May 2015,
Wow, its been a pretty long time since I had any updates. As I mentioned the last time I've been building a garage as my boss wants his garage back. The good thing is he hasn't really been in too much of a rush to get me out. As with the van I've only been able to do the garage on the weekends and some nights after work if im not too busy, too tired, crappy weather, planets all a lined, blue moons etc... Its actually taken quite a bit longer than I hoped but I am getting there. I'm also too cheap to pay someone else to do things for me.
So, to recap from my last post il add what I wrote before.
So my new project that I'm going to have to rush though is a double garage. Scotland's rules regarding a garage without having to get planning permission are actually quite relaxed. Here are those rules.
(1) The provision within the curtilage of a dwellinghouse of a building for any purpose incidental to the enjoyment of that dwellinghouse or the alteration, maintenance or improvement of such a building.
(2) Development is not permitted by this class if-
(a) it consists of a dwelling;
(b) any part of the development would be forward of a wall forming part of the principal elevation or side elevation where that elevation fronts a road;
(c) the height of the eaves would exceed 3 metres;
(d) any part of the development would exceed 4 metres in height;
(e) any part of the development within 1 metre of the boundary of the curtilage of the dwellinghouse would exceed 2.5 metres in height;
(f) as a result of the development the area of ground covered by development within the front or rear curtilage of the dwellinghouse (excluding the original dwellinghouse and any hard surface or deck) would exceed 50% of the area of the front or rear curtilage respectively (excluding the ground area of the original dwellinghouse and any hard surface or deck); or
(g) in the case of land in a conservation area or within the curtilage of a listed building, the resulting building would have a footprint exceeding 4 square metres.
The only part of that which has been my biggest challenge is the 2.5 metres max within 1 metre of the boundary, due to my garden being about 6 metres wide and the garage being 5 metres wide. Ive spent a lot of time drawing and measuring so I don't need written permission (I,e a huge amount of money and time).
This is the garden when I moved in.
Since then I've had to lift all the stone chips and mark out my dimensions for the monolithic slab I will be pouring in. Underneath the blue tarp I have about 40 concrete sectional panels I got for a steal second-hand.
The outer edges of the slab will be 300 x 300 then the centre will be 150mm thick, of course I will also have rebar and mesh in there too. Gives me a good indication size, really happy to actually start my dream of my very own double garage :).
Which brings me to today. The trenches are dug and I'm now skimming the top layer for the centre of the slab. A few people have already asked me why I'm not just hiring a digger and skip to do it all but to be honest I'm absolutely skint. I managed to get a small loan for the material but if I can save myself money by digging and disposing of the clay/soil in a trailer at the local tip I will. (even if that means roping in my poor brother to lend a hand, cheers bro)
I'm hoping next week will be the last weekend of digging. And I can get the rebar in and concrete poured maybe around mid February, we'll see........
-----------------------------------------------------------------------
Ok, so I did manage to skim the top layer off but I stumbled across a bit of bad luck. The weather took a really bad change for the worse and it chucked down with rain for a solid week a few days after all the digging. The ground was complete mush, really sticky clay and it was soaked all the way through. I had hoped that it wouldn't rain as the clay was quite firm and I hoped to just pour directly over that. In a very vain attempt to do something I even covered it with tarp to see if a couple of weeks would help to dry out at least the centre.
But it was no use. Once I took the tarp off it was just as bad. I felt really quite upset and a bit stressed out at this so I looked up what to do on google. So to remedy the situation I ordered 3 tons of hardcore to be delivered. To make space for all the hardcore though I had to go down another 150mm which my dad kindly helped me wit, thanks dad. Then I think it was the next day the hardcore was delivered. I had learnt my lesson not to have too much time between vital jobs.
My dad came back along that day and helped me to spread it out and I hired a whacker plate from the local hire shop and after a few hours I had a really good strong, firm base to pour on. I bought a few lengths of 6x2 to use as shuttering with some 2x2 stakes and took my time laying it all out.
Once I was happy with the shuttering I ordered the concrete and took a long weekend off so I could prepare the damp proof membrane and rebar to go down the day before it arrived so I wouldn't get puddles if it rained. I bought the rebar a little while before so for speed I had already welded these into long cube shapes so all I had to do was place it in, no need for tying them together with wire. The rebar is 16mm thick with 8mm mesh, its probably a bit more heavy duty than it needed to be but for the sake of ยฃ30 - ยฃ40 I thought id do it strong.
