Kitchen Extensions... Do they need planning permission?

Often our customers are having a new kitchen because they have moved house and are having renovation work done, or they are extending their own home.

With the ever rising popularity of large open plan kitchen/family rooms there may be building work to be done.

Although at Emlyn Kitchens we are all about designing and installing beautiful kitchens, Ian’s wealth of experience and knowledge in all areas of building and surveying is often extremely useful for our customers.

In many cases you can extend your home downstairs to contain your new kitchen, or make more room upstairs in the loft to make room for your kitchen downstairs without needing planning, as it will fall under permitted development so we thought it would be good to outline these options below:

In short, PD allows homeowners to extend and make alterations to their homes without having to apply for full planning permission.

We have highlighted some points which you may want to keep in mind if you are considering gaining approval for a kitchen extension via PD.

Are you eligible for Permitted Development Rights?

The rights cover terraced, detached and semi-detached properties. Restrictions do apply if you live within a conservation area, own a listed building or live in a flat.

What kind of work is possible under Permitted Development rights?

Loft Extension

Loft extensions are one of the most common developments which are built under Permitted Development. In order to obtain a loft extension, the proposal must be contained within 40m cubed for terraced houses and 50m cubed for detached and semi-detached houses.

You can achieve an impressive dormer extension, or even an L-shape dormer which extends onto your outrigger within this volume allowance.

Ground Floor Extension

If you are looking to add some extra living space on the ground floor, Permitted Development may be an option but there are certain limitations and conditions that must be met. For example, single storey extensions must use materials matching the existing property to be in-keeping with the character of the area. The biggest impacting factor is the length and height of the extension. The new proposal must not extend beyond the rear of the original house by more than 3 metres (4 metres for a detached house), or exceed 4 metres in height.

What is a Lawful Development Certificate?

A Lawful Development certificate is not the same as Planning Permission, but it is proof that your works are lawful within Permitted Development. Having this paperwork will also come in handy if you choose to sell your house in the future.
