G’day, Perth homeowners! If you’re feeling a bit squeezed in your single-story abode, you’re not alone.

With our growing families and changing lifestyles, many Perth residents are looking up, quite literally, for their home expansion solutions.

Adding a second story to your home can be a brilliant way to gain space without sacrificing your backyard or moving to a new suburb. But let’s face it, it’s a big job that requires careful planning and execution.

So, let’s dive into the nitty-gritty of second story additions, Perth-style.

The Up and Up of Home Expansions

I remember the first time I worked on a second story addition in Subiaco.

The owners, a lovely couple with three growing kids, were torn between moving to a bigger home or expanding their current one. “We love our neighborhood,” they said, “but we’re bursting at the seams!” By the end of the project, they had doubled their living space while keeping their prized location.

The look on their faces when they saw their transformed home for the first time – that’s why I love what I do.

So, whether you’re in a character home in Fremantle, a mid-century gem in City Beach, or a modern build in Ellenbrook, here’s what you need to know about reaching for the sky with your home.

1. Is Your Home Suitable for a Second Story Addition?

Before you start dreaming of upstairs views, we need to make sure your home can handle the extra weight:

• Foundation check: Your current foundation needs to be strong enough to support a second story.
• Structural integrity: The existing walls and roof structure will need assessment.
• Local council regulations: Check height restrictions and setback requirements in your area.
• Heritage considerations: If your home is heritage-listed, there may be additional restrictions.

I once worked on a 1920s weatherboard in Mount Lawley. We had to get creative with reinforcing the foundations, but the end result was a stunning blend of old and new that respected the home’s heritage while meeting the family’s modern needs.

2. Design Considerations: Blending Old and New

A successful second story addition should look like it was always meant to be there:

• Architectural style: The addition should complement the existing style of your home.
• Proportions: Consider how the addition will affect the overall look of your home from the street.
• Staircase placement: This can have a big impact on both the ground floor and upper floor layouts.
• Light and ventilation: Think about window placement to maximize natural light and airflow.

In a recent project in Wembley, we designed a second story that mimicked the pitch of the existing roof. From the street, it looked like a natural extension of the original California bungalow style.

3. Budgeting for Your Upward Expansion

Let’s talk turkey – adding a second story isn’t cheap, but it can be a smart investment:

• Cost range: In Perth, expect to pay anywhere from $1,500 to $3,000 per square meter for a second story addition.
• Hidden costs: Factor in things like upgrading electrical systems and plumbing.
• Contingency: Always add a 10-20% buffer for unexpected issues.
• Value add: Consider how much value the addition will add to your home.

I worked with a family in Scarborough who initially balked at the cost. But when we compared it to the cost of buying a larger home in the same area (plus stamp duty and moving expenses), the addition started to look like a bargain.

4. The Importance of Good Planning

Proper planning can save you headaches (and dollars) down the track:

• Detailed drawings: Invest in comprehensive architectural plans.
• Engineering reports: These are crucial for ensuring structural integrity.
• Council approval: Start this process early as it can take time.
• Timeline: Be realistic about how long the project will take.

I can’t stress this enough – good planning is everything. I once had clients in Nedlands who rushed the planning stage. We ended up having to make costly changes mid-construction because they hadn’t fully thought through the layout.

5. Choosing the Right Builder

Not all builders have experience with second story additions. Here’s what to look for:

• Specialization: Look for builders with specific experience in second story additions.
• References: Ask for examples of similar projects they’ve completed.
• Insurance: Ensure they have appropriate insurance for this type of work.
• Communication style: You’ll be working closely with them, so make sure you’re on the same wavelength.

I always encourage my clients to speak with past customers. It’s the best way to get a feel for how a builder works and what the process will be like.

6. Preparing for the Build

Adding a second story is a major undertaking. Here’s how to prepare:

• Protect the ground floor: Your builder should have strategies to protect your existing home.
• Temporary roofing: This is crucial to protect your home from the elements during construction.
• Living arrangements: Decide whether you’ll stay in the home or move out during construction.
• Neighbors: Give your neighbors a heads up about the upcoming work.

I worked on a project in South Perth where the family decided to stay in the home during construction. We set up a temporary kitchen in the garage and scheduled the noisiest work for when they were out. It requires flexibility from both the family and the building team, but it can be done.

7. Structural Considerations

Adding a second story isn’t just about plonking a new level on top of your existing home:

• Load-bearing walls: Identify which walls are load-bearing and may need reinforcement.
• Roof removal: In most cases, the existing roof will need to be removed.
• Steel beams: These are often used to support the new floor.
• Bracing: Additional bracing may be needed to support the new structure.

In a Cottesloe project, we discovered that the original 1970s home hadn’t been built to support a second story. We ended up having to add significant structural reinforcement, which was costly but necessary for safety and longevity.

8. Staircase Strategies

The staircase is a crucial element in a second story addition:

• Location: Consider how the staircase will impact both the ground floor and upper floor layouts.
• Style: The staircase can be a design feature in itself.
• Space-saving options: Things like spiral staircases or step-savers can be good for tight spaces.
• Building codes: Ensure your staircase meets all relevant building codes and regulations.

