Building an extension

Putting hands to work creates an exhalation experience when it all comes to plan. learning is good knowing the reasons behind your actions.There are a lot of different form of college or apprentice work you can acquire if you really want to beat your level of understanding on the project. Books are also good as most building regulations do change.

You might have a extension at the back of your house that no longer interest you for reasons being it may be shoddy work, leaking, or an upgrade from plastic to brick. With most extension projects exceeding over 3 metres you will need to acquire planing permission from your local council. So it is worth bearing that in mind.

To keep things under the wraps, stick to a tight budget like a monster and be prepared to put your project down on a schedule list along with materials. Shift the original safely by removing electrical wiring, gas and water pipes. Bear in mind that the extension will have old bits that can be recyclable such as plywood and parts of old Window that can be used for, I.E. use of a partition for the use of a kitchen sink whilst work is in progress.


Check that the original extension walls is not lined with asbestos. If' you have kids and there's asbestos lining, this would be of concerns as to calling a certified none license asbestos company to remove it. Ring around for quotes to remove the stuff as specialist will charge a fee and will dismantle it and remove it safely.

Remove all the interiors to a designated spot then remove the front as to block off the opening from the elements before taking down the structure starting from the roof. Leave most of the timber framed uprights so you can work on the roof safely.

Used a steel wreaking/crow bar to prise and roll up any felt with help of another person. This is probably thick and covered in bitumen tar and is usually heavy weighed. Underneath that there should be some boards which also can be prised up. Make sure of where you trod as some floorboards/ply or chip boards may be rotten. If the wood is still good you can use it to make a tool box for a nearby storage. When the boards are taken up tread carefully on the ceiling joist and poked down the Plaster board ceiling from above and dismantle the uprights from the ground.

You will need to excavate the foundations trench cavity of 1 metre deep/on in approx 1 feet in line with building footing with the width of 2 feet wide. You will also need to higher a digger to excavate this and excavate it leaving clear ends from the side to place your brick work. Once the cavity is excavated, usually if the extension exceeds the regulated extension of 3 metres you will need to call the housing inspector to do his first viewing.

If all is clear go ahead and hammer some 2 and half feet stakes the bottom of the trench leaving the tops with a spirit levelled 2 feet above the cavity floor level for levelling the concrete once it is poured. Pour 2 metres thick concrete into the cavity levelling it with a wood baton to the hight of the wooden stake markers.

At this stage it may be worth getting some tarpling to cover your work area or you may find you have to pump out water before you start the brick work. Start building the wall at 100 mm (4 inches) cavity starting with engineering bricks, inserting brick ties at 6 in every square metre. Tie the brick between the wall cavity
and at the wall to the building screw ties to the wall.

Build cavity wall above ground level three brick high. Screed concrete is then poured up to ground level and roll of D.P.C is place on top of the wall and all so tied into the existing building by means of removing the mortar from the brick and ceiling in the D.P.C with mastic silicon.

This would have brought you to the next stage where the building inspector does his check and with the all clear you can move on to the next stage. when you have planed the opening for the doorway and window you can make wooden templates to build up to for quick checking for squareness. shop around and choose the type of bricks you would like to see you extension built out of and build starting from the corners checking your spirit level as you go. At the top of the door and window place a steel lentil

 on a bed of mortar and continue building.


 when you reach the top you decide if it's a pitch or a flat roof you want.
