Builders/Tradesmen - Rough Cost of Job?

[Ceri JC]

Hello Mighty Org,

I'm buying a new house. It has a free standing double garage, which whilst it has a proper (slate) roof and is structurally sound, it currently has 3 walls and a 'front' with no doors on it and is built out of wood. It is on what looks like a sound concrete foundation. There is already an electrical line running to the building.

I was wondering if anyone in the trade, or with a knowledge of these things, could give me a very rough estimate of what each of the following would likely cost:

-Line the existing structure with bricks and provide some sort of lintel, so I can have two garage doors fitted to it (NB the doors themselves are already in hand).
-Fit a damp course to this brickwork.
-Render the interior smoothly in cement and paint it white.
-Fit 4 x double mains points
-Fit 3 x electrical strip lights (with some sort of strong cover/cage to stop me smashing them, when I inevitably clout them).
-Running at water line from the mains or house (about 7 Metres) and fitting an industrial sink/mains-connected 'parts cleaner'
-Adding a single sensor (for the garage) to an existing alarm system (in the house).
-Painting the floor in that really strong, shiny, sealed garage floor paint that helps keep cement dust to a minimum and makes cleaning up oil spills etc. much easier.
-Insulating the roof and connecting the garage to the house's existing central heating system and fitting a radiator or two to it.

Property is located near Chepstow (South Wales), in case that makes any difference.

I just want to know so I can do some sums on the total cost of moving and re-mortgaging and see how much I need and what I can afford to do on the garage.

Thanks in advance.

Think it maybe cheaper to flatten it and start again I would also check on the planning side of things as if its made out of timber it may not be classed as permanent structure were as brick would be.

I don't know but always best to be safe than sorry.

That isn't an option, unfortunately; the house itself is listed. It is a condition of the planning permission (which I have sought) that it stays the same aesthetically (bar the addition of the doors) from the outside. I accept that this will likely not be the cheapest option.

Why brick indoors? Cheaper with insulating blocks and better to paint.

I agree, stud and insulate with celotex panels, much more thermally effecient than brick.

Also, with respect, I think you're barking mad to run radiators in there, might as well burn £20 notes, be cheaper.

Excellent, this is precisely the sort of thing I was after!
So, what sort of ball park figure would I be looking at to do this?

NB: I fully expect the heat and water options to be spendy (and that I probably won't do them); I just wanted an idea of how much money they would cost in case there's some money left over. :)
