Twin Gables, Hanley

ARCHITECTS for the new-build replacement of an obsolete 1930s house in the leafy Hertfordshire suburb of Hanley specified a substantial rendered element for the exterior of the property designed to echo the charms of the Cotswold “stone” manor houses of “Cider with Rosie” country.

The 12,000 square foot four-storey property, recently completed, was designed by Lees Munday Architects, of Guildford, for clients, owner and main contractor Optic Realm, Ltd, of Islington, London.

Twin Gables is a luxury seven-bedroom residence encompassing a large swimming pool and leisure suite, sauna and steam rooms, cinema room, wine cellar, extensive living and entertaining spaces.

In addition to its stylish Cotswold stone piers, the property also features simple white rendered forms influenced by Hugh Newell Jacobson, the pre-eminent American residential architect. This is particularly evident where rendered sections have been taken “over the top” without the addition of copings.

Comments architect David Lees: “The pillared two-storey bays and double height entrance façade combining Cotswold stone and white render creates a grand impression down a discrete private driveway approach, passing through four small landscaped ‘external rooms’, each containing a gigantic antique cast iron urn.”

Specialist rendering contractors EnviroREND SE Ltd applied a combination of Parex renders following consultation and advice from the Parex technical team.

The main building features a base coat of water-repellent and breathable Parex Pamurex applied directly to the blockwork with Parex TV10 Mesh embedded throughout to improve strength and durability.

The top coat render system was applied, commencing with the Parex DPR Primer, which was then coated with Parex DPR Sand Coarse applied as a dragged effect in a Pure White (RAL9010) colour to complement the contemporary design of the building. The rear of the property also featured rendered sections to a more delicate timber-framed bay and garden room where an external grade render board received a coat of high performance Parex Maite, embedded with Parex 355 AVU mesh. This was then coated with the same top coat render system and matching dragged effect finish.

All the rendered areas were then treated with Parex Paraguard breathable protective coating which helped to keep the render in pristine condition during a further 12 months’ of dusty site work following rendering.

Adds David Lees: “A major differentiator for choosing Parex was the fast, expert and highly knowledgeable advice, bringing in experts from around the company as necessary.”
