House Extension

Foundation

Setting out the home extension.

One of the most critical stage of the build is setting out the foundation. If these are not perfect the building that sits on top of these may not be the right size, in line with existing house or be unsafe. On larger project a surveyor will set out the site.

Pouring of concrete into trench foundation when the site setting out is completed and fully marked out. The excavation can begin. A digger dig out a trench usually 1 meter deep (depending on specification in your structural drawings) and concrete is poured into the trench. 

Building blockwork

Forming a solid base for superstructure.
After curing of the concrete, block wall is built up to the damp proof course (DPC), this is a layer of a plastic material that stop water rising up through brickwork.

Walls and scaffolding.
Construction of superstructure and temporary services.
The walls can now be built and scaffolding need to be erected in order for bricklayers to be able to work safely and effectively. 

 Open plan formation and removal of existing structure. Carrier walls installation and restructuring.
 Open plan formation and restructuring of the existing building in order to create open plan living area. This is a critical part of the build where you would connect the existing with new and for an open plan living space.

Waterproofing

Waterproof of the home extension or the new build home.
Adding a roof on top of the house.
Once you have the windows installed and the roof completed the house is than sealed and watertight. This means that the work can begin internally and various trades can start the work from inside the house. At this point the progress speeds up of the overall build.

First and Second Fix

Carpentry, electrical and plumbing.
Building is waterproof and sealed the internal work will begin. Starting with electrical first fix and piping done by plumber, carpentry work such as stud walls, and room formation or staircase, door installations. After walls are plastered plumber, electrician and carpenter would come back to finish off the and complete the work.
