Existing House on Site:
- An existing house on a site can be crucial for securing planning permission on what would otherwise be a greenfield site.
- Planners may require you to retain and incorporate the existing structure into your plans.
- This option is often more expensive than demolishing and starting anew, with conservation issues also needing consideration.
Half-Completed Houses:
- Less common than in the past but still worth considering.
- If the house is severely damaged or lacks adequate insulation, it may be more practical to demolish and rebuild.
- Builders generally prefer working on new builds rather than existing structures, potentially adding a risk premium to the price for renovation projects.
