When fixing a house suffering from leaky house syndrome, there are some high level considerations that must be made. On my rebuild project this includes:
- Rebuild or Repair
- Joinery Options
- Cladding Options
- Roof Design and Materials
Rebuild or Repair
Is it worth repairing the house or should I rebuild a completely new home? With such stigma attached to repaired leaky houses, it is worth investigating with local real estate agents the financial impact of the stigma attached to leaky homes.
A rough calculation to rebuild the house from scratch is around $320,000. This does not include demolition of the existing house, or factor in any parts that are reusable. Reusable items include the floor, any unaffected structural elements, joinery, bathroom fittings etc. Even should I replace all joinery, it may be more cost effective to reuse the glass in the existing joinery, if it meets thermal requirements.
If the design of the house is not really to your liking, rebuilding is a great option. Unfortunately, my house is a great design for the site, so there will be virtually no design changes in rebuilding to take advantage of. However, even a few minor changes in kitchens and bathrooms, and changing the size and location of windows can make a big impact to the living enjoyment of the home.
Estimates to rebuild are in the range of $180,000 – $250,000 so one has to consider if the additional investment is worth while. With such a wide range, this is a tough decision. At $180,000 I would repair, at $250,000 I will rebuild. So this is a decision that really can only be made once the final costs are confirmed – and that may not be until they start demolition. Hence, my current view is that since the building of a new home will be almost identical in design to a repaired home, and any differences can be incorporated into a repaired home with minimal extra cost, I will design for a total rebuild and then start cutting the cost back once we ascertain what parts are reusable.
Building Acts and Trade Licensing
The Building Act in NZ was updated in 2004. This new Act includes provisions specifically to improve weather tightness and also incorporates energy efficiency items such as insulation specifications for wall, roofs and windows.
With the climatic changes in NZ over the past 5 years, we are experiencing more extreme conditions. The summers are hotter in the northern regions and the winters colder in the southern regions.
Another consideration is with trade licensing. This will provide some form of checking option for consumers that their tradesmen are qualified. From November 2007, design and building practitioners will be able to start applying to be licensed under the government’s licensed building practitioner scheme. A public register will be able online.
In addition, consumers will be able to make complaints to the Building Practitioners Board about licensed building practitioners if they carry out substandard work. Not every builder will have to have a license but at least you have the option of knowing who has and who has not.
In my case, building will hopefully start around the time this comes into effect, so I will not be able to take advantage of pre-checking, but it does give me more options if I have a problem with the builder and subs.
