Bednobs has already asked my first question. In my experience of doing this, I can tell you that, in the early stages of the build, you shouldn't need anything like the whole 110k to get it out of the ground and on its way.
There's no point in taking out a bridging loan and have it sit in the bank doing nothing for you. As Bueno says, it can be quite expensive.
My first call has always been my Bank. There are various arrangements available for self-build finance. I do it as a business, but it doesn't have to be so for you.
Arrange an overdraft facility. Initially, you take out small amounts. Then, you only pay interest on that amount, not the whole lot.
Cash advances will be staged. As the build progresses, there is more and more value in the property, thus allowing the Bank to release more money, but with increased security for them against the borrowings.
Research the Self-build market. There's a lot of advice available.
Good luck.
