It’s been a long time in the making but my garage/workshop is finally built! We started this project in September 2016 after receiving planning permission for planning documents that I drew up and submitted myself. It was only supposed to take 4-weeks but alas….the builders tried to scam me!

Long story short, builders that I thought looked decent enough turned out to be liars and just general scum. Alarm bells started ringing when they laid a thin wafer of a concrete base without any reinforcement, then they stopped turning up with excuses about family troubles, followed by a confession of sorts about how they were actually planning to build the garage which was nothing like we agreed with the structural engineer and was downright unsafe! Have since spent the last 9 months recovering a small sum of money from them (my deposit and a partial payment towards materials that I never received!) with the help of trading standards. I feel like I dodged a bullet but it’s still been a long stressful time! New builders were epic and have certainly restored my faith in tradesmen in general.

Anyway, onto the photos! The general idea was to remove the old concrete prefab garage next to the house, turn that into a driveway behind solid gates and build a new larger garage into the back garden. The back garden is sloped so the walls of the new garage needed to be substantial retaining walls for the surrounding earth. Steps needed moving and we also removed the bottom tier to give a bigger patio area.

A couple of shots before we started work.





And then the scum builders started demolishing the old concrete prefab garage and digging out the earth to make way for the new garage. At this point, everything looked pretty kosher.





Alarm bells! I got home from work one day to find they’d laid membrane down and then just poured 3” of concrete in without any rebar support, no steel for the walls to be built on, the worst looking shuttering I’ve ever seen (yes, that is part of concrete prefab garage wall!) and no drainage. I called them up on it and was told “Fibres in the concrete add strength, you don’t need rebar”.





Finally had a confession from them stating they were going to use a single skin of block with cement poured inside. No rebar and nothing to anchor it to the concrete. I told them not to bother coming back and to refund my money. It was getting towards the end of the year and the weather was turning so we decided to put up scaffolding to ensure nothing collapses with the frost over winter. It’s a bad time to build anything and no builders were available to start the job on short notice.



At the beginning of 2017, the frost did start to do damage. Clay behind the membrane had collapsed and was bulging while a bit without membrane just fell out. Unfortunately, there wasn’t too much we could do as the new builders weren’t available yet so had to wait it out.




Finally, new builders started and everything began to look up! Old concrete chopped out, proper shuttering built, 30” of concrete poured with two layers of mesh rebar and rebar bent to 90 degrees to anchor the walls to. Perforated land drain ran all the around base of the garage to help drain water away from the walls.




Walls started going up. Double skin wall tied together with steel and the cavity filled with mesh rebar and concrete. Any part of the external wall that would be visible is simply built with face brick to match the house. Patio wall also started and build double thickness without a cavity.









Roof trusses in place with felt and tiles. Drainpipe to match the house also added.





Steps to the side built. Finally have access to the top of my garden again!




Finishing touches! Side door fitted and electric roller shutter garage door fitted. Armoured power and network cable run from the house, under the steps and into the garage as well as a new consumer unit and connection.







I've still got the rest of the patio and upper garden to finish. Also planning to plasterboard and paint inside the garage to make it nice and bright.

Any suggestions on bright LED lighting?
 
Turned out great in the end. Did they have to do any waterproofing on the walls that are backfilled with clay? Or is it just the black plastic sheet?
 
My god that pre-fab view in the second picture, what an eyesore ! The pain was surely worth it to be shot of that. What did this all cost you in the end ?
 
nice looks amazing
you must be very proud of that, especially with the difficulties you had at the beginning of the job.
 
That is the size of garage I could do with - it's a bit wider than mine. Also why did I have a up and over door and not a roller ??? Duh!!

Tell me - what is there to stop any water seeping into the concrete blocks and through concrete and into inner concrete blocks - If there isn't anything won't blocks act like a sponge and suck water in. - For your sake I hope not - such a nice well built garage.
 
Thanks for the comments guys. It was a horrible start but has turned out well in the end :)

Looks good, personally I'd have done a living grass roof. :)
Haha, the thought crossed my mind! as well as a rear mezzanine level inside so I could wheel the lawn mower into it straight from the grass on the upper garden.

The prefab was hideous. It's amazing how much nicer things felt when it was gone, not to mention all the extra light in the kitchen from the side door and window. Initial quotes were between 16-18K but it's probably a bit closer to 20K all in after a few alterations that were made.

I think the US are reserving a bunker buster in case you ever turn to ISIS ;)

Looks sweet, at leeast you wont have any issues getting on the roof if needed for access :)
The roof is prime solar panel real estate :)

I did consider up and over but I wanted to maximise space in case I ever built light storage in the roof. An up and over may have got in the way of that.
There is a membrane behind the wall to try and hold back some of the damp, plus the gap between the surrounding earth and wall has been backfilled with pea gravel and then top soil above the perforated gutter that runs around the edge of the base. The idea is to encourage any rain water to find it's way down to the gutter before it reaches the wall. I'm not sure how true this is, but I've been told by a couple of people that the heavy clay that my garden is made up of should remain dryer than other soils because it's much harder for rain water to penetrate (albiet, it stays wetter for longer once it get's wet). When it was being dug out, it was coming out in solid dry chunks like rock with lots of coloured layers that have built up over the years. I've also been told that it'll never get below freezing temperature and will tend to stay a couple of degrees above?
