Modern glass box extension to Grade II Listed Warwickshire house

Hayward Smart was the appointed practice to transform a mid 17th Century period stone house with a highly transparent, and modern frameless glass box extension 

Situated in the quaint village of Honington within a conservation area, Warwickshire, this Grade II Listed house covering 2,400 square feet required significant updating to the north facing 1970’s lean-to adjacent to the kitchen which looks out over the garden.

Warwickshire

The rear of the Grade II listed Warwickshire house had endured some unsightly extensions over the years. The new minimal glass box extension with modern innovative architectural elements would allo great light to enter this north facing extension.

To pass planning the glass box extension needed to be as transparent and frameless as possible to express the historic elevation, which is why Hayward Smart commissioned IQ Glass to deliver.  

The new single storey side extension to this listed Warwicks property required an even dispersion of natural light to make it work as a bright and functional spaceA bespoke structural glass extension was created using a frameless silicon bonded Invisio slim strip rooflight and slim sliding glass doors to create a bright airy space with seamless transitions to the garden.  

The Invisio frameless glass strip rooflight spans just under 8m across the new glazed extension to this Grade II listed Warwickshire home consisting of four fixed panels each weighing 133kg silicone bonded for the ultimate minimal finish offering uninterrupted views of the sky whilst allowing balanced natural light to flood into the internal space. The strip rooflight uses 8mm toughened glass.  

Large expanses of full-height slim sliding glass doors wrap around the single storey kitchen and dining extension, offering direct access to the outdoors and framing views out over the garden with minimal sightlines of 21mm.

As well as ensuring the historic stonework of the rear wall of the property was highly visible from inside and out, the bi parting slim framed sliding glass doors are globally aligned with the structural beams of the pavilion style rear extension. The original timber beam in the ceiling was retained, exposing more of this property’s character.  

Flush thresholds of the slim sliding glass doors make for an inclusive design for seamless transitions between the kitchen dining space and the patio.  

The flat timber cladding to the underpart of the overhanging roof extends to the traditional timber door providing sheltered access.  The overhang of the roof also offers some protection from excessive solar gain.

The result is triumphant with the occupants of this Grade II listed Warwickshire house enjoying the newly reconfigured spaces, especially the contemporary glass box extension housing the kitchen and dining space, often regarded as the beating heart of the home.  

The architects achieved a design that offers form and functionality delivering on preserving and enhancing the setting through well considered design.
