I rent a workspace outside of my home, I'm paying less than 150 quid for a room in a light industrial zone. Gives me space for my fun stuff as well as work. I love having my own space, and it's very affordable.
I was just looking at the prices for city centre commercial rental in my nearest town. Huge spaces available, it's generally more per month, and I'd be worried about the rates threshold, but at a lower price point we'd be in business.
I think there's something to that. More people using a centre for work would create more opportunities in towns.
Again, I think the challenge the UK has is the gross differential between incomes and the cost of buying or renting property. Unsustainable, and very much part of these morbid symptoms.
