Shame! I`ll just have to keep looking preferably for one who is friendly with the Building Inspector so I don`t have to mess my windows up!! grrrr

Let us know roughly what you get quoted & ask them what they will do for the money, they should suggest (even if build regs dont require) putting in insulation. In the picture it took me and one other guy 2 days to complete that particular floor

Thanks I`ll do that.

One builder quoted me £5750 without electrics. Didn`t like him though! Another £6,000 `ish but if I want to go ahead he will cost it out. Also if I want a downstairs toilet putting in then its about another £1000-£1500. Think I`ll spend it on a holiday instead.

£5750 without electrics? seem a touch on the steep side to be honest, whats he doing for the money? New entrance, new windows, new floor, freshly plastered walls, decorated etc etc.

Get on that plane!!!!!!!!!

Floor not sure wood or concrete, plaster board walls, ceiling, joinery, window,brickwork under window, insulation, 4 powr points, ariel, door through to house...approx £6,000
The other bloke £5750 - concret floor, ceiling and insulate, batten walls and plasterboard, brick under window, window, plaster, door through, skirtings etc window cill, remove rubbish and leave clean and tidy (but didn`t like him!!)

Not really sure how much the job should be approx so its a little hard..hubby knows less than me and is out at work so I tend to do all this.

Iv'e thought a little more about your quotes mum and as it happens your quotes arent that far out to be fair once you tally up the materials and labour etc. Down to you now I suppose whether you go for it or go on holiday. For that money though you shouls expect the insulation and electrics to be included.

I did my daughters house last year. The property was 20 years old and was the original show house for the then new estate as such the garage had been the office, had never been used as a garage and had "crappy" patio doors instead of a garage door. There were 2 low steps down into the garage. It was however only insulated to agarge standards.

Rightly or wrongly because of it's previous 20 years use we decided not to inform building control.

We decided to raise the floor on damp proof pads and run timbers of reduced size in both directions, ie in a grid pattern to reduce the size of what would have had to be 11" beams. On point to bear in mind, the original concrete floor in this garage was sloped by 2" towards the outside to drain the garage, so each beam had to be packed individually. A test drill proved the concrete was laid on jablite polystyrene.

A further 2" of polystyrene was fitted between the top row of joists, and water resistant chipbboard fitted over.

The patio door was removed and a upvc window bought to fit. The brickwork below was built up to window level in single skin, with a couple of air bricks to keep things fresh, and a stud wall spaced off to give 8" of poly insulation added, drylined over.

It is the warmest room in the house, the kids playroom.

Cost? totally DIY, was £1200, £400 of that being a wide 4 panel window.

Edit: Sorry reread your post and you say you did the drylining, anyway, what labour days did it take?

GM Cyclone, Did your DIY of £1200 include plasterboard electrics etc? Only reason I ask is that a lot of these new build garages are already "boarded out" and almost look like a normal room anyway - Just curious, also if you were to pay yourself £150-£200 pere man day how would this calculate for your time? Regards

Edit: Sorry, just reread your post and you did the dryling, anyway, how many man days would you say it took?

A bit hard to say actually, as due to an accident a few years ago, I can only work for a few hrs then give up till the next day. It probably took me a fortnight (14) of mornings, that was to do the complete floor, tooth out the brickwork and make good the lower wall, fit the window, and insulate. The electrics were in, so was the plaster board, but the board had only ever been done to enable temporary use as the office, it was on 2 foot centres and badly bowed. I/we, ( I did have help from 2 sons in law for a weekend), ripped the boarding out and dab and dashed the new stuff in. The electrics were "rearranged" to suit a kids room.

I did have the luxury that my son in law had a mate that ran a team of builders, he sent round a plasterer who skimmed out the new room for a "few drinks". Done in one day.

Couldn't obviously cost for time, or favours, but just trying to give folks an idea fo the material cost of the whole lot if such a thing id considered as a diy project,

Cheers

Fair enough, youv'e done well to get your mats for that price. It's always nice to have a friend that is in the building trade, One of my brothers is a senior quantity surveyor who scratches my back with costing large extensions etc however the other brother is a fireman and sisters work in care. I am forever doing building works for them and my parents, grandparents aunties/uncles etc as favours shame I don't get the favours back (short of my surveyor bro) Oh well I chose the trade I suppose + My brother might save me from a fire one day and I will deffinately need some care when in the future so it will come back one day :rotfl:
