Working with the team to create a Grand Design

Grand Designs for modern home with Sarnafil flat roofIt’s not every day that your work is featured on a programme that attracts a UK audience of over 4 million viewers with stories of ordinary people designing and constructing homes of their dreams.

But that is exactly what happened when Inner World Design & Build, Bangor was chosen as the main contractor for a new build family home in Criccieth North Wales, to be featured on Channel 4’s Grand Designs. Included in the project was the design and installation of a  Sarnafil single ply flat roof membrane, Sarnatherm roofing insulation,  anchoring bolts into the concrete foundations using Sika AnchorFix-1 polyester resin adhesive and Sika elastic sealing and bonding throughout.

The installation

Kevin McCloud Grand DesignsTechnically the installation was quite demanding as Ian Hunt, managing director, Inner World Design & Build Ltd, explains: “Installing the roofing membrane was quite a challenge on account of the many varying pitches and parapets as well as various penetrations for drains, roof windows, columns etc.  On top of that we had to catch a break in the weather as we were laying the roof during a period of prolonged wet weather”.

The 185m2 roof covered the whole property and a slate grey Sarnafil single ply membrane was applied with adhered baton profiles to re-create the piping of a traditional lead roof.

Behind the dream were Rob Hodgson and his partner Kay, who conceived the highly ambitious plan to design and build this dream house in a wonderful setting on Cardigan Bay, overlooking the sea.  As with many Grand Design projects the location is often the foundation for the design – panoramic views, sometimes a change of lifestyle and a family home with a contemporary aesthetic that is sympathetic to its environment.

A common theme throughout Grand Designs projects is the reluctance to compromise on quality whether it is in workmanship, products or materials.  The attitude is to use the best whatever it takes and whatever the budget. The Sika brand fulfils all those credentials with its Sarnafil single ply roofing membrane being used on high profile projects such as the Emirates Stadium and St Pancras Stadium.

Sika’s structural glazing products were used to seal and secure windows including all the adhesives that hold a pair of enormous windows in place, as well as where the glass meets the natural stone of the perimeter wall. This is from the same range of high quality structural glazing materials which have been used in the Shard and the Gherkin, two iconic London landmarks, so proven to withstand the elements that the coastal weather will throw at it.

Behind the scenes the Grand Designs small production team were unobtrusive, discretely filming around the contractors, while the affable (on and off camera) Kevin McCloud followed the build progress and chatted with owner Rob Hodgson.

Final words from Ian Hunt:  “It was a fantastic project, brilliantly designed and carefully detailed.  It was great working closely with the client, architect, engineer and Building Control as a professional team.  We enjoyed building such a stunning property”.

“The assistance from the Sika technical team along with Simon Roche of SPR Roofing in meeting the challenges posed by this complicated roof was absolutely invaluable. On behalf of ourselves and our client we offer them our gratitude”.

This stunning new home is also being nominated for a LABC North Wales Building Excellence Award. The LABC Awards  recognise not just buildings but celebrate the design and construction teams that have tussled with technical issues, difficult sites and found innovative and creative solutions.
