Stages of House Extensions


As a home extension’s impact on family life varies from household to household, the first question that arises in every homeowner’s mind is how long the project will take. How long it takes to build an extension depends on the size of the extension and the complexity of its design. It takes approximately three to four months to construct a simple single-storey rear extension of around 100 square metres in size, but it takes six months if this work involves the construction of a large or double-height extension that requires planning permission.

Design & Planning

Initial stage :

When you first meet with one of the talented design consultants, you will discuss your ideas and goals. You can ask any questions that come to mind and the consultant will offer suggestions for the best possible solution.

Designing concepts:

A design consultant will begin work on your house extension. They will keep you updated on their progress, and we will work together to create a plan that meets your needs.

Revision work and finalizing the design:

At this stage, the company is ready to move on to a final design for your home extension. The company will work together with you to accommodate any last-minute changes you may have, and when all is settled, the company will have a plan to submit to planning authorities.

Let’s work on the Contract

After the design has been finalized, you can contact the house extension company. Before starting the project you need to sign a contract with a company to formalise the agreement. It is essential for you to write all aspects of the project.


At this stage, the company ensures that the home extension work satisfies all regulations. You need to complete all documentation if required and avoid any unnecessary delays.

Construction work

Site preparation

Depending on the layout of your extension, it may take one week to prepare and assess your property before the building work can start. In this stage, company ensures that there will be no restrictions in the building processing and setting out of your extension areas.


After completing the framework of a house, the company adds the doors and windows. These additions are called “lockups” because they secure the structure.

The project completion

The final inspection is the last step before receiving the building permit. After completing all the finishing work and getting the final certificate, you will receive your permit.
