Villa Restoration & Renovation

Builders Matakana

RHM Construction completely restored this stunning Auckland Villa back to its former glory.

This Mt. Eden Villa got a complete renovation. Our challenge was to keep the original character of the 1920s property, while giving it some more modern touches.

Six months later, it now has a brand new kitchen and bathroom, a big deck on either side of the property, a fresh coat of paint and to top it off we ditched the carpet for the beautiful original Kauri floorboards.

pricing process

We know that a lot of work goes in to choosing the right builder for your project, so we try to make this process as smooth as possible for you. There are different approaches to price a job, it mostly depends on size and construction requirements, for smaller projects we may be able to give you an estimate of costs involved, when it comes to bigger and more complex projects though we can liaise with our trusted QS and discuss your options from there.

Health and Safety

Practising good H&S in the workplace is our number one priority. We know that an accident of any kind on the job site is bad news for everyone, that is why all of our team is trained to this high standard. Keeping this in mind, we only work with sub-tradesmen that share our view. We are constantly assessing our H&S practices to ensure we are working to WorkSafe NZ standards.
