Bungalow - Permitted Development Advice

[Dre4891]

Hi,

I'm having issues trying to get what I want via planning so I'm going to go down the PD route and max out what I can do. I've had a read through the 'Permitted development rights for householders' technical guidance but there are a few areas that don't seem clear cut especially around bungalows (it could just be my lack of understanding though 🤣). It doesn't help that my property and plot are an odd shape.

 

I've got a few questions, any help/advice would be greatly appreciated.

 

From my understanding I can extend out from either side up to 50% of the original house and out the rear up to 8m (subject to a neighbour consultation scheme), is that correct?

The extensions can't be more than 4m in height. I'm assuming a pitched roof is permitted as long as the total height doesn't exceed 4m?

Can the roof on the extension tie into the existing roof (pics attached)? Does the type of pitched roof on the extension matter? as in can it be gable ended, hip ended or is that irrelevant (pics attached)?

Can I add a dormer to the existing roof that faces the garden?

 

I've uploaded a site plan.

What would be classed as the width of my house the green or yellow arrow (house built circa 1804, I have no idea when the bit on the side was built. It's the bathroom)?

I'm assuming it'll be a struggle trying to get PD to extend out the way of the red arrow as it fronts a highway? Or could I argue that there's a substantial distance between the house and the highway?

I'm assuming the pink line is the principal elevation of my property (Back the in 1970's the driveway entrance was moved from 'Highway B' to 'Highway A' and a porch was added to the rear of the property facing the garden)?

 

Thanks for any help.

Before you go too much further it looks like you need to firmly establish what your principal elevation is.
 

The elevation facing ‘Highway B’ clearly used to be the principal elevation but moving the drive to ‘Highway A’ and the porch addition facing ‘Highway A’ may well have made that the principal elevation.

Thanks for your reply. That’s not the porch facing ‘Highway A’ that’s the bathroom. There are no exterior doors on that side of the property. The porch faces the garden.

Ah, I misread, soz.
 

So the principal elevation is most likely still facing ‘Highway B’. I found the Gov guidance useful but don’t recall enough detail to advise. Have you read this?

Yea that’s the document I read but like you said, it doesn’t go into enough detail to get a clear answer (or I just didn’t understand it 😂).

I'd say the principal elevation is the one facing highway B. I'd use the yellow dimension to assess the width of the house for the side extension. No side extension would be PD facing Highway A - it's a highway. Yes prior approval needed for an 8m rear extension and yes the 4m height is to the ridge of a pitched roof. 

 

The type of roof is not a problem - it's PD. Be aware the section of roof that runs back from the plan of the extension onto the existing building would be dealt with under Class B because it's an extension to the existing roof. A dormer would be allowable on the rear subject to the total volume of roof extension (some used by the extensions as mentioned) and the other requirements regarding height and position etc.

 

Finally it's not 50% of the house area, it's 50% of the curtilage minus the house area. Your extensions and other buildings (garage etc) should not use up more than 50% of that figure.

You could extend along the blue arrow up to 50% of the original width.

 

You could extend along the black arrow up to 4m or 8m with Prior Approval. But only if the small part sticking out is not original.

 

You cannot extend along the red arrow without Planning.

 

You may be better off speaking to and engaging a local Planning Consultant so they can review the Planning history, establish the restrictions and advise on the development options.
