Quick answer
Builderr serves the small residential population of the City of London (EC1–EC4), primarily in Barbican Estate apartments and the handful of Georgian terraces near Smithfield. Conservatories and orangeries are uncommon here given the predominantly commercial and high-density residential character, but private garden spaces attached to mews properties and Barbican garden terraces have been successfully glazed. Where applicable, lean-to conservatories cost £35,000–£95,000 and full orangeries £60,000–£185,000. The City of London Corporation's planning team applies strict design criteria; all residential glazed extensions require full planning permission given conservation area designations across EC1–EC4.
The City of London Corporation operates its own planning authority separate from the London boroughs. Conservation area coverage is near-total across EC1–EC4 residential pockets, meaning permitted development does not apply. Early pre-application engagement with the City's planning and design team is essential.

Planning in City of London
Local planning rules for conservatories & orangeries in City of London.
The City of London is the smallest and one of the most planning-restrictive authorities in the UK. The Barbican Estate is Grade II listed (with Grade II* elements) and the Golden Lane Estate is Grade II listed — both with Article 4 directions removing all permitted development rights. Conservation areas cover virtually the entire Square Mile including Smithfield, St Paul's, Bank, Whitefriars, Postman's Park, Fleet Street and the Tower environs. External alterations, new openings, replacement windows and even some internal works to listed flats require Listed Building Consent. The City's Local Plan and Heritage SPD require pre-application engagement; consultation with the Barbican Listed Building Management Guidelines is essential for any Barbican project. Tall building policy, protected viewing corridors (LVMF) and St Paul's Heights add further constraint. Determination times are slower than outer London — typically 10–12 weeks with extensive officer engagement.
Our planning team handles the full submission for City of London addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your conservatories & orangerie is permitted development, prior approval, or full planning before you sign anything.
