London Plans

Side return kitchen, first floor & loft extension, Victorian house, London

"I would highly recommend using Jon’s services for your build. He designed our extension, oversaw our planning application, and helped us obtain quotes leveraging his extensive experience and knowledge. He was a fantastic partner throughout the whole process, going above and beyond the job spec - always on hand to advise, very cost conscious and gave the impression that nothing was too much trouble. As newcomers to building work he gave us the confidence to execute on a substantial build which has transformed our home.

At the outset Jon listened to our ideas, suggested some great ideas of his own and came up with a design that could be executed based on our budget and planning constraints in our area. He generated drawings for the planning application and his strong knowledge of regulations ensured our application was completely trouble free and permission was granted quickly. We literally did nothing as Jon oversaw the whole process. 

Jon also generated technical drawings for us which we used with builders to get detailed, comparable quotes and his advice at this stage on the best design and where to save money was invaluable. His drawings were so good that our builder now uses them on the landing page of their website.

Jon was also able to advise on structural engineers and once the build started was on hand if the builder had any questions regarding his designs.

We would definitely use Jon for any future projects and would love the opportunity to fully leverage his design capabilities."

Simple Plans The stables

First floor dormer extension with balcony and interior remodel, old stable house, Tenby

"We bought our cottage as we dreamed of living on the coast with sea views. The front upstairs room was a bathroom with a Velux window and the cottage itself unusual in design. Jonathan came to look at it and immediately could see how to change the space to create a stunning master bedroom with a balcony and fabulous sea views. The new configuration was everything we could wish for. Planners were very tricky as we are right next to a Grade 2 listed building but Jonathan spoke to them and was patient and listened and was able to come up with designs we loved and they were happy with. I cannot recommend Jonathan enough."

Ground floor kitchen extension, London

"We used Jonathan to design our single storey, side and rear wrap around kitchen extension and we’re so pleased with the results. From the very start, and in a very professional manner, Jonathan took our ideas and translated them from a rough design into a practical project. Not only did he provide invaluable ideas and insight for the project, but he suggested ways in which to make our initial design even better, and showed us how we could really maximize the space, light and impact of the extension. 
As well as providing a creative spark, Jonathan also advised us on the best use of materials and the environmental impact of these decisions, which was really important to us. 
Jonathan also advised us on building regulations and legislation, and assisted us in gaining planning permission for the build. The excellent service he provided made our build as hassle and stress free as possible, and we couldn’t be happier with the results."
