Clover House, Kingston Hill. Surrey

Project: Clover House, Kingston Hill. Surrey

Clover House, a 1960’s architect-designed home, is benefiting from the rewards of Warm Wall by Knauf Marmorit to externally insulate its new extension as part of the re-modelling and re-arrangement of the house to provide for the needs of a growing family.

The prestigious house located at the top of Kingston Hill, Surrey, is a 200m² building. The project was for a new two-storey extension located at the front of the building, accommodating a new kitchen/dining space and utility room on the ground floor and a master bedroom suite above. At the rear of the building a new first floor bedroom was added over the existing living room.

Knauf’s Warm Wall Basis system with contrasting coloured silicon render was used for Clover House to externally insulate and to relate to the existing changes in materials between the ground floor and the timber cladding on the first floor.

Warm Wall is the simplest and easiest way to thermally upgrade a building. The Warm Wall Basis system is an economic standard solution that can significantly reduce energy costs and heat loss for a building through the external façade, in a cost-effective and innovative way.

Knauf Marmorit accredited specialist render subcontractor, EWS Residential, recommended the Warm Wall system to richard pain architect, with Richard Pain commenting, “The quality of the surface is excellent - even with the low angled sun of mid November the surface shows no sign of ripple or joint. The colour is even and the 1.5mm aggregate has provided a long-distance smooth surface and a close-up surface of character.”

Richard Pain RIBA is an architect with over 30 years of professional experience and has worked with Knauf Marmorit on previous projects.

He continued, “The benefits of keeping a structure warm in the winter and cool in the summer have long been understood by Knauf Marmorit. With no redundant cavity space or brick outer skin the wall can work much more efficiently in the same overall wall thickness.”

The project was completed with the silicon based render finish, Conni S, as a water repellent vapour permeable long term protection against driving rain, resistant to algae and fungi, and has an impact resistant surface. A dark grey render is used on the ground floor walls and a white render for the first floor walls.

Warm Wall comes with a superior range of associated components, render finishes and colours to ensure that whilst the focus is on producing energy-efficient dwellings for the future, the ability to use the creativity in designing contemporary or traditional buildings is not lost through technical advancement.
