Home Extensions

If you want an extension, you only need one company for the job – West Yorkshire Windows. You won’t need to appoint separate builders, architects, plumbers, plasterers and fitters as we can do it all, and without any delays or additional charges. 

Having the entire project overseen by West Yorkshire Windows makes far more sense and gives you one main point of contact.

Dream Big – If you venture to one of our showrooms, you will be able to try out our 3D software and use it to design the extension. It’s a sophisticated piece of technology and let’s you visualise everything, until you reach a point where you’re happy to proceed with the real thing. 

Hassle Free – All the hassle involved in obtaining planning permission and building regulations approval (if needed) can be left in our hands.

Huge Choice – We have tried our best to provide customers with as much choice as possible in terms of the number of roofing solutions, ceilings (standard and vaulted) and windows and doors we offer.

Feel Involved – At the end of the day, the extension will be yours. You will be kept informed of any developments and be made to feel part of things.

Surprisingly Affordable – Our extensions are very affordable, especially when you use one of our payment plans, such as a monthly finance package over 5-15 years.

We take the same approach with every extension, no matter how simple or complex it will be, which is to listen intently to the customer and deliver a design that satisfies them.

Please don’t hesitate to ask our designers for their opinion on any design considerations, technical details and finishing touches. You will find that they have a fantastic insight on everything to do with extensions.

One of our consultants will also guide you when using our 3D advanced software to create your extension. You will never have imagined you could get such a realistic look at the extension before it’s even been built.

A member of our building team will get in contact with several local brick merchants to try and source a brick or stone that matches the bricks or stones your home is constructed from. They will do everything possible to find a strong match, but you need to be aware that there will be weathering differences between new and existing bricks. If our closest matching brick doesn’t satisfy you, we can tint the brickwork to help make it match, but this will incur an additional charge.

You might not have realised that there are quite so many window styles on the market and it makes choosing just one of them incredibly hard. Base your decision on your preferred window style and how you want it to perform so that your new extension fully incorporates your taste. Here is a summary of the window styles you can pick from:

Casement Windows – The casement window is one of the most classic window styles and has an unfussy appearance. Suitable for most properties, casement windows are also low-cost, secure and energy efficient, and you can also tailor the design with any colour and accessories of your choosing.

Bay Windows – One of the most characterful window styles is the beautiful bay window. Because of how it sits within a window aperture, it can add extra depth to a room.

Vertical Sliding Windows – The versatility of a traditional vertical sliding window is one of its strong points, as well as the fact that the UPVC or aluminium frame is low-maintenance.

Envisage Flush Windows – We have used traditional timber windows as a template for our ‘Envisage’ range – a modern take on the wooden flush casement. With an adaptable flush, it is most frequently used at Heritage homes and rustic new builds. 

After selecting a window style, the next decisions you need to make involve choosing a suitable frame, colour and hardware for the window. These factors collectively enable you to personalise the window design and create something that has a traditional cottage feel or contemporary look.

Value for money is assured, no matter what type of extension you buy from West Yorkshire Windows, as we supply them all with a 10-year guarantee. This guarantee keeps you covered for everything. There is no doubt in our mind that our extensions can last for at least this length of time as we construct each of them with some of the finest materials and components around. We have supreme confidence in our products, put it that way.

Added to the 10-year guarantee for the extension, you will also receive a 20-year guarantee as cover for all the windows and doors within the structure. Our design skills and manufacturing techniques ensure that our windows and doors can last for this long, if not longer. To us, it would be unfair to our customers if they had to replace the windows and doors within 5, 10 or even 15 years.
