Home Extension Features & Benefits

If you’re on the lookout for house extensions that can help you reduce your energy consumption, then you’re on the right track by coming here to Bluemanor. Our double glazing utilises the latest thermally efficient glazing for a naturally warm product. By trapping heat behind vacuum-sealed glass and anti-draught mechanics, you can reduce your reliance on central heating.

At the same time, this reinforced glass will also lend your double glazing a natural strength that easily outclasses competing products. This means that you can relax, safe in the knowledge that your windows are practically just as powerful as any solid wall. This is further bolstered with high-tech locking mechanisms and Yale security in the windows and doors of your home extension.

We also have a wide range of customisation options so that you can customise your product however you like. If you have a specific colour in mind, then we’ll have it. If you have a particular shape you’re after, perhaps our Victorian or Edwardian designs, then we’ll have that too. Simply get in contact with us today or head over to our quoting engine to find out more.

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.

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.
