Alterations & Additions — Northern Beaches Building Designer
Home Extensions & Alterations — Northern Beaches Building Designer, Mona Vale
Extending your Northern Beaches home is one of the smartest investments you can make. We design extensions that work with your home's character and get through approval cleanly — DA or CDC.
Crafting Exceptional Living Spaces
Alterations and additions are the most common residential project type on the Northern Beaches and for good reason. The Northern Beaches property market rewards well-designed, approved improvements. A ground-floor extension, a first-floor addition, a new deck done right, these projects add more value than they cost.
Northern Beaches Designs handles the complete design and approval process for alterations and additions across all Northern Beaches suburbs. We've designed extensions in Paln Beach, Avalon, Mona Vale, Queenscliff, Newport, North Narrabeen, Bayview, and across the LGA and we know what each suburb's planning controls require.

WHICH APPROVAL PATHWAY CDC OR DA?
Understanding the approval process is crucial for a smooth project journey. At Northern Beaches Designs, we guide you through two main pathways:
- Complying Development Certificate (CDC): A streamlined process for straightforward projects. It requires less time and involves fewer steps, making it ideal for projects that meet specific criteria.
- Development Application (DA): This pathway is necessary for more complex projects. It involves a detailed assessment by the local council, ensuring that all aspects of the design comply with local planning regulations.
Common Questions About Home Extensions
Explore our most frequently asked questions about home extensions and alterations to help guide your renovation journey.
Do I need approval to extend my Northern Beaches home?
Most significant extensions require either a CDC or DA. Some minor works may qualify as exempt development under SEPP (Exempt and Complying Development Codes) 2008. Internal works (no structural changes, no increase in floor area) may not require any approval. We advise on the correct path for your specific works at the initial consultation..
Can I add a second storey to my existing home?
In most cases, yes subject to the LEP height limit (typically 8.5min R2 zones), DCP controls on bulk and scale, and setback requirements. First floor additions that respect these controls can often proceed via CDC. We assess this for your specific property.
How much does an extension cost to design and approve on the Northern Beaches?
Design and approval fees depend on the scope of works. For a straightforward ground floor extension via CDC, our fees are fixed-price and typically cover concept, CDC documentation, and lodgement. DA projects are priced in stages. We provide a written fee proposal after the initial consultation.
I have an unapproved deck/extension. What can I do?
You can seek retrospective (regularisation) approval through a DA with Northern Beaches Council. The structure is assessed against current planning and building controls. Some unapproved works can be regularised straightforwardly; others may require modification or, in some cases, demolition. We assess retrospective approval feasibility as part of our initial consultation.
How do I choose the right design for my extension?
Choosing the right design involves considering your lifestyle needs, budget, and the existing style of your home. Our team can help guide you through this process to ensure a seamless integration.
