Mayfair Licence to Alter is an estate-and-freeholder product first. Great-estate design standards and freeholder surveyor packs decide the brief before kitchen furniture is drawn. Freehold rear digs are a different product.
Lateral apartments and mansion stacks fail freeholder review on acoustic floors, fire separation, riser moves and wet-area waterproofing more often than on planning bulk. We freeze those technical items before open-plan layouts are sold as freeholder-ready.
Listed interiors and protected fabric mean freeholder packs must not invent openings listed building consent has not cleared. Dual tracks are sequenced from one measured model.
Compared with Belgravia Grosvenor-stucco freeholder culture, Mayfair more often turns on W1 great-estate handbooks and mews-versus-mansion building type. Compared with Marylebone estate streets, Mayfair more often pairs freeholder packs with listed-interior sensitivity even for “internal only” works.
Sequence: lease and estate/agent process → measured demise survey → design freeze for openings and wet areas → freeholder/estate pack → Westminster planning if external → building regulations → tender.
Client pack: lease extract, estate guidance if any, photos of wet areas and common parts, and a clear list of structural openings. Cosmetic-only packs are refused when structure or fire is engaged.
Programme risk is freeholder and estate surveyor time plus dense W1 construction access. Method notes freeholders expect must not invent suburban delivery routes.
Building control is separate. One technical story prevents Mayfair freeholder and building-control packs from inventing two fire strategies on multi-unit buildings.
Mews freeholder packs raise shared party structures; mansion packs raise stacked acoustics. Building type decides the first freeholder sheet more than the Mayfair label alone.
Fees follow estate and freeholder requirements. Freeholder surveyor charges are usually separate. Fixed professional fees are confirmed only after the lease, works list and agent process are clear for this pin.
External vents, plant and elevations can re-open Westminster conservation questions. Freeholder packs and planning sheets must share openings and materials.
Mayfair LTA is great-estate freeholder technical coordination under Westminster — not a householder rear-extension template and not a dig brief for freehold lower-ground rooms.
Lateral flats need freeholder packs that map every notifiable owner early so party wall awards do not stall after freeholder principle is agreed.
Previous freeholder or estate refusals on the same building are reviewed so the pack closes known risks rather than repeating them.
A complete Mayfair Licence to Alter appointment covers lease and estate process, measured survey, freeholder technical drawings, and sequencing with planning and building regulations where those tracks apply on this pin.
We refuse to treat freeholder approval from a different estate street or a different conservation edge as proof for this pin. Method notes and openings are written for the actual structure and management regime in W1.
