Dear all renovation expert, architect, designers,

I wished to transformed my roof all of the 800sq ft to an attic that I can use as a separate space for gathering, reading, music and also relaxing.

- Some feedback that it's only good for store room and it's hot
- Others said that you can absolutely use the space because you can put in good heat insulation that will block more than 90% of heat

Do anyone of you have experience on it?
- How much it cost?
- Any good contact and portfolios that I can refer to?
- Do you need to submit plan and get it approved?
- What other things you need to take note?

Old wodden type and also there are two large tanki above.

Why is it so hot?
I understand that with proper insulation you could reject 90% of the heat.
