Yes . I've been there and done that , you haven't said if you want to build up or along side . Not that it really matters.
1st get the plans drawn up if your in UK that will cost around £100 .
2nd Get planning permission , that won't cost a lot.
3rd Really shop around for people you may already know or have been recommended by friends to give you piece meal estimates . foundations brick work plumbing etc etc!
4th Do as much as you possibly can on your own .
All this will take quite a bit of time but cost it against a 'one off job' quoted by a builder and you will save more than 50% of his price!!
You can trust me, I'm not a builder!1

As a general rule of thumb allow between £100-£150 per sq foot. This will give you a good idea of what you will spend. What you have described seems to be about £30K to £40K.
You will need, initally, to get the land surveyed. This will cost in the region of £500-00, but will form the basis of all applications that you will have to make.
What you have described seems larger than what would be allowed under permitted development rights, so you will need, at least, planning permission. The drawings for this are a bit more than £100-00. Allow for nearer £1000-00 for these.
After receiving permission you will need to get Building Regulation Approval. The drawings for this will be in the region of £2000 to £3000. You will also need structural engineering calculations.
Once you have achieved all this, you can begin to go out to tender. For this sort of job I would recommend that you go to a minimum of 3 contractors, but more if you want.
Finally, you need to choose a builder that you have heard good things about. Basically ask to see previous examples of his work.
For this sort of thing, you would be foolish just to employ a builder unless you have previous experience of the building trade, and you don't seem like you do. You have no way of actually checking the quality of the materials, nor the work.
Employ a professional. They may cost more, but they know their way through the red tape, and they give you peace of mind at the end of the day.
Good luck.

Depending on where you live, any kind of building extension will cost you about $100,000 and up. You have to have a foundation--very expensive--the extension, the new roof, added wiring, added heating and a/c units, and perhaps even an additional furnace or a/c unit because what you have might not be capable of serving the additional space; maybe more plumbing if you want another bathroom (which is often a good idea). A word of advice: use a home improvement contractor who is properly licensed with your state or county's home improvement commission.

You need to get quotes from local builders, get at least 3. They should give it to you broken down to include labour materials etc. It would also be wise to get an achtitech to draw up the plans first so the builders know exactly what you want. On a final note makes sure you get reputable builders ask to see references/qualifications etc.

this is a loaded question, It really depends on where you live. Cost vary region to region. the best advise I can give you is to contact several contractors to get es-testament's. ask for cost per square foot. Find a contractor with good references, ask to see other projects he has done like your request. Make sure he is insured. and always contact your local government agencies for permits required etc. good luck!

Your insurers are having a snicker. become the precise nature of the valuables shape a characteristic of the notion variety? I doubt it. you have been paying fees based on the dimensions and variety of the valuables. they might't substitute the goalposts after agreeing to insure you and taking your money. As mentioned this is one for the coverage Ombudsman. Pity you probably did no longer call those bastards so as that it would desire to placed them to shame and clever up different potential purchasers.
