The best home additions look like they belong.
A well-designed first-floor addition should feel like it was always meant to be part of your home. At Add-Style, we design and build first-floor additions that seamlessly complement your existing property while creating the extra space your family needs.
With years of experience, our team understands that the success of an addition comes down to the details. From the initial design and planning through to construction and completion, we carefully consider the existing character, layout and structure of your home to create a finished result that feels cohesive and natural.
Whether you’re adding bedrooms, bathrooms, living areas or creating a completely new level, we can help you make the most of your home—adding space, functionality, character and long-term value.

Home Renovations
Transform Your Home From the Ground Up.
Planning a first-floor addition? Why stop upstairs?
At Add-Style, we can transform your entire home by combining a beautifully designed new first floor with a complete ground-floor remodel. Whether you’re looking to create more bedrooms and living space upstairs, modernise your existing ground floor, or completely rethink how your home works for your family, we can bring it all together under one project.
With thousands of second-storey additions, extensions, and renovations completed throughout Sydney, our experienced team understands how to seamlessly connect new and existing spaces. From reconfiguring your ground-floor layout and upgrading kitchens, bathrooms and living areas, to designing and building a brand-new first floor, we manage every stage of the renovation.
The result is a home that feels cohesive, functional and purpose-built around the way you live—both upstairs and down.
One team. One complete renovation. A home transformed from the ground up.

Why choose us?
Affordable Prices
We provide value for money and affordable builds and renovations.
Where possible we tailor our design approach to your budget requirements.
High quality construction
Our superior craftsmanship demonstrates our attention to detail and commitment to quality in construction and materials.
Each of our qualified builders and preferred sub-contractors have been selected for their high standard of expertise and professionalism.
Reliable Costings
Because we are a full-service design and build company, we offer the considerable advantage of being able to give you a firm quotation before you outlay any large amounts of money.
In comparison, when architectural design is completed separately, there is little or no certainty about how much the design will actually cost to build until much further down the track.
Management of concept to completion
As a design builder, we bring together all elements of your project under one contract and one unified workflow – it’s a seamless delivery from initial concept through to completion.
Our team takes care of all details on your behalf – applying for CDCs or DAs, obtaining structural certifications, advising on materials and fittings, site preparation and rubbish removal, organisation of trades and final handover.
Brilliant Designs
Why do our jobs look so good? We have three designers with Architecture degrees and 4 with design diplomas
We believe in the importance of working with you to design spaces that meet your needs, reflect your personal style and provide valuable return on investment. We use an innovative design software program called ArchiCAD to present you with computer generated images that allow you to visualise the design in its completed form.
Our designers are highly experienced, with 65 years of experience between them in designing additions and renovations for Add-Style.
Experienced, licensed professionals
Add-Style is licensed and holds contract works insurance, public liability, professional indemnity and Workers Compensation.
We care about quality and compliance – all building work we perform is in strict accordance with the Building Code of Australia and all our contracts are insured with the Home Building Compensation Fund.
No nasty surprises
We guarantee our fixed price quotes so you won’t be left questioning additional costs for unexpected work.
There’s no conflict between designer, owner, builder and sub-contractors when things go wrong because we are one team and it is our responsibility to ensure your job gets done on time and without mishap.
Trustworthy guidance
We are in the rare situation of being a company in the northern beaches to have held the same building licence since 1987.
This means we’ve never become bankrupt or involved in unlawful activity and for three decades have operated a thriving business under a strict code of integrity and professionalism throughout that time.

How we work
First Meeting
One of our design consultants meets you at your home to discuss your requirements, budget and general feasibility of the project.
Second meeting
Our design team carries out a site inspection and measure up to establish design constraints such as sunlight, shade, views, privacy and compliance with council or private certifier codes. At that meeting we sit down with you, the client, and discuss and develop the brief of your requirements.
Third meeting, a week or so later
We get in touch with you to present our first home extension design together with a verbal estimate of costs. Often it’s worth presenting more than one design with a view to choosing the best and developing it to suit the property owner’s needs.
Fourth meeting, a week or so later
Once we have your feedback and changes and you are happy with the design, the next step is to get the proposal estimated accurately. This is where you will incur a small fee for the builder to make his inspection and put together the price and specification.
Two weeks later
We lodge the development application (DA) with council or the complying development certificate (CDC) with a private certifier after final amendments have been completed on the drawing.
Three to five weeks later
It generally takes around 3 weeks for a CDC and 6 weeks for a DA to go through for a home extension. We’ll be in touch with you on receipt of the approval and present you with a formal written building contract. This is to be signed by both parties, at which stage we require a payment of 5% of the quoted amount which pays for the costs of getting the approval.
Within the next month
Add-Style will commence work on your home extension usually within two to four weeks of both parties signing the formal written building contract.
