Advice on next career path?

I am based in the UK and have a Masters Degree in Architecture. I have worked as a Part II Architectural Assistant for three years and I'm not really happy with the experience so far.

The work culture consisting of heavy workload, back-to-back deadlines and unpaid but almost expected from you hours/labour, the little pay (at the end of my three year mark I got up to £25k from £22k) coupled with certain areas of the profession itself such as the technical aspects, supervision and coordination between contractors/suppliers/clients has created a bit of an aversion to the field. I am anxious when it comes to the latter and although I have done this as part of my job so far, I was positively stressed while doing so.

I dread thinking about having to work/study extra to sit the exams to become a qualified architect at this moment. I'm not sure I want to be one.

BUT I like design and in fact I think I like designing the interior architecture ( bespoke furniture-materials-finishes etc) of the spaces more so than anything else. I love being given a space (preferably residential) and designing the elements that could go in based on the client's breed. I am a sucker for the bespoke furniture especially.

Where I could go on from here? Is interior design I should be looking into? Or something a little more tied to bespoke furniture and what could that be? Any advice is appreciated really!
