Help finding architecture firms who focus on re-using and re-cycling for small community projects

A repost from Reddit as I wasn’t aware of the quick questions rule, apologies!

This is a bit of a long one, but I hope it is meaningful to you in some way and you can help me.

Me and my girlfriend (who is Malaysian) are moving to KL in Jan/Feb next year. She's an architecture graduate from a uni in the UK where we are now and wants to help local communities in Malaysia by creating spaces/buildings/structures that serve them in a meaningful way, but she wants to make sure that these projects use locally sourced materials and waste so they are as environmentally friendly as possible. For example, restoring abandoned buildings or re-purposing them is an area she wants to explore.

So far, most of the architecture firms she is seeing online are building the standard condos or office buildings which we are all accustomed to seeing in most bigger cities around the country. She is finding it hard to find firms who focus on smaller projects which re-use and recycle materials/structures and is getting disheartened that such architecture doesn't exist in Malaysia. I am certain this isn't the case so I wanted to ask if any of you is aware of such architecture firms or places where she can find and network with the right people.

Thank you in advance and wish you all a great day ahead!
