatory extension sits between a lean-to porch and a full brick rear extension. It costs less and goes up faster than a solid build, while still adding a proper room you can use every day.
Best For
Homeowners who want extra light-filled living space quickly and affordably, without the cost and time of a full brick extension.
Typical Build Time
Most conservatory extensions are completed in 3 to 6 weeks, depending on size, roof type and groundwork.
Why choose a conservatory extension
- Lower cost per square metre – a glazed extension is usually cheaper than a fully bricked build for the same footprint.
- Faster to build – less groundwork and brickwork means most projects finish in weeks, not months.
- Floods the home with light – large glazed panels and a glass or lantern roof bring daylight deep into your house.
- Year-round comfort – modern warm roofs and A-rated glazing keep the room usable in winter and summer.
- Often permitted development – many conservatories can be built without full planning permission.
- Adds value and appeal – a well-built, warm conservatory is a strong selling point for buyers.

Do you need planning permission?
Permitted development rules
Many conservatory extensions fall under permitted development, meaning full planning permission is not needed. As a general guide in England:
- Rear extensions on a detached house can extend up to 4m (up to 8m under prior approval); 3m for other houses (up to 6m under prior approval).
- The extension must not cover more than half the garden or land around the original house.
- Height limits apply, and rules are stricter on listed buildings and in conservation areas.
- Building regulations may still apply depending on glazing, heating and how the room links to the house.
We check the rules for your property during the survey and handle any approvals for you, which is how we keep our 100% planning success rate.
Good To Know
Adding fixed heating or removing the dividing doors between the house and conservatory can change whether building regulations apply. We advise you on the best set-up before work starts.

What our customers say
Real reviews from Nottingham homeowners.
We went for a warm roof and it made all the difference. The conservatory is cosy in winter and we use it every day as a family room. Tidy team and finished on time.
They turned the back of our house into a bright kitchen-diner conservatory. The glazing is superb and the quote was exactly what we paid. Really happy with it.
From the survey to handover everything was clear and professional. They sorted the permitted development check for us and the lantern roof looks fantastic.

You can choose a glass roof for maximum light, a lantern roof for a feature look, or a solid warm roof for the best insulation. We help you pick the right one for how you plan to use the room.
Most projects take between 3 and 6 weeks from starting on site. Larger builds or those needing more groundwork can take a little longer, and we give you a clear timeline in your quote.
Yes, many homeowners open the conservatory directly into the kitchen to create a large kitchen-diner. This can affect building regulations, so we advise on insulation and heating to keep it compliant and warm.
