Replacing pebble-dash with modern render - permission required?

tellisg

My semi-detached house is undergoing refurbishment and extension and I am hoping to change the existing old and damaged original grey pebble-dash with a new modern one such as K-Render in a lighter colour which I will also apply to the new extension. I will ensure this is compliant with building control.

However, my planning approval has the following condition 
"The materials to be used in the construction of the external surfaces of the extension hereby permitted shall match those used in the existing building"

Does this mean I will be restricted in what I can do? My house is not listed, not in a conservation area and several nearby houses of the same style/construction as mine had done the same - replaced pebble-dash with smooth render.

So can I just go ahead and do it or do I need to speak to the council planning department or submit an amendment or apply for new permission?

Any advice will be very helpful.

As long as you are just chipping off the outer layer (or going over the top), you shouldn't need planning or BC involvement. If the old render was being removed back to brick, and it covers more than 25% of the building, BC would usually require insulation to be added.

But as your PP state "match existing building", it may be prudent to check to see if a smooth finish across the whole structure is acceptable.

As FreeBear says, in your situation it is best to check with the planners.

Not following a condition of a planning consent is always a bad idea, and although the planners are unlikely to refuse your request it is better to have that in writing so there is no doubt - and so you'll have the proof that a future buyer (or their solicitor) might ask for.
