“How much should we spend on the outside?” It’s one of the questions I’m asked most often. Most homeowners have no real sense of what to allow, which is completely understandable. Exterior upgrade costs for a renovation or a new build isn’t something you can look up on a price list, because the range is enormous.
At one end, you could spend a thousand dollars on a DIY paint job and a new letterbox. At the other end, you could spend hundreds of thousands, or more than a million on a substantial home. The right figure for your house sits somewhere in between, and over the years I’ve found a few reliable ways to work out where.
Start With What You’ve Already Spent Inside
Many of the homeowners who come to me have already renovated the inside of their home. Not everyone, but a lot of them. New kitchen, new bathrooms, custom joinery, beautiful lighting. Then they stand on the footpath, look back at the house, and realise the outside no longer matches the home they live in.
This is one of the most useful places to start. The exterior is the first thing you see every time you come home, and the first thing everyone else sees too. If the interior has had a considered, high-quality renovation and the exterior hasn’t, pulling into your driveway becomes a bit of a letdown.
What you spent inside tells you the standard you’ve already set. The outside should meet it.
Let Your Property’s Value Guide Your Exterior Upgrade Cost
The second piece of the puzzle is what the property is worth. A $500,000 home and a $10 million home call for very different levels of investment.
That doesn’t mean a $500,000 home can’t have something really special. Good design isn’t reserved for expensive houses. But you probably wouldn’t put $200,000 into the façade of a $500,000 property. On a home worth $3M, $4M or $5M or more, spending $150,000 to $200,000 or more is far more realistic. It depends on where the house is starting from, of course.
As a rough guide, I suggest allowing a minimum of 5% of the property’s value. Most of the projects I work on have a budget of at least $100,000 – $150,000 – and often that’s for the façade alone.
The key is not to scrimp on a valuable property. An exterior that falls short of the home’s quality can pull its value down, and it’s the kind of decision people come to regret.
Why Every Last Detail Matters
Most people can choose the big things. The colours, the cladding profile, perhaps a new front door. Those choices matter, but they aren’t what separates a quick, inexpensive renovation from one that looks exceptional.
The difference is in every last detail:
- The depth of the bulkhead over the entry, which decides whether it reads as solid architecture or a thin afterthought
- The height and placement of wall lights, set in proportion to the doors, windows and walls around them
- The joint where two surfaces meet, detailed so it looks intentional rather than stuck on
- The scale of the stone in relation to the scale of the house
- The balance between texture and simpler surfaces, so there’s enough interest while the house still has room to breathe
- How the details of the front fence pick up the lines and materials of the house, so the two read as one design
- Practical elements like capping and waterproofing, designed to protect surfaces while still looking considered
Each of these seems small on its own. Together, they decide whether a home looks resolved or simply updated. This applies to new builds as much as renovations. When you don’t work in this field every day, it’s hard to know these details exist, let alone resolve them. Yet they’re what give a home real presence on the street.
This is also where I see money go astray. Some people save on design advice and gather ideas online instead, or ask AI for suggestions. That can be a useful starting point, but an image can’t tell you how it will be built, how long it will last, or what it will cost. The result is often spending too much in the wrong places, or too little on the things that would have made the biggest difference.
Exterior Upgrade Cost for Renovations and New Builds
When I think about exterior upgrade cost for renovations and new builds, I see it in layers.
At one level, you might paint the house, replace some cladding, update the lighting and add new landscaping. That’s a legitimate refresh. On a lower-value home, or one you plan to sell in the next year or two, it can be exactly the right call.
The deeper level looks at the house as a whole: its form, its scale and proportion, and how it will look in 10, 15 or 20 years. That approach costs more upfront. Over the life of the home, it usually costs less, because the work doesn’t need to be redone a few years later.
There’s an old saying that the poor man pays twice. I see it play out more often than you’d think. A cheaper fix now can lead to a second renovation much sooner than expected.
Thinking 20 Years Ahead
On a valuable property, an exterior upgrade shouldn’t be a quick flip. Done well, it’ll add value and longevity, so that in 15 or 20 years the house still looks right and doesn’t need updating again.
Then there’s the budget itself. Figures from early research are often optimistic, and the real exterior upgrade costs only become clear once everything is specified. Having someone with a realistic sense of what things cost by the end of the project can save a lot of stress.
Before You Settle on a Number
If you’re working out a budget for your own home, these are the things I’d keep in mind:
- Let your interior renovation set the standard for the exterior.
- Treat 5% of your property’s value as a starting point, not a ceiling.
- Put money into detailing and construction quality, not only colours and cladding.
- Plan for how the house will look in 20 years, not just next year.
If your property is worth more than about $2 million, I really encourage you to take your time and bring in someone who works in this field, whether that’s me or another experienced professional. You want advice on how it will look, how it will last and what it will realistically cost.
