New homes and renovations

Most of our work is new homes, from family homes in town to architect-designed houses on rural sections. We also do renovations, extensions and smaller jobs.

Your new home, in good hands

Building a new home is one of the most exciting things you'll do, and we want you to enjoy every step of it. Kieran grew up in the Wairarapa and has been building here for more than 20 years, with a small, close-knit team based in Greytown.

He's with you from the first site visit and pricing right through to handover, so you'll always have someone who knows your home inside out and is easy to reach.

We work across the Wairarapa, including Greytown, Featherston, Martinborough, Carterton and Masterton.

Kieran and his team completed a full renovation / rebuild of an historic cottage for us. Kieran and his team were always helpful, polite, on time and available to chat about any questions or variations we wanted to discuss.

Kieran did an amazing job. He coordinated the different trades very efficiently. He was also extremely precise with great attention to detail as it was a tight space with no room for error. He was very easy to work with and did things in a timely manner. I cannot recommend him more highly.

Not only did Kieran deliver on time and to budget he really helped in the design process, with suggestions that led to a better outcome… It's my third build in NZ and far and away the best experience by miles.

Common questions

Can't see your question here? Give Kieran a call on 027 518 8876.

Do you do smaller jobs?

Yes. Alongside new homes, we look after bathrooms, kitchens, laundries, decks, extensions and repairs, all done by the same team. Have a look at our renovation work.

When should I talk to a builder?

Earlier than most people think. Having a chat before you buy a section or finalise your plans can save time and money later on, and Kieran is always happy to talk things through, whatever stage you're at. Our free guide covers this in more detail.

Can you build from my architect's plans?

Absolutely. We work with a number of architects and designers around the Wairarapa, and if you're starting from scratch we can help you find the right one. Read more about building a new home with us.

How long does a new build take?

Most homes take between 6 and 12 months from breaking ground to handover, depending on the size of the build and the weather. Building consent usually adds 4 to 8 weeks beforehand.

Which areas do you cover?

We're based in Greytown and build right across the Wairarapa, from Featherston and Martinborough to Carterton, Masterton and the rural areas in between. We also build on the coast, from Riversdale and Castlepoint down to the South Wairarapa coast.
