Resources

Discounts, tools, materials and viewing

Welcome to this resources page, a curated this list of tools, materials and suppliers I recommend to succeed in building your garden room. I have used nearly every one of these resources with the exception of a few tools where the exact tool I used is no longer available. I’ll put an * next to any that I haven’t purchased myself.

An important disclosure – some of the links on this page are affiliate links, which means that if you choose to make a purchase, I may earn a small commission. The commission comes at no extra cost to you of course.

Discounts

Who doesn’t love a discount! I reached out to these companies after using their products on my garden room  to see if they would offer a discount to viewers and I think it’s great they saw the opportunity in what is rather a small YouTube channel! If you use them, go show your appreciation in a review (but best not mention you got a discount). I’m working on getting some other discounts for you soon!

With great reviews, excellent training videos, a simple to use calculator and next day delivery across the UK, this is a great buying experience from a family run company.

Just input your actual flat roof dimensions into their online calculator along with the trims (edge, gutter etc) you want and it automatically works out the required EPDM overlap, the number of each type of trim, joint and corners trims, nails and glue. Smart!

You can then select your trim colours, upgrade to 1.5mm thickness EPDM (I used 1.2mm and that’s been fine)and get the installation kit (rollers etc) if you need it.

The EPDM comes with a 20 year guarantee but only if the roof is installed by professionals but it’s a good testament to their confidence in the product. For those building to b-regs standards, here’s the Classic Bond certificate.

Discount: to get the code, either email me at hello@alidymock.com or use the contact form.

With a wide range of corded power tools, Evolution is a great brand for those getting started in DIY but want better quality than the Screwfix and B&Q own brand tools.

Use this link and code ‘ALIDYMOCK5‘ for 5% off any product. It may be worth checking Amazon too to compare prices.

Evolution were kind enough to give me a mitre and circular saw to try out and I give some brief opinions on the former about half-way through this video.

 Not garden room related,  but I made a video on staining, oiling and installing an eBay bought side gate. The seller reached out and offered a 10% discount to viewers going direct. 

Andy runs his business solo from his workshop in Lincolnshire, sourcing all the redwood pine from his local timber merchant with delivery in just a few days. He can do bespoke sizes to fit any gap. Give him a call on 01522 697793 or email graysgates@gmail.com and mention this website for the discount.

Span Tables

I’m not allowed to give out the span tables shown in the videos so instead I’ve made my own more simplified version with some extra explanations, free to download.

I had some trouble with the zip file so instead I’ve uploaded it as a PDF which opens up in a new window which might be a good thing as you can access it easily on the go from a mobile. You can then download the PDF from that window if you want your own copy.

SketchUp plans

The plans I made on Sketchup have been asked for a number of times so here they are! First you’ll need to download SketchUp, it’s totally free to use and there are plenty of YouTube tutorial videos out there. You can get the program here.

As mentioned in Part 3, these are only rough plans, the floor joists aren’t as I built them and the roof is flat rather than sloping, but hey, they helped me visualise my build, calculate building materials and better understand framing. Anyway they’re free!
