How To Plan A Home Extension

Whatever extension type you choose, there are critical steps to extend your home, often determined by the work’s size to be done. Following these 12 steps will give you a hassle-free extension on your property. This 12 step process assumes you already reached a contractor, your needs and requirement have been considered, and the price has been quoted for you.

These steps show you how to plan your extension and know what stage your project is in at every phase.

1. Planning

This is often an essential part of your project and usually involves getting an architect to make a drawing plan. When you need to obtain planning permission, you need to apply for it at the Local Building Authority (alternatively, you can apply online) before the project commences. Once the plans have been approved and a contractor secured, the site needs to be prepared. This prepping will include clearing out the extension space, delivering the materials to the site and other minor activities.

2. Groundworks

The foundation will be dug, and reinforcements will be installed. Pipework and drainage will be laid as necessary, and the concrete for the footing will be poured and levelled. You can expect one or two control visit during this period.

3. Superstructure

This is all about securing the structure, ensuring it is sound and damp-resistant. The brickwork will be completed to the level of the damp-proof, insulation will be fitted at this point, and the flooring poured. You can expect another building control inspection at this point.

4. External walls

Up next is completing the external block and brickwork, including tying the new walls to the old ones. The frames and lintels for the windows and doors will be fitted as the brickwork progresses. Before the wall is completed, the cavity wall insulation will be done.

5. Internal wall

The internal walls and divisions will follow next.

6. Roof structure

The structure to support the roof will be built by the carpenters. The roof window or dormer frame will be completed (if there are any roof windows). Following the building of the roof structure, the coverings for the roof is installed.

7. Windows and doors

Any external rendering will be completed at the same time as the windows and doors are fitted. Drainpipes and guttering will also be completed during this time.

8. First fix

Once the extension is weatherproof, the first fix will take place. This is the electric, plumbing, and carpentry that underpins the extension.

9. Breakthrough

The wall separating the extension from the rest of the house will be pulled down and steel girders installed where necessary. Usually, there is another building control inspection at this stage

10. Plastering

Internal insulation is up next, and the plasterboard will go up, while the walls will be skimmed, ready for decorating.

11. Second fix

The second fix of electrics and plumbing is next. Sockets and switches will be fitted as well as lights. Taps and plumbing connections will also be completed. Flooring will be laid. When this is accomplished, any kitchen work will be fitted. Another building inspection follows

12. Snagging

Once the project is completed, time is spent in the extension to ensure that everything is in perfect order and the problems found are solved. Check for heating problems, leaks, poorly-hung doors and finishes.