I worked on a narrow terrace in West Perth where space was at a premium. We ended up designing a custom steel staircase that doubled as a bookshelf. It became a real talking point of the home.

9. Plumbing and Electrical Considerations

Adding a second story means extending your home’s systems:

• Plumbing stack: You may need to extend the main plumbing stack to the new level.
• Electrical upgrade: Your current electrical system may need upgrading to handle the additional load.
• Heating and cooling: Consider how you’ll heat and cool the new space.
• Smart home integration: This can be a good time to add smart home features.

In a recent Applecross project, we took the opportunity to completely overhaul the home’s electrical system, adding smart home features that allowed the owners to control lighting, heating, and security from their phones.

10. Windows and Natural Light

Good window placement can make or break a second story addition:

• Orientation: Consider the sun’s path when placing windows.
• Privacy: Think about sightlines to and from neighboring properties.
• Energy efficiency: Use double-glazing and consider low-e glass for better insulation.
• Skylights: These can be great for bringing light into central areas.

I worked on a home in City Beach where we installed floor-to-ceiling windows to capture stunning ocean views. We used smart glass that could be tinted electronically to manage heat and glare.

11. Insulation and Energy Efficiency

A second story addition is a great opportunity to improve your home’s overall energy efficiency:

• Roof insulation: Proper insulation in the new roof space is crucial.
• Wall insulation: Don’t forget to insulate the new exterior walls.
• Thermal breaks: These can help prevent heat transfer between the old and new parts of the home.
• Solar panels: Consider if this is a good time to add solar panels to your home.

In a recent project in Yokine, we used high-performance insulation and added solar panels. The owners were thrilled with how comfortable the whole house became, not just the new addition.

12. Blending Interior Styles

Your new addition should feel like a natural extension of your existing home:

• Consistent finishes: Try to match or complement existing finishes where possible.
• Flooring: Consider how the flooring will transition between the old and new sections.
• Color scheme: A consistent color scheme can help unify the spaces.
• Period features: If you’re adding to a character home, consider replicating period features in the new space.

I worked on a federation home in Claremont where we carefully matched the ornate ceiling roses and cornices in the new upstairs rooms. It was a challenge, but the result was seamless.

13. Outdoor Spaces in the Sky

Don’t forget about outdoor space in your second story addition:

• Balconies: These can add valuable outdoor living space.
• Roof terraces: Flat roof sections can be transformed into usable outdoor areas.
• Privacy screening: Consider how to create privacy for these elevated outdoor spaces.
• Weight considerations: Ensure your structure can support the weight of outdoor areas, including when they’re full of people.

In a Fremantle project, we created a stunning roof terrace with views over the port. We used composite decking to reduce weight and added a glass balustrade to maximise the view while ensuring safety.

14. Dealing with Disruption

Adding a second story is a major project that will disrupt your life:

• Timeline: Be prepared for the project to take several months.
• Noise and dust: These are inevitable, even with the best dust control measures.
• Site access: Your yard will likely be taken over by equipment and materials.
• Flexibility: Be prepared for changes and unexpected issues.

I always have an honest conversation with my clients about what to expect. Those who are mentally prepared for the disruption tend to handle the process much better.

15. The Final Touches

As your project nears completion, don’t forget about these important final steps:

• Painting: A fresh coat of paint can help blend the old and new sections.
• Landscaping: Your yard will likely need some TLC after the build.
• Styling: Consider how you’ll furnish and decorate your new spaces.
• Certification: Ensure you get all the necessary final inspections and certifications.

I remember a project in Mount Lawley where the owners had us build a custom library as part of their second story addition.

Seeing their books finally unpacked and arranged in the new space really made the house feel like a home again.

Wrapping It Up

Adding a second story to your Perth home is a big undertaking, but it can also be incredibly rewarding.

It’s a chance to reimagine your home, to create space for your growing needs, and to add significant value to your property.

Remember, every home is unique, and what works for one might not work for another.

That’s why it’s crucial to work with experienced professionals who understand the specific challenges and opportunities of building in Perth.

From our unique climate to local council regulations, there’s a lot to consider.

But don’t let the challenges deter you. I’ve seen families fall in love with their homes all over again after a second story addition.

I’ve seen kids excitedly picking out their new bedrooms, parents finally getting the master suite they’ve always dreamed of, and grandparents able to move in and be close to family.

Whether you’re in an old worker’s cottage in Fremantle, a 70s brick and tile in Dianella, or a modern home in Harrisdale, a second story addition can transform your home and your lifestyle.

It’s about creating space for your life to unfold, for your family to grow, and for new memories to be made.

So, Perth homeowners, if you’re feeling squeezed and looking to the sky for answers, know that you’re not alone. With careful planning, the right team, and a clear vision, your home can grow with you, reaching new heights – quite literally!

Here’s to your home expansion journey, Perth. May your new views be spectacular, your new spaces be filled with joy, and your expanded home be everything you’ve dreamed of and more. Happy building!
