Award-Winning Design & Build for Notting Hill's Iconic Properties
Notting Hill's stucco-fronted Victorian terraces, colourful pastel façades, and garden square architecture make it one of London's most visually distinctive residential areas. The properties here — typically grand four and five-storey townhouses divided into flats, or whole houses worth several million pounds — are almost all within conservation areas controlled by either the Royal Borough of Kensington and Chelsea or Westminster City Council.

- ARCHITECTURE
In-House Architecture — RBKC & Westminster Dual Experience
Notting Hill straddles the Royal Borough of Kensington and Chelsea and Westminster City Council. Our architects submit to both authorities and understand their different conservation area policies and application requirements. The Ladbroke Conservation Area under RBKC and the Westbourne Conservation Area under Westminster have distinct character appraisals and design expectations — what works in one may not work in the other.
The integrated design and build model ensures our architects design with construction costs and buildability in mind from the outset. For Notting Hill's grand stucco-fronted townhouses, this includes understanding the structural implications of basement excavation, the conservation requirements for façade restoration, and the sequencing of work within tight urban sites. Every project includes: measured survey, concept designs, 3D visualisations, construction drawings, planning applications to the correct authority, heritage statements, structural engineering, and building regulations via LABC. All included in your quote — no separate architect fees.

Conservation Areas
Ladbroke Conservation Area (RBKC) is one of London's largest and most strictly protected conservation areas, covering the garden square layout, stucco terraces, and communal gardens that define Notting Hill with strict controls on all external alterations. Westbourne Conservation Area (Westminster) covers the northern edge of Notting Hill within Westminster with different policies from RBKC but equally protective of the area's character.
