Clivvy, if you do a search I asked a similar question earlier on this year and there were some bang on points made :thumb2
In the end we went for patterned concrete and absolutely love it.
Gravel, discounted, noisy and messy well discussed earlier but also we spent quite a bit on oak flooring, I couldn't bear to think of someone in chunky shoes trampling it in
Block paving and slabs, look good to start but ALWAYS shift. We had block paving, properly done and it looked tatty after about 3 or 4 years, getting on our nerves by 7 over the moon to see it skipped
We did a lot of research (on line and wandering the streets being nosey) and fell lucky with a good local tradesman via the rugby club to do the concrete. He explained the ins and outs at great length down to the different concrete mixes, expansion gaps, depth for base, surface finish, maintenance....the lot. very anoracky but interesting :augie
His CV was impeccable. Amongst the jobs he's done is the national contract for Kentucky fried chicken drive through, Blackpool Sea Front, Flamingo Land and loads of other big uns.
Best of all he did a drive just down from us nearly 5 years ago and it still looks great.
He's good and theres loads of ideas on his site

As far as lifting the drive for work goes that was one we asked and he didnt bat an eye lid and referred us to one where that had been done, you couldn't see the join
in any case I aint lifted our drive to do anything in over 25 years!
The point Im making is research and select carefully. The cheapest isnt always the best option and you do get what you pay for :thumb2
