James Hardie Delivers Multi-Clad Appeal for St Kilda Homes

The quarter acre dream is still within reach at the St Kilda subdivision in Cambridge. In this newly developed subdivision, an average section is 1,600m², which is twice the size of today's average suburban sections for sale in Hamilton and Cambridge.

The high spec two-storey Wetlands Duplex showhome features James Hardie Linea Weatherboard and Stria Cladding on the exterior, with Secura Interior Flooring on the upper floor. The materials were selected for their superior quality, with the cladding providing an 'upmarket and high-end' feel.

The Challenge

The requirement was architecturally designed homes that allow easy and comfortable modern day living on large sections — without breaking the bank — and without compromise.

With a starting price of just $270,000, these homes are built using quality materials to deliver value-for-money that is difficult to find elsewhere in New Zealand.

The James Hardie Solution

"We didn't want to compromise on the claddings and fixtures," says Aaron Guerin, Director of LAD Architecture. "Linea Weatherboard and Stria Cladding are showcase products and possess unique features that complement the cedar panelling also used on the home's exterior."

James Hardie products work well together and with other products to provide maximum design flexibility, as evidenced in this home. Linea Weatherboard was installed as the predominant cladding, with Stria Cladding used on the lower floor as a striking feature. The broad, clean lines of Stria create a bold and dynamic finish, making it ideal for this contemporary design home. The claddings are painted in a modern dark grey colour scheme.

In addition to design flexibility, James Hardie claddings provide build benefits. The lightweight cement composite sheets are gun nailable and easy to work with.

"The builders can lift and fix the sheets quickly and easily, providing significant benefits labour-wise," explains Guerin. These benefits are passed onto the homeowner and are reflected in the affordability of these homes.

During construction James Hardie reps were on hand to provide support to the build. Reps also provided installation training prior to works commencing, which Guerin says will help ensure the home meets the expectations of customers and Synergy Designer Homes' own high standards.

The flooring for the upstairs master bedroom also provided building efficiencies.

Secura Interior Flooring is an all-in-one product — it can be tiled directly without the need for underlay, saving further time and money on the build.

The moisture-resistant sealer is an easy way to protect against moisture damage to interior floors. Guerin says, "The waterproofing element has provided us with security during the build and it provides long-term benefits in terms of its durability."

Its durable construction gives a squeak-free, solid feel under carpet, tiles or vinyl. The acoustic properties of the flooring, coupled with its stability and rigidity, are ideal for this high spec home.

"We pride ourselves on design, detail, and finish — and James Hardie's products fit the brief well," says Guerin.
