Choosing between a single or double-story home on the Sunshine Coast is one of the first big decisions you’ll make. The best choice depends entirely on your block, budget, and lifestyle. A single-story home offers sprawling, accessible living, while a double-story home is the key to maximizing views and space on a smaller footprint.
This includes guidance on:
- Single-Story Homes
- Double-Story Homes
- Which is More Expensive?
- How to Make the Right Choice for Your Lifestyle
This guide will help you weigh the pros and cons for your specific situation. It will ensure your New House Builds plan is perfect for your family for years to come, whether you’re debating a Knock Down Rebuild Vs. Buying Land or starting on a new block.
As custom builders, we’ve mastered both styles, from sprawling hinterland retreats to narrow-lot coastal homes. We can help you make the right call. To discuss your project, Contact Our Team for an expert consultation.
Single-Story Homes
A single-story home places all your living areas, bedrooms, and amenities on one convenient level. It’s prized for its open-plan flow and total accessibility, making it the perfect choice for wider or acreage blocks, or for those planning to “age-in-place” in their forever home.
On the Sunshine Coast, this style is ideal for hinterland properties or clients who want to create a seamless, resort-style connection between all living spaces and the pool or garden. It’s also a fantastic, flowing layout for a Home Renovations project where you’re adding a large new wing.
Pros: Accessibility & Flow: With no stairs, this design is perfect for young children and is a future-proof solution for aging-in-place. It allows for beautiful, wide-open-plan living.
Cons: The Larger Footprint: A single-story home requires a wider, larger block of land, which can be a significant cost or simply unavailable in established coastal suburbs.
Cons: Less Privacy: Bedrooms are often located closer to the main living and entertaining areas, which can be a noise and privacy challenge. This is one of the key Questions To Ask Your Building Designer so they can create a smart, zoned layout.
Double-Story Homes
A double-story home stacks your living space vertically, allowing you to fit a much larger home on a smaller block of land. This is the most popular and logical choice for maximizing land value in coastal suburbs and is absolutely essential for capturing those prized ocean or hinterland views.
In sought-after suburbs like Shelly Beach or Moffat Beach, building up is often the only way to get the family-sized home and the coastal view you’re paying for. A double-story layout also provides fantastic design flexibility, allowing us to create separate zones for parents and children. This separation is a key principle of a Timeless Interior Design as it separates public and private spaces.
Pros: Maximise Your Block & Views: This is the biggest benefit. You get more house on less land, and it’s the only way to get “level two” views of the ocean or hinterland.
Pros: Excellent Privacy & Zoning: You can create distinct zones, such as a parents’ retreat and office upstairs, with the main living and guest areas downstairs, which is ideal for a busy family.
Cons: Stairs & Accessibility: Stairs are a major consideration for future mobility. We can design for this by placing a master bedroom and ensuite on the ground floor.
Which is More Expensive?
It’s a common myth that a double-story home is always cheaper per square metre. While you do save on the roof and foundation slab, these savings are almost always offset by the high cost of engineering, structural steel, extensive scaffolding, and high-end staircases. In our experience, a double-story build is typically a higher total investment.
A single-story home has a larger, more expensive concrete slab and roof. A double-story home requires a more complex foundation, a suspended concrete slab for the second floor, and significant extra engineering and safety equipment. We provide a fully detailed breakdown of these costs during our Interior Design and quoting process.
Single-Story Costs: A larger, more costly foundation and roof, but the construction process is generally simpler, faster, and requires no scaffolding.
Double-Story Costs: A smaller foundation and roof, but this is offset by significant extra costs for structural engineering, steel, and scaffolding.
The Verdict: A double-story home often has a higher total build cost, but it is the best way to maximise the value of a smaller, premium block, like our Award-Winning Bokarina Home.
How to Make the Right Choice for Your Lifestyle
The best choice is not about cost, but about your 10-year plan. A single-story home is an exceptional choice for accessibility and seamless open-plan living. A double-story home is the superior solution for maximising a small block, capturing ocean views, and creating separate living zones for a growing family.
We’ve seen clients in Buderim choose a sprawling single-story for an acreage block, while clients in Dicky Beach build up to get that ocean breeze and view. We’ll help you review your block’s potential and your family’s needs to make the perfect call.
Choose a Single-Story If: You are building on a large or wide block, you’re a retiree or downsizer, or you want to eliminate stairs for “aging-in-place.”
Choose a Double-Story If: You are building on a narrow or small block, you want to capture coastal or hinterland views, or you need to create separate living zones for a large family.
Final Consideration: Your choice will fundamentally shape your home’s character, so it’s one of the first and most important decisions you’ll make in the design process.
Frequently Asked Questions (FAQs)
Here are a few of the most common, and most important, questions we answer for our clients.
Q1. Is it cheaper to build a two-story or a single-story home on the Sunshine Coast?
It’s a common myth that a two-story home is always cheaper per square metre. While you save on the roof and foundation, this is often offset by several significant costs.
Key cost factors for a double-story build include:
- The high cost of structural engineering and steel.
- The expense of hiring and using scaffolding for the entire build.
- The inclusion of high-quality internal and external stairs.
- More complex installation for services like plumbing and electrical.
In our experience, a high-quality Luxury Home on The Sunshine Coast will have a similar total build cost, so the decision should be based on lifestyle, not just cost.
Q2. Are two-story homes more energy-efficient to heat and cool in Queensland?
A two-story home can be very energy-efficient when zoned correctly (e.g., cooling only the bedrooms at night). However, a well-designed single-story home often has a distinct advantage in capturing cross-ventilation, which is perfect for the mild Sunshine Coast climate and can reduce cooling costs significantly.
Q3. What is the best option for a sloping block?
For a sloping block, a double-story or split-level home is almost always the superior choice. A single-story home on a steep site creates massive, expensive challenges.
A multi-level design, in contrast, works with the land and avoids issues like:
- Massive, expensive earthworks (cut and fill).
- The need for extensive and costly retaining walls.
- Poor drainage issues created by altering the land.
- A less dynamic home with potentially compromised views.
Q4. Which style has better resale value on the Sunshine Coast?
This depends entirely on the suburb and the block’s potential. There is no single answer, as the market values different features in different locations.
- For view-dependent suburbs (e.g., coastal or hinterland): A double-story home that captures ocean or mountain views will have a significantly higher resale value.
- For family-friendly estates or retiree areas: A well-designed, accessible single-story home can be in higher demand and command a premium.
