Study 1 is a four bedroom home from nothing but an empty piece of land. We designed, built, and even filled the swimming pool up.
Firstly we marked out the ground area for the 27 pads. Seems excessive but it’s not the land here is soft and it was favourable over piles. We did not want to pile and leave other homes with damage from the machine shunting the piles hard each time.
Once we marked out the pads we had the digger round to dig out 27 holes neatly and square. The holes are 1.5m2. This may seem excessive but we were told by owner that he may want to expand to a second level and we should put all structural integrity in place so that the retrospective install would not be hindered or more costly.
Once marked up rebar pads and columns are then tied and fixed into position. This process is a little time consuming because we must get everything 100% accurate right here, there are no second chances. Concrete is then poured into the pads and a few courses of breeze blocks are added to bring the level up.
Once set the breeze block casing is poured with concrete to ground level and the earth back filled in the holes. At this point we are now capable of seeing whats going on again. Things were a little disorganised prior because we had so many holes to dig out.
At this stage we can now think about running ring beams at ground level to create the strength of our clients home. Typically ring beams will be 40cm by 20cm. This is more than enough to support a 10cm thick concrete slab floor. The weight is also not too much that it may cause subsidence issues in the future. One tricky part that required extra depth and rebar was the parking area. Because it’s 6m wide we had to significantly reinforce this area.
Once all rebar tied we need to shutter and get ready for the concrete pour. The shuttering is typically wood or metal. We prefer metal as it’s quicker, and neater, but the client wished to re-use smaller amount of wood throughout the project to save. This worked well because once we turning the planks into shuttering the they are good for many pours. We used each plank for around ten pours which is excellent for the environment. This works out to around a third of the overall cost of hiring metal. The planks are still useable now if the client so wished to make another smaller holiday house somewhere (which is what they are doing now).
The columns are then shuttered and poured after the beams and then the slabs are all poured in one go. We running electrical and plumbing at this point to ensure all cabling and pipes can be hidden. The roof was concrete slab so we had to create further ring beams and cast a second level. Normally this is not necessary in a single level home however the client wished to have the option for level two. Wise because he is already doing so.
Bricks are then used as fill, they carry no structural benefit. We used two layers to create a cavity which will save the homeowner for the lifetime he is at the property. The bricks are rendered and squared up.
From here it is finishing work so I will leave some pictures do you can see where the project wen’t from here. We installed the swimming pool, central heating system, and wall for security.
