Playhouse concrete base
i need a base for a child's wooden 2 storey playhouse and am getting quotes which vary widely in price. what should I be finding out from the quoters ? my base will be 8x 10 if that helps?
To be honest this is a relativley easy task and alot of homeowners would take this upon themselves. You need a good sturdy and level base to begin with then corden of the section you are building a base on. The cheapest method would be to build a frame work youself and mix concrete and actually do it yourself. I would imagine prices would be very different on this depending on exact materials and the companies size that is doing the work. Make sure they are creating a base of a very decent thickness and depth into the ground. Hope it goes well.

A light duty external floor slab would be required here, laid on a well compacted sub-base.
The works would involve, in this order
1. Excavate oversite, dispose of materials to a depth of around 150mm. Compact the ground.
2. Place crushed material / MOT type 1 with a sand covering to a depth of 150mm, well compacted ie back up to ground level
3. Set up the formwork for the actual base, fill any gaps around with more sand/ballast
4. Pour a ready mixed concrete (grade PAV 1 or similar) 100mm thick
5. After a week or so, remove the formwork. OK for light foot traffic
Your finished floor slab will then be approx 100mm above ground level.
After about a month the concrete will have reached full strength.
Without asking for exact specifications from a builder, you are likely to get difference in price as each person may allow for slight variations on the above, more or less labour, and different materials depending on where they buy it.
Any queries, please let me know, thanks

To be perfectly honest, you get what you pay for these days. I agree with the way Blackat Demolition has told you and it would the more costly way BUT the correct way. The finished floor level needs to be above finished ground level but it depends on where you live, what access you have to the area and what concrete finish you require as to the final cost. Go for the middle quote but make sure you know what you are getting/paying for, specification wise.
