Hallo / Hello

​Welcome to Öko Konstrukt. We specialise in the construction of high performance homes, certified to PassivHaus and/or Homestar in the greater Auckland area. We can take your project from concept through to completion, or convert existing plans suitable for PassivHaus construction. The combination of PassivHaus and Homestar will ensure that your project ends up being the most comfortable, most efficient home you have ever lived in.

PassivHaus

​​PassivHaus design and modelling allows us to accurately predict the superior performance of your home when commissioned, then provide you assurance through rigorous third party verification. It will provide a healthy and comfortable living environment for you and your family, at the same time as reducing your primary energy load by as much as 80%. Then you can consider adding local power generation like PV. Plus there are the long term benefits of building structures that will last generations, guaranteeing no internal condensation and reducing C02 output over the lifetime of the building which assists in the reduction of global warming. Housing is one of the most significant impacts on carbon emissions. It also allows you to enjoy the added benefits of living in a quiet, secure home - appropriate for all types of construction. Stand alone homes, town houses, or sprawling rural residences.

​It is the standard that every home in New Zealand should be built to. We're just getting a head start.

Homestar

While PassivHaus focusses on thermal and energy modelling and design, Homestar allows us to work with you on considering a much wider range of decisions when building. Homestar is developed here in New Zealand by the New Zealand Green Building Council and focusses on important areas of sustainable building such as waste, water usage, material choice, innovation and more. PassivHaus certified homes automatically qualify for the energy performance criteria of Homestar which means the two verification tools integrate and are complementary to each other.

Office & Show Home

The main office for Öko Konstrukt is based in a PassivHaus Plus certified, 10 Homestar rated dwelling, "The Ideal House". This was a project that we project managed from inception through to completion in 2014. It is also a Positive Energy home producing substantially more energy than it consumes through an 8kW photovoltaic installation. It has been monitored over two years by the University of Auckland, confirming the performance of the home both in temperature and humidity and has been featured in a wide range of industry publications. The home can maintain 20 degrees all year with no external heating sources, and sits around 20-30% below outside relative humidity ensuring superb indoor air quality.

Öko Konstrukt Management

The management team of Öko Konstrukt​ consist of Murray Durbin & Toby Tilsley.

Murray has been involved with PassivHaus since assisting with the first PassivHaus in Australasia, "PH1NZ", in Glendowie in 2012. He was a founding Trustee of the Passive House Institute of New Zealand (PHINZ). He has held senior national procurement positions at both Mitre10 and Carters head offices, before developing and launching Mammoth Insulation, followed by Knauf Insulation (Earthwool glasswool) in the New Zealand market. He is the owner of The Ideal House, a PassivHaus Plus, 10 Homestar built rated project. Murray is also the Managing Director of Enveloped Systems Limited, a business specialising in the supply and installation of systems for high performance homes.

Toby is also the co-owner of Craft Homes, an established building company in Auckland specialising in high quality, environmentally conscious homes. Toby brings years of hands on building experience and project management, a raft of positive referrals from customers, as well as a large team of carpenters and reliable sub-contractors. Toby is a trained Homestar practitioner and a Certified Builder. The creation of the Öko Konstrukt brand allows the separation between certified PassivHaus, and non-certified projects to ensure absolute commitment to the company's objectives.

Preferred construction systems

If you chose to build in timber, we recommend a double layer wall system (140mm external frame with a 50mm internal service cavity), with a rigid air-barrier, intello air-tightness membranes, and a fully insulated concrete slab.

If you like the strength, durability and acoustic benefits of concrete, Öko Konstrukt are authorised installers of Izodom ICF concrete formwork from Europe, as well as utilising the services of sister company Enveloped to supply and install the full range of pro clima air and weather tightness products, Zehndher balanced heat transfer ventilation, GreenE heat pump hot water cylinders, Bionic low emission fires, Earthwool glasswool, and PIRmax HR panels, amongst other high technology products.

Solid construction dwellings are perfect for meeting Council fire regulations and inter-tenancy sound ratings. There is nothing like the quality of a solid concrete house which can be built with no thermal bridges. Öko Konstrukt can also supply and install Izodom for your own projects, and we will work with you to convert your plans to suit Izodom ICF construction and then offer a turnkey solution ready to ft your windows and doors allowing you to move quickly onto your interior fitout - and worry about the cladding later. The earlier we can get involved the better.
