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.
How Long Does a Loft Conversion Take?
Most loft conversions take 6-12 weeks, depending on complexity and the level of change required. Those needing structural alterations will naturally take longer than an internal conversion.
Do I Need Planning Permission?
Some conversions fall under permitted development. This is usually completed by the architect during the design phase of the project. If you don’t have an architect yet – we have an extensive book of building professionals who we’ve been working with for years, and can advise you on the best fit for your project.
What if it Rains During Construction?
We plan for weather interruptions ahead of time, and protect your home with waterproof sheets and covers to protect the inside of your home.
We also offer and, in most circumstances, recommend installing a scaffold canopy. This allows a lot more protection in adverse weather and allows continuous work in all weather conditions.
Can You Work on Listed or Older Buildings?
Yes. We specialise in structural alterations and sensitive work for heritage properties.
Can You Install a Bathroom in My Loft?
Yes, we can provide full wet room or bathroom installations as part of your installation. Simply let us know during the consultation stage, and we’ll advise on the best solution for you.
