This is hypothetical at the moment as we haven't found a house or anything, but my dream house has a massive kitchen/dining/living room all in one, but with a separate lounge-type room that would be a retreat at the end of the day, totally separate from the big room. An adult space if you like. So as most houses have that room at the front, with the kitchen and dining rooms at the back that lend well to being knocked through, the obvious choice would be to extend out the back to make this room a big big room IYSWIM.
I'm wondering (mainly on grounds of cost) whether an extension would be the say to go - and this would be the ideal, or whether a 'nice' conservatory would suffice and be cheaper? I'm thinking that by opening up as much of the back wall as possible and having one of those folding doors between the house and the conservatory space, and keeping the floors level, that you could still get the illusion of one room but could still close the door to keep the heat in etc when not in use to save heat.
But what I dont know is whether having a conservatory instead of an extension is actually much cheaper, or whether it would be a bit of a false economy? I'm not worrying about re-sale value as our next house will be where we live for many many years but I'm trying to get an idea of what we should be looking for based on what is best.
I hope that makes sense. Also, we will have to live in the house while any work is ongoing so I'm thinking about disruption too. Although obviously I want the finished product to be something we love and don't regret.
