Extension - Do I need planning permission?

Question

We would like to extend our kitchen and bathroom on our bungalow, the extension would be one storey and would not be viewable from any road as our garden backs onto fields with 60ft trees between.

This would increase the house size by about 15%.

Also we would like dormer windows upstairs facing the back garden once again, would that require planning permission?

Any idea of costs for the extension including a nice new kitchen and bathroom?

UK answers only please.

Thank you!

Answer 1

I've just had an extension built, though double storey, I would advise you to speak to your architect.
I had to have planning permission, but my architect sorted all that out for me.
If you are extending your property by 15% then you will need to get it, but make sure you put the dormer windows on the same application (saves paying twice)
when i was quoted for mine, the price of a single storey was £17000. don't know what size comparison mine would be against yours, but you have to take into account that the foundations will need digging out!!!!
kitchens and bathrooms vary so much in price, and it depends on how much you want to do yourself. my dad and i installed my bathroom, so it was simply the cost of the suite (£600), but i didn't know where to start with my kitchen, and with that being a job that i would be less likely to want to do again, i had a firm do it for me (£8000 completed with tiling)
hope that helps you a little bit, i do not profess to knowing everything about building, but I can say i'm pretty clued up on living within a site!!!!!

You will probably need permission. The fact that the extension cannot be seen is immaterial. You should ask the planning department of you local council for advice. Remember it is not only planning permission you require. Your construction must also comply with local building bye laws relating to materials used and type of construction, drain layout etc.Job to estimate total cost of all this as a lot depends on the specification it is done to but would budget for £15 to £20 thousand.I assume you are replacing all the kitchen and bathroom fittings.

Answer 3

I think you do still need planning permission contact the council they will let you know.As for the cost my kitchen extension 25 ft wide cost 25,000 then it was about another 5,ooo for utilities and decorating.

Answer 4

you may not need planning permission on the extention !! its worked out on percentage of existing to new !!! you may require it for the dormer windows ( the people who draw up your plans can advise you on this !!!) you will need building regs !!!! this is where the council look at the plans to make sure all is to building regulations , they will come out and inspect the building in stages to make sure it is built correctly !!!!! costs :::::::::::::::ball park figures planes £500 ,building regs £500 ,the build4x4 meter kitchen plus bathroom £30,000 ,kitchen fittings £2,500-£10.000 b/room fittings £500-£1,500:::::::::total £34,000-£52,000 again it depends ???????????????????

Answer 5

yes you do get down to local council where the will have planning dept and put your plans to them
cost would be down to what buider you choose and what materials etc.

Answer 6
