Bishop Constructions Second Storey Extensions

Modern Brisbane home featuring a newly completed second storey extension.


When you live in a major Australian city such as Brisbane, it often makes sense to build up and extend, as opposed to buying a larger block of land. That is where we come in, we provide professional second storey house extensions across all Brisbane suburbs.

Our years of house extensions and building experience allow us to provide our clients with a seamless delivery process, staying within budget whilst delivering immaculate extensions to our clients. As there are various ways to approach this, one of the first steps is to get a professional design, and we are more than happy to provide construction drawings to help with the design process.

As a local team of builders, we know how to make the most of your existing property and turn unused roof space into comfortable new living areas.

Our years of house extensions and building experience allow us to provide our clients with a seamless delivery process, staying within budget whilst delivering immaculate extensions to our clients. As there are various ways to approach this, one of the first steps is to get a professional design, and we are more than happy to provide construction drawings to help with the design process. From the first design sketch through to the final build, our team treats every project as if it were our own home.

Once you have your design, it is time to take the roof off and lift it up to create an additional storey on top of your home. This roof lift process is also referred to as a second storey building, addition, extension, or simply a build-on-top. It is one of the smartest ways to add space without giving up your backyard or moving away from the suburb you love.

There are many benefits to a second storey extension, and if you are considering adding more space, getting a better view, capturing more sunlight, and increasing the value of your home. It also makes sure you give Bishops a call to discuss your best options. Whether you want a couple of extra bedrooms, a parents’ retreat, or a whole new living zone, second storey extensions give you room to grow on the land you already own.

We are able to provide a free quote in most Northside and Southside Brisbane suburbs, so feel free to contact us today to get a free quote for your next house extension project. Our team of builders is ready to talk through your renovations, walk you through the design, and turn your property into the home your family needs. Get in touch and let us help you build something you will love for years to come.

  • No stamp duty or agent fees
  • Better views and more natural light

Sell up, find a larger property, and start again somewhere new.

  • Stamp duty, agent fees, moving costs
  • New schools, commutes and neighbours
  • Bigger blocks near the city are scarce

What Does a Second Storey Extension Cost in Brisbane?

Builders completing a roof lift as part of a second-storey extension project.

The honest answer is that no two builds are priced the same. The cost of adding a second storey extension to your house depends on the size of the new floor, your existing structure, site access, and the finishes you choose. A simple extension over part of the home sits at one end, while a full second-level extension with multiple rooms and a new staircase sits at the other.

Rather than quote a figure that may not match your extension project, we give you a fixed-price building quote before construction starts, so you know your costs with no surprises midway through. Factors that shift the budget include engineering requirements, council approvals, and whether the roof lift needs structural upgrades below.

Want a real number for your home? Contact Bishop Construction Services on 07 3469 5110 for a free quote tailored to your property. Our team has spent years delivering second storey extensions and renovations across Brisbane, so we know how to plan the work around your living areas and keep disruption to a minimum while we build. From the first contact through to handover, our team of builders will guide you through every stage, helping you create the extra living space your growing family needs without leaving the property you already love.

Whether you are after extensions, renovations, a couple of new bedrooms, a fresh living zone, or a full upper-level transformation, our house extensions and renovations are built to last and finished to a high standard. Get in touch with our team today, tell us about your property, and let our builders show you how much more space your home can offer with a well-planned second storey extension.

What Moves the Budget on a Second Storey Extension

A rough guide to which factors add the most to a second storey build. Every home is different, so we confirm the real figures in your fixed-price quote.

Internal finishes and fittingsLower impact
Size of the new floorModerate
New staircase and reconfigured lower floorHigher
Structural upgrades below the roof liftBiggest swing

The honest takeaway: it is the structure underneath, not the finishes on top, that swings a budget most. That is exactly why we assess your slab and framing before we quote a fixed price.

Our Second Storey Building Process, Step by Step

A second storey addition runs more smoothly when you know what comes next. Over 20 years of building across Brisbane, we have refined a process that keeps your project on track from the first contact to handover:

Initial consultation – we visit your home, examine your space, talk through your ideas, and assess whether your house suits building upward.
Design and drawings – we provide construction drawings to shape your floor plan, elevations, and layout.
Approvals – we coordinate council and building approvals so the paperwork is handled for you.
Roof lift and construction – the roof comes off, the new storey goes up, and licensed trades complete the build.
Completion – you walk through your finished second storey, built to a high standard and ready to live in.

Five Stages, One Team, Start to Handover

You deal directly with us the whole way through. No subcontracted project manager, no being passed around.

Which Brisbane Houses Suit a Second Storey Addition?

Most homes can take a second storey, but some suit it more easily than others. After 20 years building across Brisbane suburbs, we have worked on a wide range of properties and can tell you early whether yours is a good candidate for building upward. The types that tend to suit second storey extensions well include:

Queenslanders – already raised and structurally suited to a roof lift and a new level.
Post-war homes – solid footings that often handle an added storey with the right engineering.
Brick veneer houses – common across middle-ring suburbs and well-suited to going up.
Single-storey builds on smaller blocks – ideal where extending out would eat your backyard.

Building Up vs Extending Out: Where the Difference Sits

Factor Extending out (ground floor) Second storey extension
Backyard Eats into your outdoor space Keeps the yard you already have
Block size needed Needs spare land to spread onto Works on tight inner and middle-ring blocks
Views and light Stays at ground level Captures better views and more sunlight
Living downstairs during the build Disruption spreads across the home Work happens above, we plan to limit disruption
Adding bedrooms and a retreat Limited by available footprint A whole new floor of living to plan

The only way to know for certain is an on-site look at your structure, slab, and existing layout. We assess all of this during your free consultation, then give you clear, honest advice on the best way forward for your home.

Second Storey Extensions Brisbane: Common Questions

How much does a second storey extension cost in Brisbane?

No two builds are priced the same. The figure depends on the size of the new floor, your existing structure, site access and the finishes you choose. Rather than guess, we give you a fixed-price quote before construction starts so there are no surprises midway through.

Can I stay living in my home during the build?

In many cases yes. Because the work happens above your existing living areas, we plan the roof lift and construction to keep disruption to a minimum. We will talk you through what to expect for your specific home during the consultation.

Does my house need to be a Queenslander to go up?

No. Queenslanders, post-war homes, brick veneer houses and single-storey builds on smaller blocks can all suit a second storey. The only way to be sure is an on-site look at your structure, slab and layout, which we do during your free consultation.

Do you handle council approvals?

Yes. We coordinate council and building approvals so the paperwork is handled for you. Two decades working across Northside and Southside Brisbane means we know the local council requirements.

What is the difference between a second storey extension and a house raise?

A second storey extension lifts the roof and adds a new level on top. House raising lifts the whole home so you can build in underneath. We do both, and during the consultation we will advise which suits your block and goals.

Will a second storey add value to my home?

Adding extra bedrooms, a parents’ retreat or a new living zone increases usable space and is one of the smartest ways to lift a home’s value, especially when you want to stay in a suburb you love rather than pay to move.

Which Brisbane suburbs do you cover for second storey extensions?

We work across Northside and Southside Brisbane from our Greenslopes base, including Holland Park, Morningside, Chermside, Indooroopilly, Carindale and many more. If your suburb is not on our list, call us. We almost certainly service it.
