Some of my visitors' comments
  • "I couldn't find anywhere to send you a feedback on your site, what a life saver site, just the questions I had in mind and had been calling around friends to get answers and found your site, definitely you are right on entire net no site takes into the process like you did in easy language and explained remarkably well. I must say clap clap excellent thought and done well too and extremely helpful, I am ever so grateful."

  • "That is one good website with a vast knowledge of useful information, which has answered many of my questions and which I will revisit many more times."

  • "I Googled 'How to build and extension' and your site was top of the list. What a fantastic site it is too. I've just spent the last couple of hours reading through it from top to bottom and its given me the confidence to believe its something I could do too. Your attention to detail is outstanding. The windows for example, just amazing! You must be incredibly proud of your efforts."

  • "Thank you for giving me the courage to take on a job that I was considering letting someone charge me thousands for! Your site is brilliant, good luck with the rest of the build."

  • "I have been scouring the Internet trying to find a website to help me understand each stage of building an extension. Thankfully I came across your website."

  • "I'm in the middle of a self build extension and have just stumbled on your site. I'd just like to say I am finding it very useful and wish I'd found it sooner."

  • "Thanks for a truly professional web site i am about to start an extension to my home and found the information incredibly useful , I've had ridiculous quotes to have a builder do the work for me and have decided to take the plunge and do it myself"

  • "I'm just about to start a garage conversion project and I found your website and already it's been a massive help… just with the building regs and where to start. Reading what you've done and been through has made me feel loads more confident and I've no doubt I'll be back to check on things."

  • "I have just found your site for your extension a few years ago and I must thank you for the excellent pictures and detail you have provided. It has really inspired me to build my own porch following a ridiculously high quote from a local builder."

  • "Just wanted to say thank you for sharing your photos and information on your build I found your page on  myhouseextension.com   when I was looking for advice on how to build a roof for my summer house.  Great pictures that gave me all the information I needed."

  • "Thanks for a really good site. I was looking for info on building a garage but now i have discovered your site i feel i can build a house!. The photos are really important .keep up the good work "

  • "Absolutely brilliant. I am planning a build onto the back of our house, essentially a playroom with lots of roof lights etc. etc., and with enough scope to allow me to turn it into a bit of a den in years to come ( Please God ). I have learned so much in the last hour I will be back to your site. Well done you. "

  • "Brilliant website! I spent nearly 4 hours reading your website and looking into the details. It's like a suspense book that I couldn't put down until the very end. I have done a considerable amount of DIY myself and I surely do admire your work. More power to you and your endeavours!"

  • "What a great resource. I've just self build an extension and am not a builder. However I did sub our electrics, plastering and structural engineering calculations. I should have taken more pictures. Ready to fit kitchen now, 42 months after taking a space to the lawn."

  • "I hope you don't mind me emailing you but iv just finished reading your step by step guide to your DIY extension build all i can say is "THANKS " the wife and i wanted an extension built but just didn't  think the budget could  stretch that far . I have been put off by attempting it myself even though i feel i am a more than competent DIYer  but now after reading your article i feel very very confident than i can do it (even if it is with a little bit of help from my friends) .I spent hours trawling through the websites looking for help and i found help in your journal"

  • "Your website is a great tool for the "layperson", to enable them to appreciate the fundamental needs and understanding of such a project. Even though I consider myself "competent" - it was the final push that I needed to go with the courage of my convictions.
