Does anybody know where I could possible get hold of cavity wall
specs ? basically I'm looking at managing a extension project myself
but I want to be sure that everything is done right and according to
BC. Some of the builders I have had in for a quote tell me that for
the floor be it solid or wooden, they have to dig about 8" down and
then build it up with a mixture of hardcore, insulation and DPM, is
this correct ?

Any advice/help will be greatly appericated.



The first step is to commission an architect to draw up the plans.
(They do not have to be done by an architect but need to contain a full
construction specification so it is often an architect who does them)

He will visit the site to measure up and discuss with you what you want

The plans will contain all information regarding footings construction
materials insulation roof structure etc. He would also commission a
structural engineer should one be needed

These plans are then submitted to the local council building department for
approval.

The architect will normally know if the plans will also require planning
permission

Once the plans have been passed you would then use them to get quotes from
builders based on those plans or from individual tradesman for each aspect
of the work

When I last did this I also ordered all materials and contracted in such
labour as I needed so essentially I acted as the builder would have done

As project manager you will then supervise the builder/tradesmen to see that
they follow the plans and do the work to the standard you require
you would notify the building control dept as required to inspect each stage

I know other people who have started the process by asking a builder for a
price based on talking with them and then the builder arranged for the plans
to be drawn and submitted and then carried out the work
