Mayfair, Soho, Fitzrovia, Victoria and Marylebone sit inside Westminster and behave like five different markets. Mayfair and St James's are period buildings with small floorplates, listed interiors and hedge fund budgets. Soho and Fitzrovia are media and tech in converted stock with awkward access. Victoria is large modern floorplates around the station. Westminster's planning department is among the most active in London on facade, signage and listed building consent, so allow time.
