Westminster Areas We Serve
Comprehensive coverage across all Westminster neighborhoods
Thomas Cubitt's 1840s stucco terraces around Warwick Square, Eccleston Square, and St George's Square form one of London's finest early Victorian planned estates. The Dolphin Square residential complex (1937) houses over 1,200 apartments with original Crittall windows. Our secondary glazing retrofits to both the Cubitt terraces and Dolphin Square's metal-framed windows, solving the persistent Vauxhall Bridge Road traffic noise that residents report as their primary complaint.
Key streets: Warwick Square, Eccleston Square, St George's Drive, Lupus Street, Cambridge Street
St James's Palace, Carlton House Terrace (John Nash, 1827), and the Crown Estate properties along Pall Mall represent some of England's most architecturally significant buildings. The Crown Estate's property management team requires detailed heritage impact assessments before approving any works. We've completed installations in Crown Estate apartments on Carlton House Terrace, where our secondary glazing blocks the noise from The Mall's ceremonial traffic while preserving Nash's irreplaceable window proportions.
Key streets: Pall Mall, St James's Street, King Street, Jermyn Street, Carlton House Terrace
The grand Victorian terraces along Sussex Gardens, Westbourne Terrace, and Cleveland Square (c.1850-1870) were originally built as premium London residences. Many are now subdivided into flats where noise from the Paddington railway approaches and Bayswater Road (A402) makes street-facing rooms challenging. Our acoustic secondary glazing has been installed in over 30 Bayswater properties, with the most dramatic results in Sussex Gardens apartments facing the Heathrow Express tracks.
Key streets: Sussex Gardens, Westbourne Terrace, Cleveland Square, Craven Hill, Porchester Square
