Haydn Davey Extensions, Remodeling and Repairs Projects:
Extensions, remodeling, and repairs of domestic (residential) properties are typically regulated by local planning and building control authorities. The criteria for each activity can vary by country or municipality, but generally fall into several broad categories, for example:
Size and scale: Must not exceed a certain percentage of the original house volume or footprint.
Height restrictions: Single-storey or two-storey limits; not to exceed the main roof..
Overview of criteria typically considered for domestic extension - repair building projects:
Planning and Legal Requirements:
- You’re increasing the footprint or height of the building.
- The project significantly alters the external appearance.
- The extension impacts neighboring properties (e.g., overshadowing, loss of privacy).
Building Regulations Compliance:
- Structural changes (e.g., removing or adding load-bearing walls).
- Electrical, plumbing, or drainage modifications.
- Insulation, ventilation, fire safety upgrades. Any change affecting energy performance (e.g., windows, heating).
For Repairs (not expansions):
Repairs usually don’t require permits unless:
- They affect structure, fire safety, or public health.
- You’re working on shared walls (Party Wall Agreements in the UK may apply)
- You’re replacing components with non-like-for-like materials (e.g., replacing wood siding with brick)
