Pull 3rd bedroom out with existing roofline, pic included

[James2520]

I have a 3 bedroom ex council house. The front 3rd bedroom is only 6'x6' but there is a 2' overhang of the roof over the end of this bedroom. I'd like an idea how much it would be to complete structural work (floors and brickwork) and to put the original front facing window back in to make this an 8'x6' room without touching the roof and perhaps making a small porch below it for the front door. I can source windows and doors for downstairs porch myself so really am looking for price of bricks laid and floor supporting work. I can extend radiator pipes and remove sockets from the wall and replace them myself and obviously know it will need replastering and new carpets etc.
My next door neighbour has had hers done but her late husband completed it and she knows nothing of how they went about it.

Why dont you post pics of inside and outside, and the neighbours completed job if thats possible?

I have a google maps screenshot of the front of the house and the next door neighbours in my uploaded images but I'm not home for a while with work to be able to take inside photos. Any ideas?

Its a pretty straightforward job that would only need Bldg Regs. I have no idea about costs esp. in expensive cambridge.

There are possible variations - but they would be more expensive, such as running a new porch area (as the neighbour's) or an extended front room or hallway.

As this is an extension on the front it would definitely require planning permission.

You are right, i advised the OP wrongly, Planning Permission is required.

 

[James2520]

Thanks for the replies, I thought planning permission may be required but wasn't sure. I wouldn't extend the lounge or hall area like the neighbour as I house two cars on the gravel front and wouldn't want to lose the ease with which I currently swing them in from the concrete driveway you can see to the left of the picture.
Does anybody have any idea about the concrete in front of the front door, it is poured at the same time as the house but I guess I'm hoping too much to presume underneath it is going to be sufficient for building control to accept it as the correct foundation type for a porch and the upstairs extension, although it is still under the house's roofline?
My neighbour said they originally built the houses this way as they were trying to prevent large families moving in, although with the roofline and the way the bedroom wall turns inwards, it is massively frustrating years later, particularly when it obviously saved no money on building costs at the time.

I guess you should go for completely new foundation, so that you don't need to spend on the maintenance of later. Also, you will not be having any issue with the building regularity body.

That`s about right from the Old School Socialist house building governments post War

Ok I guessed new foundations would be needed, there is no guarantee of what's under there. Any body got any ideas of costs involved? Im guessing new joists, floor boards, double skin brick wall built by a builder, small-scale plans/drawings and planning permission.
Is there anything glaringly obvious I've missed?
I have very little experience in costing things to be honest and have managed to get through most DIY to the house through friend's help, but with the front of my house being open, I know I'll need to use a pro.

I will add I'm in Cambridgeshire, but not expensive cambridge. Its Peterborough, some 35 miles away if anybody thinks that could affect tradesmen's rates at all?

They do a lot of Denver Pop Tops here in Denver which is a local term referring to adding an additional floor to an existing structure. It is an expensive process. If you're not in the business I suggest contacting a structural engineer and/or contractor to give you an estimate of cost.
