Permitted Development Porch Extensions

A porch provides you with an excellent welcoming area to your home. At, your personal designer will create your perfect porch!

​Permitted Development allows home owners to create a porch of up to 3m , which allows the perfect space to create an area for a boot room, coat room or simply the space you require at the front of your property. The size of porch is set by the Government through their Permitted Development Technical Guidance and we have specialised into optimising these regulations to deliver your perfect porch. And even if we discover that your desired conversion may exceed the regulations, there is nowhere better to go as we have unparalleled planning knowledge in small extensions.

At the Permitted Development Specialists:

We undertake a full measured survey of your existing house to enable us to plan your home reliably and cost effectively. We produce as existing drawings of your property which are required in your Lawful Development Certificate.

Your personal designer will undertake a detailed design brief with you where we will discover exactly what you are looking to achieve from your porch extension. They will design a concept from your brief to create bespoke architectural drawings tailored for you to deliver your perfect porch.

We provide you with the highest quality floor plans, elevations, and 3D views as seen in our videos. These rendered images will give you a full understanding of materials and finishes to the outside of your new porch, whether its front door style, window casement or material finish. You'll be able to see exactly what it looks like in real life before it is built!

Your personal designer will then tailor the concept to create your perfect design! We understand that this process is difficult and decisions are hard, however, your personal designer will always be there to aid you and be able to draw recommendations from their architectural and local planning experience. 


Once the design has been achieved, we will obtain a Lawful Development Certificate, or if it is required, planning permission. You are now ready to build!


Legally, you must ensure that your project complies with building regulations which is a statutory requirement.

Our building regulation and structural drawings cover everything from the foundations all the way up to fire regulations, thermal efficiency, and even sound insulation. 

We have vetted chartered structural engineers, building regulation specialists, party wall surveyors, drainage experts, land surveyors, and all other potential third party specialists that could be required in the signing off of your project.

This process will leave you in the best possible position going into the construction phase, providing your builder and your local authority's building inspector with everything they require. 

We hope you are as excited to start your project today as we are! Please fill out our Contact Us form below so we can start your project as soon as possible. Or feel free to call us where you can speak to one of our specialists for any information you require.
