Local context

Why Muswell Hill needs a specialist

Muswell Hill is Edwardian villas and terraces. The streetscape is dominated by edwardian villas, 1930s semi-detached, which means design decisions — roofscape, rear glazing, side returns, mansards — must respect the period rhythm of the row. Barnet planning (Barnet Council) decides applications here. Most permitted development rights apply normally in Barnet for residential extensions.
