How Do I Design A Single-Storey Extension?

Choose Doors And Windows:

Choose the dimensions, style, and position of your doors and windows supported by the style of architecture of your extension. Don’t ignore the choice to usher in many lights from above, like with roof lights.

Flooring At The Same Level:

When you are beginning the ground levels for your extension, you ought to work backward from the finished level of the ground within the existing property to form sure that the 2 are going to be identical once they’re linked together.

When you’re remodeling, instead of extending, any differences within the floor level be corrected by build-up, often by employing a quick-settling silicon floor screed. If you can’t easily get an equivalent floor level, then it’s better to make a full step. A little difference can easily become a visit hazard, so create a step.

Use Finishes To Match The Existing House:

In some extensions, you’ll want to make an extension that appears seamless, so choose equivalent windows and other details of the remainder of the house.
