Planning & Design

How long does the design phase take?

The design phase typically takes 4-8 weeks for residential projects and 8-16 weeks for commercial projects. This includes:

  • Initial concept design (1-2 weeks)
  • Detailed design development (2-4 weeks)
  • Construction documentation (2-4 weeks)
  • Council submission preparation (1-2 weeks)

Renovation projects may be faster depending on scope, while complex new builds may take longer.

Do I need an architect for my project?

While not always legally required, an architect or architectural designer is highly recommended for:

  • New builds over 100m²
  • Complex renovations affecting structure
  • Heritage building modifications
  • Commercial projects

Our team includes qualified architects and designers who can guide you through the entire process.

What is BIM and how does it help my project?

Building Information Modeling (BIM) creates a detailed 3D digital model of your project that:

  • Detects design clashes before construction
  • Provides accurate quantity takeoffs
  • Enables virtual walk-throughs
  • Reduces errors and rework by up to 30%
  • Improves coordination between trades

We use BIM on all major projects to ensure accuracy and efficiency.

Costs & Budget

How much does a new build cost per square meter?

Construction costs in New Zealand typically range from:

  • Standard homes: $2,500 - $3,500 per m²
  • Mid-range homes: $3,500 - $4,500 per m²
  • High-end homes: $4,500 - $6,000+ per m²
  • Commercial buildings: $3,000 - $5,000 per m²

These costs include construction but exclude land, consent fees, and professional services. Renovation costs vary widely based on scope.

What are the hidden costs I should budget for?

Beyond construction costs, budget for:

  • Council consent fees (1-3% of project value)
  • Professional services (10-15% for architects/engineers)
  • Site works and landscaping (5-10%)
  • Contingency fund (10-15% for renovations, 5-10% for new builds)
  • GST (15% on all costs)
  • Utility connections ($10,000 - $30,000)

We provide comprehensive cost breakdowns to avoid surprises.

Is renovation cheaper than building new?

Not always. Consider these factors:

  • Minor renovations are usually cheaper than rebuilding
  • Major structural changes can cost 70-90% of new build costs
  • Hidden issues in older buildings can blow budgets
  • New builds offer better energy efficiency and warranties
  • Renovations may have lower consent costs

We offer free assessments to help determine the most cost-effective option for your situation.

Consents & Compliance

Do I need building consent for my project?

Building consent is required for:

  • All new builds regardless of size
  • Structural alterations to existing buildings
  • Additions over 30m² (some exceptions apply)
  • Changes to fire escapes or safety systems
  • Plumbing and drainage work

Some minor work may be exempt under Schedule 1 of the Building Act. We handle all consent applications for you.

How long does building consent take?

Council processing times vary:

  • Simple projects: 10-15 working days
  • Standard residential: 15-20 working days
  • Complex commercial: 20-40 working days

Add 2-4 weeks for preparation and potential RFIs (Requests for Information). Fast-track options may be available for some projects.

Project Timeline

How long does it take to build a house?

Typical construction timelines:

  • Small home (100-150m²): 4-6 months
  • Standard home (150-250m²): 6-9 months
  • Large/complex home (250m²+): 9-12 months
  • Major renovation: 3-6 months
  • Minor renovation: 4-12 weeks

Weather, site conditions, and material availability can affect timelines. We use project management software to keep everything on track.

Can I live in my house during renovation?

It depends on the renovation scope:

  • Kitchen/bathroom only: Usually yes, with some inconvenience
  • Single room additions: Generally yes
  • Major structural work: Often better to move out
  • Whole house renovation: Definitely need alternative accommodation

We work with you to minimize disruption and can stage work to maintain livability where possible.
