A pleasant view or attractive asking price does not establish suitability for building. Gather legal and physical information separately, then consider their combined effect on design and budget. Prefabrication does not automatically remove difficult ground conditions or the need for infrastructure.
Planning and permissions are parcel-specific
Ask for current information about permitted use, development conditions, boundaries and the responsible authority. Being beside a road or near existing homes is not sufficient evidence. The Ministry’s e-Plan system provides access to planning information, but a screenshot does not confirm all permissions for your particular parcel. Clarify agricultural, conservation or other special conditions in writing with the authority and design team.
Ground conditions and topography are different
Slope, levels and rainwater movement influence the layout. Ground bearing and deformation behaviour require appropriate investigation and engineering assessment. A flat-looking plot is not proof of suitable ground. Fill, retaining work, drainage or foundation requirements may change overall cost. Do not select foundation dimensions from a catalogue model; request a design based on building loads and site information.
A road is not proof of delivery access
Narrow turns, height restrictions, bridges, gradients and surfaces along the full route matter as well as the final approach. Transporting panels and transporting volumetric modules may have different requirements. The haulier and assembly team should review the delivery plan. Share entrance photographs, location and known obstructions. If neighbouring land or temporary storage is needed, access rights and arrangements must be established separately.
Plan lifting and site operations deliberately
Whether lifting equipment is required, where it can operate and which ground conditions it needs must be established by the specialist team for the equipment and loads involved. A homeowner’s sketch is not a lifting plan. Power lines, neighbouring structures, pedestrian routes and temporary storage belong in site planning. A catalogue delivery photograph does not guarantee that the same method will suit your land.
Position the building with utilities and surroundings
Establish the location, capacity, permissions and responsibilities for power, water, wastewater and communications. A nearby service line does not establish a ready connection. Consider sun, wind, privacy, entrance, parking and outdoor use together. Rainwater management should protect the building without creating problems for neighbouring land, with the solution designed by the appropriate team. Track site and connection works separately from the building price.
Your site review file
- Parcel identity and current authority/planning information.
- Responsibility for ground and level investigations.
- Route and entrance photographs.
- Delivery, lifting and temporary-space review.
- Connection conditions from utility providers.
- A separate scope and budget for site works.
