Sustainable Design Collective are an award winning architectural design and sustainability consultancy who provide services for Passivhaus and low carbon projects. 

"Hannah worked for us at Sustainable Design Collective as an intern. She conducted this role during the difficult Covid period where we were almost never in the office and she had to carry out the role with no face to face input.


She maintained and populated the Streak data base which was a crucial part of our marketing strategy. 

This involved emailing and phoning people who had expressed an interest in our architectural and building work, following them up  and writing again, with other admin work. Hannah was exceptionally persistent and reliable; we could trust absolutely that the tasks would be completed. Clients also reported that her manner was friendly.

She was  enterprising, suggesting other actions, refusing to be daunted by obstacles.

She is also very bright, quick to grasp what was needed. In addition and this is more unusual, she felt able to ask questions , both of us and of clients( (if for example their requests were unclear).  Thus she had the confidence to appropriately challenge us, point out where we were letting things slide.


I recommend Hannah, and Catalyst, without hesitation."
