What they have to say about us

Upon completion of extensive research and a rather poor experience with a Queensland based company that saw me out of pocket, I decided to move to a proven professional product that certainly is world renowned as a leader in EPS ICF construction. I have found Quad-Lock ICF has superior thermal and sound properties than its competitors and has been in existence for 30 years globally. It therefore comes with extensive training and support from its training library which is provided for free. From a product use perspective, it is simple to use and cheaper when compared to bricks as less labour is used and time used to construct is quicker.

Housekonsept has provided excellent, prompt, friendly customer support for all my ongoing needs such as transportation, logistics, external storage, site supervisions and answered any questions that I had including training installers. It has been an enjoyable experience and a very professional throughout. I am happy to recommend Housekonsept as a company and certainly Quadlock.

I have designed a range of project homes for HouseKonsept, a new start-up home building company based in Sydney, NSW.

They had chosen Quad-Lock as their preferred method of construction because of its superior environmental, thermal and acoustic characteristics, its inherent strength, its ease and economy of construction.

I found it very easy to design with due to the inherent flexibility of the system, offering no impediments to creative yet economical design solutions.

A variety of external finishes are available ranging between rendered finishes, fibre cement and timber cladding, and brick and stone veneers.

The range of homes designed consisted of single and double-storey homes ranging from simple first home buyer’s models through to large high-end luxury homes.

As an environmentally sustainable economic and flexible construction system, I believe it is a breakthrough system in residential construction and is set to revolutionise the home building industry in Australia

We Have Been Really, Really Impressed With The Quad-Lock ICF System So Far. The Quality Of The Materials Is Very Good – The Tolerances Are Spot On, The Keys Don’t Break Off, The Ties Are Strong, Etc. It All Just Goes Together Really Easily And Is Nice And Strong. I Did A Lot Of Research Across Dozens Of Different Systems Before Choosing Quad-Lock And I Am Really Glad That We Chose This System.

I met Yaron & the Housekonsept team a few years ago, and I am happy to recommend their service and the Quad-Lock product to anyone who is looking to build their house, a builder or developer.  
I found that Quad-Lock R-value, the noise insulation, and the cost savings with easy and assemble is significantly better than commonly used products I’ve used in the marketplace.

I have been working with Quad-lock products on numerous projects in Australia and overseas for the last 3 years. The Quad-lock system is one of the most innovative concrete building solutions that I have encountered in my career life. In my opinion, the system is simple to design and assemble on site. The material of the system has been designed to various safety and durability standards in Australia and Internationally. Overall, I believe Quad-lock is a great product that brings simplicity, efficiency, safety and durability to our building industry.

Building with ICF was very exciting. Very easy to use as it’s self explanatory. I would definitely recommend to further home owners.
