Near the castle and station, terraces and older town houses have smaller rooms, shared walls and limited rear yards, so condenser position and pipe routes dominate the survey. Higham Wood and other later suburbs are more typically family houses with wider plots and, in some cases, open-plan rear extensions that gain heat through glass. Villages such as Hildenborough, Hadlow, Leigh, Penshurst and Tudeley add Weald and riverside houses where gardens help siting but distances, trees and period fabric still shape the design.
Bedrooms overheating under roofs, and living rooms opened into kitchens, are common reasons households look at a split system. The installer should size those rooms as they are used, not from the original floor plan. Electrics in older Tonbridge streets, and loft conversions above terraces, need checking before a second indoor unit is assumed to be a small extra.
