Mr & Mrs Graves – Yatton, North Somerset


“We employed the services of JLS Designs for a combined kitchen extension and garage conversion. From the outset we found Ken and Jackie to be very informative, knowledgeable, professional and friendly. The plans were very detailed and accurate and the help they gave us with the planning applications/building regulations, and dealing with the water company, was invaluable. As the build progressed they were always available to help with any queries and decisions, and to liaise with our builder when required. We have no hesitation in highly recommending JLS Design Services and look forward to using them again in the future”

Mr & Mrs Gifford – Yatton, North Somerset


“JLS have been professional, reliable and efficient dealing with our new house extension.  Ken worked with us initially to ensure that the look we were after was realised in his plans.  He assisted greatly in shaping our ideas of a single storey extension with a large glass lantern-light roof, and ensuring that they were achievable within the current building regulations.  We made minor changes to the original plans, which were dealt with swiftly.  The planning department requested changes, which JLS dealt with immediately.  All communication with the council and the water company was dealt with by JLS and so the process of getting to the build stage was straightforward and stress-free, and all completed within 4 months of our first meeting with Ken.  

Well worth every penny.”

“Now we are enjoying life with our new extension within 6 months of having the idea.  I can’t recommend JLS highly enough! -Thank you!”

Mr & Mrs Warren – Cleeve, North Somerset

Ken and Jackie are approachable and have impeccable customer service skills, always having the answer to any question posed. The plans are always produced to the highest of standards, incorporating all detail and precision required by us as a construction company.

If you are seeking an experienced, professional architectural designer for your project, be it small or large, we would have no hesitation in recommending JLS Design Services. You will not be disappointed.”

Mendip Construction (SW) Limited  – Bristol


“We loved working with JLS Design Services to plan our home improvements. Ken visited us to understand our needs and put so much care and effort into designing what we wanted. He was flexible and open to our ideas and added his own experience and suggestions to create great designs. Jackie made sure everything ran smoothly. She handled paperwork professionally and efficiently and regularly kept us up to date with progress.

Thanks to them and a good builder we have a fantastic house as a result!”

David & Helen – Henleaze, Bristol
