Just starting a loft conversion my self - if you are a semi competent
diyer consider this.
Planning should not be a problem for a bungalow.
New joists can be placed on existing wall plate or hung from wall plate
- I'm using the new composite I beam wooden joists - go to Travis Perkins
etc and they design and quote for you - all accepted by the Building
Control Officer - also lightweight and straight so can be handeled by one
person.
Insulation will be a large part of the cost - needs to be 0.3 for
refurbishment. Mines going to cost 4-5k (proably 15k if done by a builder).
