Grade ll listed House in Oxfordshire

Project: Grade ll listed House in Oxfordshire

Nestling in the beautiful Oxfordshire countryside, sections of this magnificent three-storey Grade II* Listed building date back to the 16th century. Amongst the many outstanding features are two imposing Tudor fireplaces and a beautifully preserved 1614 Jacobean staircase. The main part of the building, however, is 18th century and features long wide halls traversing each floor, helping to create a house of majestic proportion. The landscaped grounds are enclosed by an equally impressive Grade II* listed wall featuring a number of late medieval Gothic windows and an original window from Brasenose College’s chapel of the same period.

In recent years the property has featured in episodes of TV’s “Midsomer Murders” and “Amazing Grace” (a biographical drama film about the campaign against slave trade in the British Empire, led by William Wilberforce).

The house, its grounds and numerous outbuildings including extensive stabling, has been a family home for the past 42 years. With spiralling fuel costs, the owners felt the time had come to investigate ways of providing a warm and draught free home, particularly for when their young grandchildren visit. Serious consideration was, therefore, given to thermally insulating the windows.

The owners, as members of the Historic Houses Association, frequently attend Association sponsored conferences. “It was here we met Energy Consultant Jonathan Clarke, one of that day’s speakers. Following the conference we engaged Mr. Clarke to produce recommendations on our behalf. The resulting report included particular reference to Selectaglaze’s secondary glazing systems and their experience working with listed buildings. And, of course, secondary glazing is an option approved by English Heritage. Initially, we had the windows on the ground floor treated and immediately realised what a difference secondary glazing made to our comfort. They are also very unobtrusive and beautifully tailor-made, so we decided to do the top floors as well”.

A total of forty-seven sash and casement windows needed to be treated, many with existing wooden shutters which were to be retained. It was also essential that the windows remained fully operational to facilitate cleaning and maintenance, without introducing additional sightlines. To accommodate this exacting brief Selectaglaze recommended a number of styles including their very slim sectioned Series 47 Hinged Casements - a range designed specifically for “heritage” buildings – together with their Series 20 Slimline Vertical Sliding units.

Several rooms feature 17th and 18th century oak and ash panelling with window frames painted to match. To blend imperceptibly with this internal décor, Selectaglaze supplied secondary glazing finished in a brown Polyester Powder paint.


All units were glazed with 4mm toughened low emissivity glass to provide the very best thermal insulation
