A house extension can be one of the best ways to create more space without moving home. Whether you are planning a larger kitchen, an open-plan living area, an extra bedroom or a complete ground-floor redesign, careful planning at the beginning can make a big difference to the final result.
At Loft & Extension Experts, we work on house extensions across Surrey and South West London, including Walton-on-Thames, Weybridge, Esher, Cobham, Molesey, Surbiton and Kingston upon Thames.
Choosing the Right Type of Extension
The right extension depends on your property, available space and how you want to use your home.
Common options include:
Rear extensions – ideal for enlarging kitchens and living areas.
Side extensions – useful for creating additional rooms or increasing ground-floor space.
Wraparound extensions – combine side and rear extensions to create a much larger living area.
Double-storey extensions – can add valuable space on both the ground and first floor.
A good design should work with the existing property and improve both the layout and the appearance of the home.
Planning Permission and Permitted Development
Some house extensions may be possible under permitted development rights, while others require planning permission.
This depends on several factors, including the size of the extension, the position of the property and whether there are any local restrictions.
Before starting work, it is important to check the planning requirements for your individual property.
Structural Work
Most extensions involve structural work.
This can include:
new foundations
structural steel beams
supporting walls or piers
roof construction
openings into the existing house
Structural drawings are normally required before this work begins.
Drainage and Manholes
Drainage is an important part of many extension projects.
Existing drains, manholes and soil pipes can affect the position and depth of the new foundations. In some cases, approval may also be required if building close to or over a public sewer.
A drainage survey can help identify any potential problems before construction starts.
Building Control
Building Control inspections are required during the construction process to make sure the work meets current Building Regulations.
Typical inspections may include:
foundations
drainage
structural work
insulation
roof construction
final completion
How Long Does a House Extension Take?
The timescale depends on the size and complexity of the project.
A simple extension will usually take less time than a larger project involving structural alterations, drainage changes, new heating systems, kitchens and complete internal refurbishment.
Good planning before construction begins can help reduce delays.
Choosing the Right Builder
When choosing a builder, it is important to look at more than just the price.
You should consider:
previous extension projects
experience with structural work
knowledge of local Building Control requirements
clear and detailed quotations
communication throughout the project
reviews from previous customers
A detailed quotation should clearly explain what is included and excluded.
Every extension project is different, which is why good preparation is so important. Before construction begins, drawings, structural details, drainage and access should all be considered carefully. This helps avoid unexpected problems once work is underway. At Loft & Extension Experts, we believe clear communication and a detailed quotation are essential from the beginning, so homeowners understand the scope of the work and what is included in their project.
