Accoya Sash Windows – Chesterton Road

Bespoke accoya windows and conservatory, Chesterton Road London

Our assistance in this extensive refurbishment proved to be invaluable as we overcame structural and aesthetic problems. This challenging project highlighted Gowercroft's passion and professional expertise to the new owners, who were very happy with the building process and the finished product.

Accoya Sash Windows and conservatory were the perfect way to add space and light to this badly neglected Kensington town house. The highly bespoke nature of the project meant that the Gowercroft team were able to assist with the structural effects that windows and extensions have on properties.

Accoya Sliding Sash Windows were the starting point…

The new owners Mark and Alexis Burton had a very strong vision for their renovation project – central to their idea were the style of windows they wanted. They were looking for a traditional look, but were aware that the installation needed to be very secure, and ideally highly efficient.

After meeting the couple at the Home Building and Renovation Show at the Birmingham NEC, we were commissioned to install our Chatsworth Sliding Sash windows and a bespoke lean-to conservatory. The plan was to extend the house as much as the limited space in the grounds would allow, whilst maintaining the traditional look and feel of the property.

Structural Issues prior to commencement

Before any work could commence, several structural issues with the property needed to be addressed. At the initial site meeting, it was clear that subsidence had altered the overall structure of the building, and that work would be required to stabilise the property. Once this was completed, there was a need to alter some of the window openings and replace external render to ensure that the sightlines on the windows of the property were clean and aligned. David, our Technical Director, worked closely with Mark and Alexis to draw up a schedule of window sizes that would require the least building work but give the most balanced appearance.

I met Gowercroft at a trade show just as we were starting work on our house, which we had bought in a state of disrepair. David came to visit the house and I immediately knew I wanted them to be involved in the renovation project that lay ahead.

Bespoke Accoya Hardwood conservatory

David worked to design a bespoke conservatory around the desired vision and the limited space available at the side of the house. It was important to Mark and Alexis that it would provide a secure and well lit extension to the existing living space; as such, the conservatory was designed to fit between the exterior wall of the property and a newly constructed brick wall on the edge of the adjoining property. This presented problems in terms of guttering and raising the apex to the necessary height without impeding on building regulations. These issues were overcome through the use a structural gutter, allowing weight to be distributed to the new brick wall – all of the design was done collaboratively to ensure that it was structurally sound and met Mark and Alexis’ vision for the house.

Gowercroft are a rare kind of business who have combined true passion for their product and its execution, with a personal touch so often lacking in the building trade. Our new sash windows and bespoke conservatory are of the highest quality and finish, and went in on time with no fuss. I would highly recommend them.

Why we use Accoya for our Windows and Doors

We use Accoya in the manufacture of our windows and doors because it has outstanding durability and stability. It has a 70 year minimum service life (stated by TRADA). It’s improved stability over other timbers means that doors and windows open effortlessly year round. Also, with this reduced swelling and shrinkage, any coatings will last up to two times longer. With it’s enhanced lifespan and reduced maintenance, the environmental impact from using Accoya is greatly reduced.
