Villas, additions and big renovations across South Auckland and North Waikato.
We specialise in large renovations and extensions, including projects that need special care and technical knowledge, like villa renovations. Working inside an existing structure is often harder than building new, so choose a builder who has done it many times.
Not sure where to start? Tell us what you would like to achieve and we will talk it through with you. Many of our renovation clients come back for their next home or an investment property.



Sizes range from an ensuite to a full house rebuild.
Whole house renovations that change how a home works for your family.
Careful work on older homes, keeping the character and fixing what's behind the walls.
More room for a growing family, built to match the house you have.
Leaking ensuite? We check, quote and manage every trade on site.
Weathertightness repairs with specialist engineers, for people let down by poor workmanship in the past.
From a family deck to a big deck and retaining wall on a cliff above the Manukau Harbour.
Write two lists and talk them through with us. A good builder can help you get more of both for your money.
For a big renovation, budget for other accommodation while the work is done.
Every project needs a buffer for surprises, like hidden rot in a wall that nobody could see before.
As NZ Certified Builders members we can offer one of the most complete 10 year guarantees on the market. It is run independently, and it moves to the new owner if you sell within 10 years.
Another important difference with Heineke Builders has been their after sales service, which has been nothing short of excellent.
The completed project brought the home back to a better than original condition.
The new cladding, bathroom, exterior stairs etc look magnificent. If ever we need another job doing, Heineke Builders Ltd are first on our list.
Charge up means you pay for the actual time and materials, but the final price is unknown. A fixed price gives you more certainty up front. In a renovation some items still can’t be priced until the walls are open, so we mark those clearly in the quote.
Most building work needs a building consent. Tell us what you are planning and we will tell you whether your renovation needs one or could be exempt.
That depends on the size of the job. For a big renovation, plan and budget for somewhere else to live while the work is done. On some projects owners do stay: during one cladding repair the owners lived in the house the whole time.
We price any change in scope or materials before we start on it, whether you ask for it or it turns out to be necessary. That way you know what it costs and there are no surprises.
