The Biggest Renovation Mistakes Wellington Homeowners Make (And How to Avoid Them)

A renovation can make your home more comfortable, practical and enjoyable to live in. But getting there involves plenty of decisions, and some have a much bigger effect on the budget and timeline than homeowners expect.

A layout decision left unresolved, an unclear quote or a product ordered too late can create problems once work is underway. Wellington’s steep sections, restricted access and older homes can add further considerations.

Orkney Group has been renovating Wellington homes since 2005. That experience has shown us how much the decisions made before construction influence what happens on site. Here are eight renovation mistakes to watch for, along with practical ways to keep your project on track.

1. Starting without a realistic budget and contingency

It’s easy to build a renovation wish list before finding out what it will cost. The difficulty comes when the design develops around a budget that doesn’t cover the work involved.

Your total budget needs to account for more than construction. Depending on the project, design and engineering fees, council fees, appliances, temporary accommodation and finishing work may also need to be included.

There should also be money set aside for unexpected work. If every dollar is already allocated, an unforeseen repair can force difficult compromises elsewhere.

How to avoid it: Discuss your budget with your builder early, including your overall spending limit. Agree on a suitable contingency for the property and scope, and keep that allowance separate from optional upgrades.

Our Renovation Budget Guide explains how to work through the costs and prioritise your spending.

2. Leaving major design decisions too late

“We’ll decide once the builder starts” can sound reasonable. But some choices affect work that happens well before the finished products are installed.

For example, the vanity you choose may influence plumbing positions. Kitchen appliances affect cabinetry dimensions, while lighting and power points need to work with the furniture and layout.

Leaving these decisions unresolved can mean trades are waiting for answers or completed work needs changing.

How to avoid it: Ask your builder and designer which decisions need to be made first, then agree on deadlines. Prioritise anything affecting structure, plumbing, electrical work, cabinetry or products that need to be ordered well ahead.

You don’t need every decorative detail settled immediately, but the team needs enough information to build accurately.

3. Changing the scope once construction has started

Adding something while the team is already on site can seem straightforward. Sometimes it makes sense, especially when unexpected conditions come to light.

However, moving a wall, extending the work into another room or changing a bathroom layout may affect several trades. There may also be materials to reorder, drawings to revise and completed work to alter.

Changes to consented plans need to go through the appropriate council process, which may involve a variation or amendment, and will incur additional costs.

How to avoid it: Take time to agree on a clear scope before construction starts. If you want to make a change, ask for its cost and timing implications, and record the agreed variation in writing before the additional work proceeds.

Keep a running total of approved changes. Several small additions can become a significant amount.

4. Choosing finishes before resolving the layout

Tiles, tapware and paint colours are enjoyable decisions to make. But beautiful finishes won’t solve a kitchen that’s awkward to cook in or a bathroom with nowhere to put towels.

Start with the problems you want the renovation to solve. Is there enough storage? Do doors open into each other? Can two people use the kitchen comfortably? Does the laundry work for your household?

How to avoid it: Walk through your daily routines with your designer and builder. Resolve the layout, storage, lighting and ventilation before committing too much of the budget to decorative choices.

5. Choosing a builder purely on the cheapest quote

A lower price deserves a closer look, just as a higher one does. The key is understanding what each builder has actually allowed for.

One price might include painting, rubbish removal and project management, while another excludes them. Allowances for fittings may also differ considerably.

If you compare only the final figure, you may miss differences that affect both the finished result and the amount you ultimately pay.

How to avoid it: Give each builder the same plans and scope, then compare:

• What is included and excluded.

• Which costs are provisional sums, other allowances or estimates.

• Whether GST is included.

• Who is coordinating the work.

• How unexpected work and changes will be priced.

• 
  

Also consider relevant renovation experience, previous projects and communication. Ask questions until you understand what you’re agreeing to.

6. Underestimating how trades and stages fit together

A renovation involves a sequence of connected tasks. If one stage isn’t ready, several others may need to move.

On one Orkney renovation, a delivery of imported tiles contained inconsistent sizes, making them unsuitable for installation. Sourcing replacements added several weeks, holding up the bathroom fittings and subsequent finishing work.

Similar difficulties can arise when homeowners arrange their own kitchen, fixtures or suppliers without keeping the main contractor informed.

How to avoid it: Be clear about who is coordinating the overall programme. If you’re supplying products yourself, confirm their suitability, delivery dates and installation requirements with your builder before ordering.

Make sure everyone knows who is responsible for ordering, receiving and checking each item. If a delivery date changes, tell the person managing the project promptly.

7. Overlooking Wellington’s access challenges and older homes

The same renovation can involve very different work depending on the property.

A house reached by steps or a narrow path needs a different delivery plan from one with a flat driveway.

Limited parking and storage space can also affect how materials, equipment and waste are handled.

Older homes bring another layer of uncertainty. Existing plans may not reflect previous alterations, and parts of the structure may only become clear once walls or floors are opened. Matching older materials and working with uneven surfaces can also take additional care.

How to avoid it: Arrange a site visit early. Discuss access, deliveries, scaffolding, material storage and protection of the areas being retained.

Share any plans, property records or information about previous work. Ask your builder what can be investigated beforehand and what may remain uncertain until construction begins.

8. Allowing too little time before construction begins

A construction timeframe is only one part of the overall renovation programme.

Before work starts, you may need time for design, engineering, pricing, product selections and consent documentation. Custom windows, cabinetry and other made-to-order items also need to fit into the schedule.

Check consent requirements early with your designer, builder or council. Some work is exempt, but you shouldn’t assume that an internal renovation automatically falls into that category.

How to avoid it: Tell your builder about any important deadline at the first conversation. Work backwards together to establish whether it is realistic, allowing for preparation as well as construction.

Confirm product availability before relying on a delivery date, and leave room for unexpected issues rather than planning everything around the earliest possible finish.

How to Avoid Renovation Mistakes Wellington Homeowners Make

Many of the renovation mistakes Wellington homeowners make can be avoided with a realistic budget, clear priorities and decisions made early.
