SHELL LOFT CONVERSION STEPS

[DIY2025]

Hi,

I have just had a shell loft conversion done and I need some assistance in understanding the steps needed to complete the loft conversion to a finished state.

I am a competent DIYer - would some one be able to help me to understand at what stage would I do the first fix of plumbing,electrics? would that be after stud walls? after insulation?

Any tips and guidance will be appreciated.

Would depend on the plans , we are not psychic .

Attached is the loft plan.

Stairs will be put in by the builder.

I will need everything else to be installed:

1)electrics - new ring
2)lighting - new radial
3)heating - radiators
3)hot/cold water for bathroom

You need to talk to the building inspector

You will not need a ring. A 20A radial will be plenty.

Depending on the existing circuits, you may be able to extend them.

Ditto the lighting.

Thank you.

which order would I get the internal works done?

1-stud walls?
2-first fix electrics/plumbing?
3-insulation?
4-plasterboard?

Agreed, loft conversions are a minefield of regulation and you have to stick to them, I did mine 15 years ago and can only imagine it's even more strict now.

You need to talk to the building inspector

Can I ask how you did the shell conversion? I'm about to start my project

 

[DIY2025]

I specifically asked the builder to build me a watertight shell, including windows and stairs.

I have had drawings done by architect which speciies all the room sizes, windows, insulation etc.

I did it this way because i am competent at DIY and fell comfortable doing stud walls, insulation, etc.

I just need aome guidance on which order things should be done.

I know that after the ridge beam goes in, i need to inform the building inspector.

 

[Murdochcat]

What about the SE ?

 

[DIY2025]

The structural calculations were also provided with the drawings - i spoke to the building inspector and he said the before work is done on insulation - he would to see how all the besms have been installed

 

[freddiemercurystwin]

Surely having a 'shell loft conversion' already completed the ridge should already be in?

All in, the exterior shell works is almost done except windows and stairs
