Various styles of extensions to suit whatever need you may have for your project!

Here at PDE (Pre Designed Extensions), we are committed to defying the conventional beliefs that restrict possibilities in architectural projects. We specialise in obtaining planning permissions and permitted development certificates by providing Pre Designed Extensions tailored to a large number of Semi Detached and Terrace properties. 

We aim to modernise the architectural process by offering a flexible, subscription-based service. For a monthly fee, you’ll gain instant access to hundreds of pre-designed extensions tailored to various housing styles. You can download these designs without watermarks, customise them to your needs, and submit them for planning approval with ease. Subscriptions can be cancelled at any time, offering ultimate flexibility.

With a vast design catalogue at your fingertips for a fraction of the cost of traditional architects, our service offers incredible value. Whether you need ready-to-use drawings or want to customise a design, PDE gives you the flexibility to bring your vision to life without the hefty price tag.
