I,d say £30 tops for us.
I also have commercial twice that size at £25.00 same as rugby.
Been out pricing houses quoted £30.00 for slightly bigger but all georgian so nightmare, quoted £30 to dears . left a week we have a weekly job so looking for work there offered £25.00 six-weekly including frames, but still to dear.
There is still a lot of cheap domestic, this house is worth £600,000 + k so got the money.
