GRAY BACH: ENGINEERING ON THE EDGE

graybach_4projresAnn and Noel Gray engaged Studio Pacific Architecture to design a Kiwi Bach at Cape Palliser, located on what could be one of the most exposed house sites in the country. After discussions with the architects and engineering firm, Dunning Thornton, the Grays chose Latteys to manufacture and erect the precast panels that form both internal and external walls. The external panels are Insulated sandwich panels incorporating extruded Styrofoam and fibreglass ties with galvanised mesh in the external cladding layer and a 150mm thick structural internal layer.
This gives the external walls an R-value of 1.70 plus the benefits of thermal mass.

In addition, many of the panels were unusual shapes with the one end wall leaning 15 degrees off vertical. Outwards! The plumbing and electrical pipes and fittings were cast into the panels in the factory minimising subcontractor time
and travel to site.

On completion the Gray’s were impressed with the solid feel and low noise of the bach when Antarctica via Cook Strait is throwing it’s worst at it, the minimal heat requirements in the winter and relative coolness in summer.

Here’s what Ann and Noel Gray had to say about their contemporary coastal home and Latteys:

The bach has far exceeded our expectations of looks, liveability and finish. Latteys were totally professional throughout the design and build process. The quality of their work is of an extremely high standard and we were very satisfied that the job was completed on time. We are currently designing a new family home with Latteys’ help and are looking forward to working with them again. We would have no hesitation in recommending Lattey Civil Engineers to others.
