Renovating a 136sqm 1920s redbrick house

newbie_diy

I think I posted in wrong forum yesterday..

I am in the process of buying a new house, an old 1920s redbrick house. I would like to completely renovate whats there, no extension needed. I would like to improve air tightness and insulation, replace windows and doors. I like the thought of underfloor heating and polished concrete floor. I would like some advice:

1. Is air to water and heat recovery ventilation the best way to go
2. As its red brick exterior, internal insulation is only option. Or is it? Can you keep original features inside and insulate?
3. Should chimneys be blocked up or is installing stove inserts sufficient for air tightness?
4. Is it possible to get an estimated cost per sqm so I can estimate if I have budget for such a project before buying house?

My main concern is having a warm energy efficient hosue once finished and also that I wont have to go ripping anything out 10 years down the line due to green energy requirements?
