​

Merton-Specific Quirks:

Croydon’s a mix, and each type of home comes with its own realities:

• Victorian & Edwardian terraces (common)
  → Ideal for side return and rear extensions
  → Often require structural steel for open-plan layouts

​

• Wimbledon & premium areas
  → Larger extensions and higher-spec finishes
  → Greater focus on detail and design

​

• Tight access & logistics
  → Limited side access on many properties
  → Material handling and site organisation are key

​

• Planning sensitivity in certain areas
  → Some zones have stricter requirements
  → Experience helps avoid delays and issues
