We’ll help you tackle the most important things in a renovation project. Lewis Building Design offers 3 special packages for all home renovations and extensions, created to suit every stage of your renovation journey.
If you’re looking for modern design and Town Planning assistance, our Signature package readies all your design and planning applications for your builder. For a full-service new home design, our Bespoke package includes coordinating with builders and managing your entire build from start to finish.
No matter your choice, we’re here to make your journey seamless.
The timeframe depends on your project’s scope and complexity. Design and permit submissions can take anywhere from 3 to 9 months, while construction can range from 3 months for minor renovations to 12+ months for large-scale extensions. Our team will provide a tailored timeline estimate in our initial meeting.
Yes, all structural renovations and extensions require a building permit. We can manage all necessary permit applications on your behalf.
This takes careful planning and detailing. We match roof pitches, use similar building materials, and select complementary colours and finishes so the new work feels like a natural extension of the existing home rather than an afterthought.
We have experience in using smart design principles, such as orienting windows to the north, introducing skylights, removing unnecessary internal walls, and increasing ceiling heights where possible. This improves both natural light and airflow, making the home more energy-efficient and comfortable.
Our goal is to make the renovation or extension journey as smooth as possible. We begin by exploring your ideas and needs, then develop detailed designs that incorporate the necessary permits to bring them to life. We will also coordinate with consultants and councils and guide you through the builder selection process. During construction, we’ll visit your site regularly to ensure your design vision is carried through.
We believe a great design considers both your lifestyle and the home’s long-term value. This means avoiding additions that look tacked-on, reducing wasted space, and improving flow throughout the home. For homeowners looking to sell, we also consider what the market is looking for, so that the renovation appeals to buyers.
