What We Deliver

Types Of House Extensions In Sheffield

We build all types of extensions and will work with you to design the right option for your home, budget, and layout.

Side Return Extensions

Particularly prevalent in Victorian terraced homes, these extensions optimise the often-underused narrow alleyway space, creating an expansive, open-plan kitchen or dining area bathed in natural light.

Rear Extensions

Elegantly stretch your home into the garden, crafting a harmonious connection between the indoors and outdoors—perfect for spacious living areas or panoramic sunrooms.  Your family and friends will have a delightful time in this space!

Double-Storey Extensions

These vertical augmentations can simultaneously create an expansive ground-floor living space and an opulent first-floor suite, perhaps a master bedroom with sweeping views or a secluded, plush home office.

Wrap-Around Extension

A wrap-around extension combines a side return extension with a rear extension, wrapping around the existing structure. This type of extension offers extensive additional space and flexibility, allowing for the creation of large open-plan living areas, expanded kitchens, or additional rooms as needed.

The work undertaken by Jenkinson Construction has been first rate. From Richard coming round to estimate the job to Ian and his team getting on with it - I cannot find fault. They worked tirelessly, cut no corners, explained every step they were taking and involved me in every decision. Minor adjustments were gladly absorbed. They were on the job virtually every day. This was the first sauna and shower room they had built and installed, but they went about it with consummate skill and expertise. The result is better than I had ever imagined. All to budget and above board. I can recommend 100%.

Jenkinsons completed an attic extension project for us in 2025. From tender to completion the level of detail and communication was always good from Richard, Nathan and Martin. Minor changes and additions (at our request) were managed professionally and with no surprises. Nothing was a problem and all works were completed to a high standard. Big thank you to the whole team who worked on the project. Wouldn't hesitate to use Jenkinsons again in the future

Jenkinson’s did a complete house renovation for me and did an absolutely awesome job. Fantastic team who went over and above. Massive thanks to Ian who project managed everything to make everything come together seamlessly and went above and beyond to get all my requests completed, Lee who managed to make old walls covered in coral anaglypta wallpaper look like newly plastered perfectly painted walls (and was my secret interior designer) and Luke who did a fantastic job with all the joinery. Will definitely use again and would highly recommend.
