So, for me in today's economic climate I just want some additional space rather than move. I'm after something well insulated that I can use as an office and these modular extension/ conservatory alternative products seem pretty good.
Thanks for the point on regs. You're right. I hadn't considered the external doors on the property which it would seem would need to remain as is.
If I buy it or one similar, I will share my story on here as to how i get on with it.
