Heritage Extensions Projects

Our Heritage Design Portfolio

Examples of our approved and built heritage DA projects are shown below. These projects demonstrate how older homes can be carefully adapted for modern living while respecting their original character, streetscape presentation and heritage planning requirements.  Our heritage work includes rear additions, upper-storey additions, internal reworking and contemporary extensions behind original façades.

 

Several of these projects have also received industry design awards, reflecting the care, detail and design resolution involved in adapting older homes for contemporary living.

How We Design Heritage Extensions & Renovations

Heritage Homes Adapted for Modern Living

A well-designed heritage renovation should improve space, comfort and everyday liveability while respecting the original home and its streetscape setting.  We design renovations and extensions for homes within Heritage Conservation Areas and individually heritage-listed properties across Sydney.

Why Early Investigation Matters

 

Heritage controls, site constraints and likely documentation requirements should be reviewed before the design progresses too far.

We assess the relevant council controls early, identify potential issues and coordinate input from a qualified heritage consultant. This helps establish a practical design direction and reduces the risk of unnecessary redesign.

Award-Winning Heritage Design

 

Heritage requirements do not prevent good design. An addition may reflect the character of the original home or take a more contemporary approach behind the existing façade, depending on the property and council controls.

 

With more than 30 years of residential design experience, including extensive work across Sydney’s Inner West, our heritage projects have been recognised for their design resolution, care and attention to detail.

What Our Heritage Design Services Includes

Heritage Site Review

We assess your property’s heritage status, streetscape context, council controls, site constraints and existing building fabric to identify the most appropriate approval pathway early in the project.

Heritage Renovation & Extension Design

We design rear additions, upper-storey additions and internal alterations that respect the original home while improving natural light, space and functionality.

Architectural Drafting & Documentation

We prepare detailed floor plans, elevations, sections, roof plans, shadow diagrams and material notes for council assessment and consultant review.

Council Liaison & DA Documentation

We prepare and coordinate the technical documentation for your development application, manage the NSW Planning Portal lodgement within our agreed scope and respond to relevant planning and heritage matters during the assessment process.

Heritage Consultant Coordination

We coordinate the required input from heritage consultants, planners, engineers, BASIX assessors and surveyors, helping align the design and supporting documentation with the Statement of Heritage Impact and other consultant requirements.

Buildable Heritage Design

We balance heritage character with construction practicality, protecting the original streetscape while improving privacy, natural light, functionality and everyday liveability.

Interior Detailing & Finishes Packages

For comprehensive heritage renovations, we offer optional interior detailing. This helps align new kitchens, bathrooms, laundries, joinery and finishes with the character of the existing home, supporting a cohesive result and clearer builder pricing.

Heritage Extensions FAQs

Do I need a specialist heritage architect for my project?

Not necessarily. Distinct Innovations prepares the building design and technical drawings, while an appropriately qualified and experienced external heritage consultant prepares the required Statement of Heritage Impact. We coordinate this report, along with any other required specialist reports and documentation, as part of the DA process.

Will council allow a modern rear extension to a heritage home?

A contemporary rear extension may be acceptable where it responds appropriately to the property’s heritage significance. Council will consider matters such as scale, form, materials, visibility from the street and the relationship between the new and existing building.

Will I need to retain the original front façade?

In many heritage projects, the street-facing façade and other significant original features are expected to be retained. The extent of permissible change depends on the property’s heritage significance, the applicable planning controls and council’s assessment.

Planning a heritage extension project?

Every heritage property has different constraints, opportunities and approval requirements. We can review your home, discuss the changes you are considering and explain the likely design, consultant and DA documentation requirements before you proceed.
