Why Choose APD Interiors for your Extension?

At APD Interiors we have many years’ experience of designing and building people’s homes, by listening and implementing people’s design requirements and aspirations.

Our extension projects are all different and we don’t deliver an in house style. No project is ever the same, we believe in creating a home to suit you and your family, and to your budget.

As we progress through your extension project we have a great team of associate consultants we work with including quantity surveyors, structural engineers and building inspectors. All our extensions fully comply with the latest building regulations and come with many energy saving features as standard.

Your Space

Recent figures from the Royal Institute of Chartered Surveyors show that while the housing stock is growing there are fewer houses being bought and sold. People therefore are staying in their homes longer and more people are extending.

When we plan your extension at APD Interiors our architectural and interior design teams work together to ensure we deliver you the space that your require, delivering a new home for you to enjoy from the day you move in.


Following initial contact one of our team will visit you for an design consultation at your home. We will then prepare a fee proposal for your project detailing fees and the process. After accepting the proposal a very thorough survey of the property will be done and architectural plans drawn up.

Our initial design ideas will be developed and from these the initial plans and a preliminary design will be put together. All aspects of the design will be covered including structural design, lighting and heating, fittings and furniture. We even handle all the planning permission aspects with the local council and if your property is listed, the listed building consent.

Once you have gained the required permissions and agreed the specification our build team will now take over and deliver you your extension.
