Heritage home extensions in Orange and across NSW
Federation and Victorian homes
Heritage home extensions in Orange and across NSW
Adding a new wing to an old house is one of the most rewarding projects an architect can take on, and one of the easiest to get wrong. Source Architects designs heritage home extensions for Federation and Victorian houses from our studio at 146 Lords Place in Orange NSW. Our extension to March House, a 1910s Federation home, received AIA NSW Country awards for Interiors and for Alterations and Additions. David Sutherland (Registered Architect NSW 7572) and Sally Sutherland (Registered Architect NSW 7587) lead every project personally.

Why heritage home extensions need a different approach
Restoring a heritage home is about repair. Extending one is about adding something new that the old house can live with. The new work has to give a family the light, space and connection to the garden they want, while leaving the original house clearly readable, especially from the street.
Our approach is simple to describe and hard to do well. We keep the historic rooms intact where we can, place the new work where it causes least harm, usually at the rear, and let it be honestly contemporary rather than a copy of the old. A clear line between old and new is what heritage advice generally favours, and it usually makes the better house too. The result is a heritage home with a modern extension that feels like it belongs.
March House: a Federation home with a modern extension
March House is a 1910s Federation style house on one of Orange's best streets. The owners wanted a light filled, contemporary home for a young, growing family. We added a simple new form at the rear holding a new kitchen, dining and living space that looks over the back yard, with an internal courtyard that visually links the existing house to the new form.
The original house was completely restored, with new services and facilities carefully added. The project received AIA NSW Country awards for Interiors and for Alterations and Additions, a Commendation for Heritage, and an Orange City Council Heritage Award. A second stage, a garden pavilion with a garage, gym, indoor pool and sauna, followed later.
Extending Victorian and older homes
Several of our projects follow the same principles. At River House, a historic property on the banks of the Macquarie River, the owners have taken on the task of restoring a house that had not received much care. Our design, currently in design development, carefully inserts contemporary services and additional bathrooms into the existing structure and adds a new living and main bedroom wing that opens to the landscaped gardens.
Sadlier House, a substantial Victorian Italianate style country home from the 1870s, shows where a Victorian home extension can begin. We removed unsympathetic verandah infills and created new north facing living spaces that open to expansive new landscaped gardens.
Extensions in heritage conservation areas
Many older homes in Orange and other Central West towns sit inside heritage conservation areas, where council looks closely at anything new that can be seen from the street. Ellore is a good example: a property dating from 1910 on a heavily treed site within the Central Orange Conservation Area. Our design, currently pending approval, restores the existing house and adds new contemporary living and sleeping spaces for a growing family, with a direct connection to the landscaped yard.
We prepare the drawings and documents council needs, and we work with heritage specialists when an application calls for them, so the proposal is clear and well supported.
Heritage home extensions across NSW
Our studio is in Orange, and most of our heritage work is in and around the Central West, but we take on heritage home extensions across NSW where the project suits. Whatever the town, the process is the same: we visit the house, understand what makes it special, and design an extension it can live with for another hundred years.

Common questions about heritage home extensions
Can I extend a heritage listed home?
Usually, yes. Most heritage listed homes can be extended if the new work respects the significance of the original. Council approval is needed, and a well designed extension with clear documentation gives the application the best chance.
Should an extension copy the style of the old house?
Generally not. Most heritage guidance favours new work that is clearly of its time but sits comfortably with the original in scale, form and materials. A copy can blur what is genuinely historic.
What makes a good Federation home extension?
A good Federation home extension keeps the original rooms and street front intact, places new living spaces at the rear, and brings in light and a connection to the garden. March House in Orange is our best known example.
Do you also restore the original house?
Yes. Most of our heritage home extensions include restoring the original house, from repairing period details to carefully adding modern services and bathrooms.
Have your heritage home extensions won awards?
Yes. March House received AIA NSW Country awards for Interiors and for Alterations and Additions, a Commendation for Heritage and an Orange City Council Heritage Award.
