H & I are really struggling to decide what to do here. We are in a fortunate position to be able to do our house up. We plan on staying here 10yrs. Benefits of this proposal are solving issue v dark dining area and giving us more room for table, replace knackered flat roof with smart new one with skylight, again bringing in more light, and replacing unreasonably cold /hot conservatory with usable space. But, it's a lot of money to not add any floor space...
