Forest Hill's sloping gardens present unique opportunities for garden rooms. Many properties backing onto Horniman Gardens or near One Tree Hill benefit from elevated positions that annexes can exploit beautifully. Local planning considerations around conservation areas mean thoughtful design matters here more than most places.
Ground preparation on SE23's London clay requires specific foundation techniques to prevent seasonal movement. Insulated composite panels maintain comfortable temperatures year-round, while triple-glazed windows face away from neighbouring properties. Electrical connections run underground from your main consumer unit, keeping installations discrete.
Twenty years working across Forest Hill means understanding which designs complement Edwardian properties versus 1930s semis. Each annexe reflects the character of streets like Canonbie Road or Sunderland Road.
