Whether you are looking to create additional space for your home or add a bit of value, allow Design & Development Associates to guide you through the house extension process in a simple and hassle-free manner.
We offer a free consultation to fully understand your needs and provide expertise on the way forwards.
Once our terms have been agreed, we undertake a full house measured survey and work with you to bring the project to life.
Once the perfect design has been reached, we will submit the design to the Local Authority and gain the necessary consents. Our services includes the management of the application as standard.
Once approved, we can explain the Building Regulation process and liaise with Structural Engineers and Building Control as necessary to ensure a seamless project start.
With increased stamp duty and rising property values, house extensions are a great way to add the much needed additional space to your home without the stress of moving. Most extensions can be constructed externally, with the break through only being undertaken in the latter stages of the project, meaning that you can live at home while the works are being undertaken.
Recently relaxation in planning rules means many proposals fall under permitted development, so planning permission is not required. If you are considering a house extension, or would like to see if this can add much needed space to your home, contact us for an honest and impartial appraisal.

Home extension costs vary depending on size, design complexity and specification. As a guide, current build costs are often around £3,000 + VAT per square metre. Once plans are prepared, we can help obtain build estimates and adjust the design if needed.
Our fees start from £995 + VAT for a full design pack for a simple application, including measured survey, design process, submission and management. We provide a bespoke fixed-fee quotation after your free consultation.
After instruction, we arrange a property survey, which usually takes around 1.5 hours. We then aim to issue initial design concepts within approximately 10–12 working days. Once approved, we can submit to the council or help obtain build estimates.
Some extensions can be completed under permitted development, while others require planning permission. We assess this during your initial consultation and advise on the best route for your project.
A householder planning application currently costs £639, paid directly to the council. A Lawful Development Certificate costs £365. Once validated, most applications take around 8 weeks, although this can vary depending on council workload.
No. We provide a single point of contact throughout the design stage, planning process and building regulations preparation, helping make the pre-construction stage as straightforward as possible.
