Deep retrofit old cottage

    Hi, offer a deep retrofit scheme that requires these mandatory measures:

    - Renewable Primary heating system (air source heat pump)
    - Advanced ventilation (heat recovery or demand controlled ventilation)
    - Air permeability reduction.

    Any idea if it be a good idea to deep retrofit a traditional stone cottage from the 19th century?
