What type of extensions can you build?

We build single- and double-storey extensions, including projects that create larger kitchens, new bathrooms, and extra living areas. We shape the design around how you want your home to function day to day.

Will an extension look separate from the rest of my house?

A good extension should feel like part of the original home. We focus on seamless integration, so the new space works naturally with your existing layout and overall look.

Is building an extension better than moving house?

For many homeowners, yes. An extension can be a more cost-effective way to gain the space you need, while also improving your comfort and adding value to the property you already own.

In Leeds, West Yorkshire, many homeowners choose this route to avoid moving house, which brings more hassle and financial cost than it should. We focus on seamless home integration, so your new space feels like it belongs to the original property from day one.

Used PJ Builders to do a single storey extension to our bungalow. Absolutely delighted with the service we received from coming out to quote to the finished thing. We were constantly kept updated by Wayne and they were punctual and reliable. The disruption was kept to a minimum and our needs were always a priority for them, ensuring we could still use areas of our kitchen etc, for as long as possible. A must when you are living day to day during an extension project. All the tradesmen were polite, trustworthy and very good at their jobs. The finishes were excellent throughout. The suggestions regarding the velux skylights etc were really helpful and we are over the moon with the finished room! I would definitely recommend PJ Building Services. They really did take the hassle out of everything whilst delivering excellent customer service and competitively priced. The job was done very quickly and efficiently. Thank you to Wayne and all his team you will be at the top of our list for any future projects and recommendations to our friends and family

Designed to work with the way you live

Our extension work starts with the practical questions that matter most, like how you move through your home and where space gets wasted. Tailored extension designs help turn dark corners, cramped layouts, or undersized ground floors into rooms you actually enjoy using every day.

PJ Building Services can shape new areas around cooking, washing, storage, or family time to improve daily functionality, depending on what your property needs most. We provide free quotations to make it easier for you to plan the job clearly before any work begins. Our team keeps the process straightforward, offering a cost-effective space solution so you can make decisions with confidence instead of guesswork.
