Before You Spend a Dollar on Design, Read This

You have an idea. Maybe it has been sitting in the back of your head for months.

A granny flat out the back for Mum. A garage conversion into something actually useful. An extra bedroom. A second dwelling you could rent out. Maybe just a proper renovation that finally makes the house work for your family.

You have probably already talked to someone. A builder friend. A neighbour who did something similar. Maybe you have even pulled out a tape measure and had a poke around yourself.

And it feels possible. It feels like it should work.

Here is the thing nobody tells you early enough: feels possible and actually possible are two very different things. And the gap between them can cost you thousands of dollars before you even break ground.

The Expensive Way to Find Out

Most people find out what is and is not possible on their site the hard way.

They hire a designer. Get drawings done. Fall in love with the concept. Then someone mentions resource consent. Or the setbacks are wrong. Or the zoning does not allow what they had in mind. Or the council wants a geotechnical report because of the slope. Or the neighbours have rights they did not know about.

Suddenly the $15,000 renovation has a $40,000 consent process attached to it. Or the second dwelling cannot go where everyone assumed it would. Or the whole idea needs to be rethought from scratch.

At that point, you have already spent money on design work that cannot move forward without a major rethink.

It is a genuinely awful situation to be in. And it is more common than most people realise.

What a Feasibility Study Actually Does

A feasibility study is not glamorous. There are no renders. No mood boards. No exciting sketches of what your future home could look like.

What it is, is honest.

It looks at your specific site, your specific idea, and tells you plainly what the rules say, what the likely pathway looks like, and where the risks are. Before you spend more.

For a property in New Zealand, that means looking at things like:

• Your District Plan zoning. Different zones have different rules. What is allowed in one area is not allowed in another. Your site might be zoned in a way that makes your idea straightforward, or it might throw up complications you did not see coming.

• The planning controls that apply to your site. Height limits. Setbacks from boundaries. How much of your site you can actually cover with buildings. Recession planes (the angled rules that stop buildings from looming over neighbours). These rules are not negotiable, and they affect what can fit where.

• Activity status. Some things are permitted, meaning you just build them. Others are controlled, restricted discretionary, or discretionary, meaning you need consent and someone gets to have an opinion about your project. Knowing which category you fall into matters a lot for your timeline and your budget.

• Overlays and special conditions. Flood plains. Heritage zones. Natural hazard areas. Coastal environments. These can add requirements or restrictions that are completely invisible until someone looks for them.

• Consent requirements. Will you need resource consent, building consent, or both? What is that process likely to look like for your specific project?

  
  

• The risks and unknowns. What questions still need answering? What specialist advice might you need further down the track?

This is the picture you need before you start spending serious money.

Why This Matters More Than People Think

Here is a real pattern that plays out all the time.

Someone wants to build a minor dwelling on their section. They talk to a builder. The builder says sure, no problem, I have done heaps of these. They get a quote. The quote looks reasonable. They start thinking about how to use the rental income.

Then they actually look at the District Plan. The site is in a zone where a second dwelling requires resource consent. The consent process takes six months and costs $8,000 in council fees alone, before you factor in the consultant time to prepare the application.

Or they discover the site coverage rules mean the new building would push them over the allowed limit. Or the only sensible place to put it is in a setback. Or the access to the rear of the section does not meet the rules.

None of these things are insurmountable. But they are things you need to know before you are emotionally and financially committed to a plan.

A feasibility study tells you this stuff upfront. So you can make a proper decision with the actual facts in front of you.

"Can't I Just Call the Council?"

Yes, and you should. Council duty planners can be genuinely helpful for basic questions. But there are limits.

A council planner will answer a specific question. They will not look at your whole project and tell you everything you need to know. They are not there to be your advisor. They will answer what you ask, and if you do not know the right questions to ask, you will walk away thinking you are fine when there is something you missed.

There is also the challenge that most people are not fluent in planning language.

Asking a planner whether your project is okay when you do not yet understand the rules is a bit like calling a doctor and describing your symptoms in the wrong terms. You might get a useful answer, or you might talk past each other entirely.

A proper feasibility review takes your project, applies the relevant rules, and explains what they mean for you in plain language. That is a different thing.

What Good Early Advice Looks Like

At MAV Studio, a Site Feasibility Report costs $1,475 plus GST.

• You're buying a clear answer to the question: is this realistic, and what does it take to get there?

• You are buying protection against the much more expensive mistake of commissioning full design work before you know the planning picture.

• You are buying a document you can actually use. Take it to a builder for a more informed conversation. Take it to a mortgage broker or bank when you are working out finance. Use it to make a confident decision about whether to proceed, adjust, or step back.

The report looks at your proposed project and intended outcome, the planning rules that apply to your property, what consent is likely to be required, the key risks and constraints, and a recommended next step.

It is prepared from Wellington and covers properties all over New Zealand. Most of the early feasibility work draws on council records, District Plan rules, property files, and aerial imagery, so a site visit is not always necessary. Where one is, the report will say so.

The Question Worth Asking First

Many people get caught out spending money in the wrong order.

They start with the exciting stuff. The design. The quotes. The vision of what it could be.

Then they hit a wall they could have seen coming, and they have to spend more money to get around it, or they walk away from something they had already invested in.

The smarter move is to spend a little money early to understand what you are actually dealing with. Then spend the bigger money with confidence.

If your project stacks up, you will know it. If there are complications, you will know about them before they become expensive surprises. And if something is not going to work the way you imagined, better to find out now than after the drawings are done.

That is what a feasibility study is for.