Then the DMP went down. I also ran a small length of water pipe so I can run an electric cable through it when I'm finished. Also, to save a bit cash on mesh supports I just broke a few slabs into small bits which raised it to about 60 mm, the thickness of the foundation in the centre is around 120-140mm
All ready !
I had ordered a mix of C25 concrete from a company that done a pretty good price. My brother and Dad came over to help out with the spreading. None of us had ever done this kind of thing so we may have made a few mistakes but the end product is pretty good. I had looked up a few videos on yotube about concrete pouring but I couldn't find one that covered pretty much all of the pour without being either sped up too fast or just a lot of editing to make the video short. I decided to record a full hours worth of video and I put it on youtube if anyone else is interested in the process. Here's the link to that video if anyone's interested.

It was pretty hard going, shovelling, raking, scooping really took its toll on us. Trying to do all of these things as quick as we could and keeping a level head to know what to do next was difficult, but we managed to get all the concrete poured in in about 45-50 mins so I didn't have to pay any extra to the driver and once he left I just had the skimming to do. I hired a long float from the same place as the whacker plate to get a more professional looking finish. At the end of the day I was left with a very expensive piece of concrete but I was really happy as it meant no more muddy shoes and clothes !
๐ .
The next few days I was pretty apprehensive, checking on it all the time to make sure there was no cracks forming and that it was setting well. After a couple of weeks I too all the shuttering off and it was still intact, phew!
I had a few other things going on at the time so I left it another couple of weeks. I then ordered 60 concrete blocks to be delivered. The garage panels I bought second hand are only 2 metres tall, so to get a bit of extra height I wanted to build a small one row of blocks around to put the panels on top of. This is also the first time I've done any mortar/block work. My big book of DIY came in handy again for this.
The only real bother about this is the fact I don't know 100% to the millimetre where the panels will end so I decided to build the front half of the garage first, then when I work back I can put the last few blocks in place when I know where the last panel will land.
Once the blocks I needed were in place my brother came along and helped me put up the first corner. I managed to get 2 double glazed windows for free from my work so for that area I built a small wall up with blocks.
Then when I was happy with the little wall I welded up a door frame.
Few more panels put up. The panels join to each other with 4 M8 bolts. I managed to tap into the door frame so there attached to that also.
I had also been making up my roof trusses after work during this time too. They are scissor trusses made from 50x3 angle and 50x50 box. When designing them I wanted all the joints to be extra strong so they overlap in some areas and braced in others. My boss was nice enough to let me use the workshop for this.
The beauty of them is I needed 14 halfs to make 7 whole ones but 11 of them are identical so I only needed to make one jig.
My dad and brother came back along to help me set the first end truss up plus put a few more panels up. Then when they left I put the windows in.
Which brings me upto how it is today. Both my brothers were here yesterday and helped me get 2 of the trusses up into position and a few more panels up.
To attach the trusses I bolted down a length of 50x5 angle to the top of the panels. Worked out the centres for them, then cut out a 55mm wide slot to drop them in place. Once I was happy with there position I welded them down.
I wish I never took so long to do this update as I've forgotten half the details I was going to put in. I did actually think id have it done by now but so much is going on I'm strapped for time. I got a promotion at work so I'm now th eworkshop foreman which has been pretty good plus it means a little more per hour, yippee.
Now I need to go outside and mortar the last of the bricks as I know where they are going to be so I can get the rest of the panels up and secured.
I have also managed to buy insulation for the roof, 50mm thick foil backed foam as I'm making it a warm roof. I got them from gumtree from someone that bought some for his conservatory then changed his mind so there still brand new. I also managed to get some second hand box profile roof sheets, 0.7mm thick. That was a bargain! ยฃ80 for the whole roof. They had been in a firedamaged building. They still have all there integrity, just a little bit of soot on the underside.
My biggest concern are the actual garage panels themselves. 80% of them are fine but the rest do have some fine cracks in them, I'm not really sure exactly what il do with them. I thought about some kind of crack injection repair but il have to look into that. In hindsight, I think I should have just built the whole thing out of concrete blocks. Too late for now, il need to see how it goes.
