Introduction
Building a custom home allows homeowners to tailor every aspect of the house to their specific needs and preferences, from layout and materials to finishes and landscaping. Custom homes can also offer the opportunity to choose the latest technologies and design trends, ensuring the house remains modern and functional for years to come.
This blog provides a detailed guide on the stages of building a house in New Zealand, offering practical insights and advice for prospective homeowners.
Land Selection and Purchase
Factors to Consider When Selecting Land
Selecting the right piece of land is crucial. Key factors include:
- Location: Proximity to amenities, schools (grammar zone), hospital; neighbourhood safety and future development plans.
- Geological Conditions: Soil type, risk of hazards like flooding and slippage (slope stability).
- Legal Requirements: Zoning regulations, easements, covenant and any restrictions on land use.
Land Survey and Acquisition Process
A professional land survey ensures the property boundaries are accurate and identifies any potential issues, such as encroachments or rights of way. The acquisition process involves negotiating with the seller, securing financing, and completing the legal transfer of ownership through a solicitor.
Design and Planning
Collaborating with Architects or Designers
Clearly outline your needs, preferences, and financial constraints. Prioritise essential features and be prepared to make trade-offs to stay within budget. Engaging an architect or designer early to translate your vision into a workable plan. They will help navigate regulatory requirements. Regular meetings and clear communication are crucial to ensure the design meets all expectations and complies with local building codes. It is good idea to seek for advice from builders who specialise in design and build so that they can help you stay in the budget before going to the detail design reducing design iterations.
Check RC requirements
Resource Consents are issued under the Resource Management Act and the District Plan. The Act is the overarching legislation under which each local authority must prepare its District Plan, resulting in variations across the country. Generally, you won’t require a Resource Consent for a new building unless you are in a specific zone or have a particular feature that mandates it. However, if you infringe upon any rules in the District Plan, you will need to obtain a Resource Consent. The Land Information Memorandum (LIM) you prudently obtained when purchasing the property would provide these details.
Obtaining Building Consent
Comparing to Resource Consents, Building Consents are issued under the Building Act and are generally required for almost any residential construction project. The Building Act is national legislation, although there may be some regional variations, these differences are typically minimal.
Required Documents and Drawings Typical submissions include:
- Architectural drawings.
- Specifications for materials and construction methods.
- Structural/Civil drawings and calculation.
- Geotechnical report.
- Energy efficiency calculations.
Approval Process and Potential Modifications
The council reviews the application for compliance with the Building Code. They may request modifications or additional information before granting consent. The approval process can take several weeks to months, depending on the complexity of the project.
Construction of the Building Structure
Clearing and Preparing the Land
Clear the site of vegetation, debris, and any existing structures. Level the ground and ensure proper drainage. Erosion control measures may be required to prevent sediment runoff during construction. Moreover, establish temporary power and water supply for construction purposes. Secure the site with fencing to prevent unauthorised access and ensure safety. Excavate the site according to the foundation design, lay formwork, and pour concrete to create a stable base for the structure. Proper foundation construction is critical to the structural integrity of the house.
Structural Framing and Roofing
Construct the building’s framework using timber or steel, depending on the design and structural requirements. This stage includes erecting load-bearing walls, beams, and floor joists. Next, install the roof structure to provide weather protection and structural integrity.
Window, Door, and Cladding Installation
Fit windows and doors to enclose the building and ensure security and weatherproofing. Then, install exterior cladding to protect the building from the elements and provide insulation.
Plumbing and Electrical Systems
Install plumbing systems for water, waste, and gas, ensuring compliance with New Zealand Building Standards. Conduct electrical installations to meet safety and functionality requirements. Proper installation of these systems is crucial for the house’s functionality and safety.
Building Inspections and Compliance Checks
Regular inspections by council inspectors ensure that the construction meets Building Code requirements at each critical stage. These inspections cover foundations, framing, plumbing, electrical work, and final finishes.
Interior Finishing
Insulation and Drywall Installation
Install insulation to meet energy efficiency requirements and fit drywall to create internal walls and ceilings. Proper insulation improves energy efficiency and comfort within the home.
Interior Plastering and Painting
Apply plaster to interior walls and ceilings, followed by paint, ensuring proper preparation and finishing techniques. Use quality paints and finishes to ensure durability and aesthetic appeal.
Interior Waterproofing and Tiling
Ensure that all wet areas, such as bathrooms, have adequate waterproofing to prevent water damage. Lay tiles on floors and walls in these areas, ensuring durability and ease of maintenance.
Installing Cabinets and Final Fixtures
Install kitchen cabinetry, countertops, and bathroom fixtures, ensuring all installations meet quality standards. Perform the final plumbing and electrical work, ensuring all systems are functioning correctly and safely.
Final Touches and Floor Coverings
Complete any remaining painting and finishing work to enhance the home’s functionality and appearance. Lay floor coverings to complete the interior finish of the home.
Final Inspection and Touch-ups
Conduct a final, thorough inspection of all aspects of the building to identify any defects or areas requiring touch-ups, ensuring all work meets the required standards and specifications. Promptly address any issues identified during this inspection to maintain the quality and safety of the home. Obtain the Code Compliance Certificate (CCC) from the local council, confirming that all work complies with the Building Code, which is essential for legally occupying the house.
Once compliance is secured, perform a thorough cleaning of the site, removing all construction debris and organising it for occupancy. Prepare the house for moving in by setting up utilities and arranging furniture, ensuring all systems (plumbing, electrical, heating) are operational and functional.
