Passive house would be great to do / have, but it's diminishing returns.. like trying to get a final kg off the weight of a bike.. We pumped all the walls and redid all the roof insulation to current standards, new windows and doors.. new rads and electrics too.. It all just depends on budget.. Also build in a reasonable contingency as stuff will happen!!!
