CAD / Drawings- 20 Aug 2019
I hired Mr Simon Javens of JavensDesign and found him to be very professional and able to turn around a difficult planning application accurately and quickly complete with fully CAD design specifications. He is willing to go the extra mile to liaise with third party agencies, be it the Council or previous structural surveyor(s) and architect(s). A very pleasant chap indeed. You will not regret hiring his services. I received excellent advice in every step of the journey - Simon is very knowledgeable and willing to help.

Bathroom Fitting- 26 Feb 2026
Worst job ever. The first day he came at 10.30am started the job left at 9pm said it would take a day & a half. The next day he said he would be here at 8.30am again he came at 10.30am & his words were I’m going to finish in 2 hours maximum. By 3pm he still hadn’t finished & I heard him speaking to someone on the phone saying that he would be there in 45 minutes.then he told me he needed a part for my job & he would be a couple of hours, he came back 4 hours later without a part.Again he was here till 9.30pm. He said he had finished. I went to look and his work was bad. I complained he said he would come back the next day. the next he said he had finished & I told him I wasn’t happy he came back the next day. He tidied up his mistakes.he shaved the bottom of the door off a bit as it wouldn’t close coz of the new tiles & he left, as he was leaving he said please give me a good review. I said I’ll tell the truth & he said but the truth isn’t good. He didn’t stick the threshold back on.
