When we decided to have our conservatory roof replaced we looked around & the quality & process of Bluemanor was not the cheapest but by far the best. We decided to have the windows & doors replaced as well & the whole process every trade was excellent friendly & arrived on time. The conservatory is more than we expected not hot not cold & looks amazing. Thank you Bluemanor Team.

Colin Jenkins

First class service. Quibble free replacement of misted glass pane towards the end of the 10 year guarantee on double glazed units purchased for the whole house. Able to match existing window design if so desired but can easily offer modern designs with appropriate advantages.

Frequently Asked Questions

Are house extensions expensive?

Being a full brickwork extension of your property, they naturally come at a greater expense than a conservatory. However, it can still often be much more cost effective and less stressful than upsizing to a new property.

Better yet, we offer a range of finance terms, if you’d prefer to spread this cost. Contact us today to discuss this in further detail. Subject to application and acceptance.

House extensions won’t require a planning permission application providing they adhere to what makes a ‘permitted development’. We can advise of these, as well as building regulations, during our initial design meeting with you at our showroom in Braintree, Essex.

You are welcome to design an extension that goes beyond permitted development rules, but you’ll have to apply to local building authorities. You may also have to apply regardless of size or placement if you live in a conservation area.

They are! You won’t be making a compromise on your home security by extending its floorplan. Any external windows and doors will be fitted with multipoint locks as standard. This includes high quality systems from Yale.

We also only use the most robust materials from leading extruders, such as Liniar, Smart and The Residence Collection. Extend your home with Bluemanor and have peace of mind.

We are! Our expert team are registered Ultra Installers, so you’re in good hands when we build your house extension. We’re also backed by FENSA, the Which? Trusted Trader scheme and Buy With Confidence, to name but a few.
