Prime London's Trusted Luxury Builder

Vine Construction luxury London home renovation — Kensington townhouse extension with heritage sash windows and stone facade

Vine Construction is a family-run firm of luxury London builders specialising in the discreet, high-specification renovation of period townhouses, mews properties and prime residential estates across the capital. Since 2008 we have delivered complex home extensions, loft conversions, basement conversions and full period property restorations for owners of Grade II listed homes, conservation-area properties and estate-managed leaseholds including Grosvenor, Cadogan, Portman and Howard de Walden.

Our teams combine traditional trades — lime plastering, timber joinery, lead work, stone masonry and traditional sash window restoration — with modern building science: airtightness detailing, MVHR, underfloor heating and heritage-appropriate secondary glazing for acoustic and thermal upgrades that preserve historic character. Every project is led by a dedicated contracts manager, delivered under a JCT contract, and covered by £2m public liability and £10m employer's liability insurance.

Secondary Glazing for Sash Windows

The heritage-friendly way to make original windows warm, quiet and secure. Preserve the period aesthetic while meeting modern performance standards.

Listed-building friendly

No alteration to the original window frame or façade, so it complies with Grade II and conservation-area rules.

Up to 80% noise reduction

A separate internal pane creates an acoustic barrier ideal for homes near busy roads, airports or railways.

Thermal performance

Low-E secondary glazing can match the U-values of many double-glazed units, cutting draughts and heat loss.

Discreet draught-proofing

Brass rollers, brush seals and slim frames preserve the view while sealing the air gaps in single-glazed sashes.

Bespoke for every window

Made-to-measure for arched, bay, sliding-sash and casement windows in timber, steel or Crittall frames.

Installed by heritage specialists

Our team works alongside conservation officers and joiners to ensure the finish is invisible from the street.

Why secondary glazing?

If you own a period property in London, replacing original sash windows with double glazing is often impossible — and usually prohibited within a conservation area or on a listed building. Secondary glazing solves the problem without touching the historic fabric.

A slim, independent pane is fitted to the inside of the existing window, creating an air gap that dramatically cuts heat loss, draughts and outside noise. From the street, the building looks unchanged; inside, rooms become quieter and significantly warmer.

We specify secondary glazing for Kensington, Chelsea, Belgravia and Westminster townhouses where Listed Building Consent and Estate approvals are strict, and where the original glazing must be preserved.
