House Extensions Brentwood

If you are looking for the ultimate way to not only expand the space in your home, but add value to your property, look no further than a house extension. It is a lifelong investment in the future of your home and will create a year round, cosy space that will give you the extra room you have always dreamed of.

There are several reasons why homeowners throughout Brentwood continue to add house extensions to their homes. Not only do they deliver a whole host of performance benefits, but our double glazed designs will fill your space with natural light and allow you to enjoy the best of both being inside and enjoy a bright space. One of the benefits house extensions have over conservatories is that they deliver the maximum amount of thermal performance as well as added privacy with larger brick built areas.

If you are looking to add a house extension to your Brentwood home, you have come to the right place. Here at Bluemanor, we have been enhancing homes in Brentwood and throughout Essex for many years.

Fantastic Insulation & Robust Security

House extensions offer great insulation, being one of the main reasons that homeowners will usually choose a house extension over a conservatory or orangery. This means that not only will your new extension add style to your Brentwood home, it will also deliver unrivalled thermal performance, meaning your indoor space is warmer for longer, lessening the need to use your central heating. It retains warmth inside, making it the perfect year-round space.

Here at Bluemanor, we understand that the safety of your priority is one of your main priorities. Our house extensions are supplied to us from highly regarded manufacturers, meaning that they are constructed using resilient double glazing and high security locking mechanisms. Whatever configuration you choose, you can rest assured that our designs will keep your home safe.

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.
