We cannot recommend Ken and Jackie Coleman highly enough, right from the initial site meeting and consultation with Ken to where we are now having received Planning Consent and just been given full Building Regulations approval and ready to start our project. JLS also recommended our builder!!

During our journey with JLS we have been constantly kept up to date every step of the way, not just by email and telephone but backed up with hard copies posted and received the next day which in itself is rare these days but also shows a very good old fashioned approach which in our view puts JLS in a league of their own, even minor hurdles were dealt with in the most effortless professional manner imaginable.

We cannot thank you and your team enough and feel privileged to have found you.

I have used JLS Design Services for 5 of my projects now for both my home and investment properties- this has ranged from small extensions to a new build.  Without fail Ken and Jackie have been continually supportive and always listen to my ideas and requirements – which is clear from the designs produced.  They are always open to the odd change or tweak to the design if needed and Ken’s input is invaluable in getting to the best solution.  

They take the load off dealing with the council from planning to building control – and Jackie answered any questions I had regarding any of the processes promptly.  

I sincerely thank them for sharing their knowledge and for their continual support.  The encouraging approach they have had on each of my projects and to me has made the experience with JLS Design such a positive one – and one which I hope to continue with in the future.  I recommend them to anyone thinking of improving or building their home.

Dear Ken and Jackie
“I could not have found a better partnership to take on the architectural and planning process and I knew right from the start that I was in safe hands. Apart from the hiccup over the restrictive covenant on my property (a complication beyond your control), everything progressed with minimum fuss and maximum efficiency, leaving me in no doubt that I’d made the right decision to enlist your help. Your professionalism, together with the warmth and good humour of the many telephone conversations we had, were for me, a winning combination. Thank you for your ever-patient, positive, helpful and cheerful response to my questions and requests. It was both remarkable and very reassuring and I applaud you for the way you look after your clients. To my great relief, the process turned out to be not just simple and straightforward but also interesting and even, at times, fun! Getting to know you both has been a delight, so I can’t help but feel sad that I no longer have cause to ring you for advice. Your service has been outstanding and you have done me proud. I am immensely grateful.
My warmest regards to you both.”

Mrs E Makeham – Nailsea, North Somerset


We found JLS Design Services in the local press. We had already been through design and planning with another architect but, after the planning permission expired we decided we wanted to take a fresh look at the potential of our home. 
From start to finish both Jackie and Ken were engaged in the process and kept us up to date with developments with the various applications that were required and how plans were progressing. Ken was always patient, positive and constructive with the numerous alterations we made before finalising our plans and always came across as genuinely excited at what was to be carried out with our home. 
When issues arose on site Ken was happy to come out and speak with the various contractors to resolve issues, drainage being one, and find solutions that could be put in place. The end product is literally our dream home. Ken sympathetically balanced our old cottage with the new build to maintain the character and feel of an old house and we love the end result. We have, and will recommend JLS Design Services to anyone who is looking to build or improve their home. 

Mel and Justin Andrews – Portishead, North Somerset


“When sketching out what our extension should be, how it would suit our plot and what we wanted to achieve from it, we consulted 3 practitioners. You were the only one who listened and assisted in making our vision become a reality. You were extremely patient with the various iterations we went through and more importantly, you made both of us feel involved with the process of the design, leading to the ultimate success in gaining our planning permission. We love the space that you have helped us created for our family and would have no hesitation in recommending you to others thinking of enlarging their homes.
Many thanks for all you did for us.”

James & Lucy – Yatton, North Somerset 


“I would like to take this opportunity to say a big thank you to both yourself and Ken. We are very pleased with your service, experience and professionalism.
We have been complimented on the detailed plans from our builders and as I
have already mentioned heard good reports from other agencies. I would not hesitate to recommend your services to friends and family.”

Tracy & Stuart – Nailsea , North Somerset 


“We have nothing but the highest praise for Ken & Jackie. Their service has been faultless and they really managed our entire project perfectly well. They squeezed us in for an appointment really quickly and were quick to respond to any emails/messages. The advice they gave us was fantastic and we felt they were truly committed to making our project the best it could be. We can only thank them and recommend them to anyone- we will certainly use their services in the future.”

Mrs Stenzel – Brentry, Bristol


“Really pleased with the service and design we received, extremely friendly and knowledgeable company, we would not hesitate to recommend”

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


“Working closely with JLS Design Services is made incredibly easy by Ken’s attention to detail, positive and professional attitude, and precision in all that he does. 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 – Nailsea , North Somerset


“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


“We would fully recommend JLS Design Services for their designing of our new porch and for their guidance throughout the whole process, giving us complete peace of mind. We received a fully professional and friendly service,giving us every satisfaction.”
