What makes an Evolution different to most homes?

Our homes are warmer, drier, healthier and a wise investment. We achieve this by using a holistic approach to constructing energy-efficient homes that are extremely comfortable to live in, use fewer resources to run and will stand up to the test of time.  

Our homes benefit from increased insulation, Proclima's vapour check layer (Intello) and exterior wrap (Solitex), superior products, solar energy and clever design.

How much do Evolution homes cost?

The cost of building in Queenstown and in Christchurch fluctuates rapidly that we can give more accurate estimates individually, depending on site location, topography and whether you prefer a bespoke home or one of our nine Inspired Designs.  

For example, building in the exclusive Jack’s Point subdivision includes added costs for consideration of guidelines.

 

Our buying power through Rilean with national suppliers gives us the ability to make the costs of our homes competitive. Then factor in solar power, water heating, 150mm thick walls, increased insulation and high specification windows as standard features and this makes our fixed price quote sound even more competitive.

 

To get a tailored estimate for the type of home you want to build, call Adam (Queenstown) at (03) 442-3484 or Byron (Christchurch) at (03) 377-3484.

Who's behind Evolution?

 

Rilean Construction launched Evolution in 2010 recognizing the need to build better homes suited to the climate.  For more than 20 years, Rilean has demonstrated a commitment to quality, customer satisfaction and sustainability.

 

Rilean has won numerous awards in residential and commercial construction and belongs to the New Zealand Green Building Council (NZGBC). We are a company committed to sustainable practices and construction.

 

 

Are Evolution homes rated by NZGBC  Homestar™?

 

Yes, we compile the documents during construction and submit them to the New Zealand Green Building Council on your behalf.  Our staff includes certified Homestar™ Practitioners, who can give you qualified advice on incorporating high performance features into your design and ideas.

 

A standard Evolution is guaranteed to receive a minimum of 6 stars, which increases the return on the initial investment of building beyond the minimum code.  Homestar™ works on a star rating system 1-10, with a Six Star indicating thermal efficiency, wise water usage and increased comfort while using fewer resources. 

 

 

How energy-efficient are Evolution homes?

We consult with independent building science experts.  Modelling data shows that the homes are 60% more energy-efficient than modern homes built to the minimum New Zealand code. Independent engineers perform a Blower Door Test, recording the air-change-per-hour (ach) that reflect how draft-free, or airtight, the home is.  

 

I see all Evolution homes are made airtight. What is air tightness?

 

Air tightness is required to reduce the amount of air leakage in a home and should not be confused with ventilation. Our homes are sealed with Proclima's Intello, an air tight moisture control membrane, that reduces unwanted air leakage and, with well fitted insulation, reduces power consumption dramatically. We also use Proclima's Extanasa Solitex, a weathertight membrane on the exterior envelope of the house.

For example, a thick jersey in winter works really well until the wind picks up; add a breathable wind breaker and you have ultimate protection and warmth. The same principle applies to our homes.

 

 

Can Evolution homes be adapted to be ‘Passive House’?

Yes, they can.  We work with independent engineers to thermally-test our homes and an Evolution home can be designed and built to work within the principles of Passive House.

 

Can we use our own architect or concept plans?

Yes, absolutely.  Evolution offers a comprehensive method to building an energy-efficient home that can be adapted to any plan or design.

 

Can Evolution homes help with asthma?

The Asthma Foundation has recognised that, amongst other things, mould spores, formaldehyde and cold temperatures in a house could trigger an asthma attack. Our homes minimize the chance of mould, reduce formaldehyde and improve temperature, all of which could assist with the treatment of asthma.

More information on how a well built home contributes to cleaner air and fewer respiratory problems can be found in the article "Spring is in the Air...Can Your Home Help You Breathe Better?"
