Have a look at this guide on the regulatory side, and check that you're getting what is necessary elsewhere in the house> https://www.housing.gov.ie/sites/default/files/migrated-files/en/Publications/DevelopmentandHousing/BuildingStandards/FileDownLoad%2C1657%2Cen.pdf

The fact it is a truss roof assume you've got an engineer out to look first and see if possible. Seen some where builder dictates cutting trusses and not pretty.
Builder usually does whats easiest/cheapest for him, not always right.....

Assuming pitched slate/tile roof, ensure Continuous air-tightness/ vapour barrier on warm side of insulation. Ensure continuous insulation overlapping with wall insulation. Ensure Continuous ventilation on outside of insulation ie air gap underneath roof felt.

Thanks everyone he's has shown to architect the drawing to make sure It can do it.No I won't be classing it as a three story.He will be doing it to regulations and it will be certify.

Thats not a choice for you to make , it either is or it isn't a habitable 3 storey

Sorry, but you are being led up the garden path here. You are creating a 3 story house.

Builder and architect are not qualified to ok this work. The only person is a structural engineer who will provide a certificate on compliance with Part A (Structre) of the building regulations.

Thanks everyone for input I was told it’s not class as a 3 three story house.Builder put my mind at ease and has done this type of work roof before with an engineer.Thanks again.

Perfect, so you currently live on a bungalow.
Doing the attic now only creates a 2 story house, so you have lesser fire safety regulations.

What others are eluding to, is that, it sounds like your attic won’t be a ‘habitable’ conversion, in a building regulation/ legal sense.

If your happy with a storage space, and don’t plan on having people sleeping in it, then best of luck on your project

You sound like you are being taking for a ride.
How will it not be a 3 storey but still meet the fire regulations?

I look forward to your post in 3 months asking why is this wrong and what do I need to sort it.

Honestly, why start a thread of your evasive with questions from the very people you are asking for advice from.

Not looking for advice. Looking for confirmation that they’re right.

surely it's possible to meet the fire regulations without classifying as "habitable space" (aren't there roof-height requirements for the latter anyway which are difficult to meet in most attics)?

Fire Regulations still apply whether its habitable or storage or games or office etc etc
