Hi

Due to wife expecting our second child next year I am looking to convert
part of my detached garage into an office, it is brick built with a flat
roof and concrete floor a window will also be added. I intend to insulate
all walls by using a timber frame and then putting plasterboard over it, i
will also be insulating the dividing stud wall along with ceiling and floor.

The new room size will be 3m x 3.3m and i think i will need approximately
48m sq of insulation,. What type do you think i should use?

Is it ok to use Chipboard for the flooring?, this will be on a timber frame
on top of a DPM. I would also like to line the walls with chipboard over a
DPM to give even betting insulation before creating a timber frame, is this
a good idea?

Thank you in advance for your comment & opinions.

Thanks
Tom

Sounds reasonable - but don't forget to check on building regs. Being a
detached garage, it was probably exempt - but won't be when part of it is
living accommodation. If the other part is still a garage - or even if it
may only be used for storing flammable materials - you'll need suitable fire
protection between the garage and office parts.

I'm not sure whether you'll also need planning permission for change of use.
It may be as well to check.

if its for habitation, you'll want insulation in your new wall cavity
and also under the floor.
