At Planshop, we provide architectural design, drafting, town planning, project management and on-site architectural presence for homeowners across Sydney’s Lower North Shore, from Mosman, Beauty Point and Clifton Gardens to Hunters Hill, Woolwich, Lane Cove, Longueville, Riverview, Northbridge and Castle Cove.
Led by Nominated Architect Martin Taylor with 20+ years of experience, we work on Federation home restorations, harbour-foreshore renovations, heritage estates, contemporary additions and ground-up new builds across the four councils that govern the Lower North Shore: Mosman Council, Lane Cove Council, Hunters Hill Council and Willoughby City Council.
Our integrated design-to-construction model means an architect-led team takes your project from first sketch through to final inspection, with daily focus and on-site attendance throughout the build.
Architectural Design and Construction on the Lower North Shore
The Lower North Shore is one of Sydney’s most architecturally protected residential regions. Encompassing approximately 35 suburbs across four council areas, the region stretches from the Lane Cove River in the west to Middle Harbour in the east, and from the Sydney Harbour Bridge in the south to the boundaries of Willoughby and northern Lane Cove. It is defined by harbour and waterway frontage, mature canopy, Federation and California Bungalow housing stock, and some of the most extensive local heritage protection in Greater Sydney.
Mosman Council alone administers approximately 500 heritage items and 13 Heritage Conservation Areas listed under the Mosman LEP 2012. Hunters Hill is one of Australia’s oldest continuously inhabited suburbs and retains a remarkable concentration of 19th-century stone cottages, Italianate villas and Federation homes, most of them heritage-listed. Willoughby and Lane Cove also maintain extensive heritage schedules across their leafy suburban streets.
This is a region of established family wealth. Hunters Hill and Woolwich rank among Australia’s highest-earning postcodes with average household incomes around $215,000, and Mosman’s median house price sits around $5M with harbour-side homes routinely exceeding $10M. Residents are predominantly multi-generational professional and finance families who chose the area for the harbour setting, the schools, the canopy and the architectural character, and who want their homes to reflect those priorities.
Most Lower North Shore projects fall into one of three categories: Federation and Inter-War heritage home restorations and extensions, contemporary harbour-foreshore new builds and major remodels, or sympathetic additions to California Bungalows and post-Federation family homes. Each demands a different design approach and different on-site coordination. This is the work Planshop specialises in. See examples of our heritage and harbour-side work in Our Work.
Why Lower North Shore Homeowners Choose Planshop
Architectural presence that protects heritage and investment
Lower North Shore renovation budgets routinely exceed $2M, often considerably more. A great design alone does not protect that investment, particularly on heritage-listed sites where small build decisions can compromise the approval, the heritage values and the finished result. Most Sydney architects step back once the DA is approved, leaving the build to contractors and certifiers. Martin Taylor and the Planshop team can remain on the project, including on site, throughout construction, assisting the coordination of trades, resolving issues in real time, and protecting design intent and heritage integrity. Read more about how our on-site architectural engagement works.
Experience across all four Lower North Shore councils
Mosman, Lane Cove, Hunters Hill and Willoughby each operate under their own LEP and DCP, with different heritage schedules, harbour-foreshore controls and assessment approaches. We have prepared and lodged applications across all four. Mosman LEP 2012 governs one of Australia’s most heritage-protected LGAs. Lane Cove LEP 2009 and Willoughby LEP 2012 each have their own heritage and design control frameworks. Hunters Hill’s LEP protects the village character that has made it one of Sydney’s most distinctive enclaves. Knowing which Council assesses your application, and how, is the first step. Learn more about our town planning services.
Federation, Inter-War and California Bungalow expertise
The Lower North Shore’s dominant housing stock includes Federation homes, Inter-War residences, California Bungalows, Italianate villas in Hunters Hill, and a smaller proportion of mid-century and contemporary new builds. Each typology requires a different design approach to a renovation or extension, with different structural conditions, original-fabric sensitivities and streetscape obligations. We bring direct experience of all of these typologies and the councils that assess them.
An integrated in-house team
Architect, drafting, town planning and project management all sit within one practice. There is no handover between consultants, no gaps in the documentation, and no finger-pointing when a detail needs resolving. For multi-year heritage projects coordinating heritage consultants, landscape architects, interior designers, structural engineers and specialist builders, this single point of accountability matters. See our full range of services.
Our Services for Lower North Shore Projects
Architectural Design
Concept through to construction documentation for heritage restorations, contemporary extensions, harbour-foreshore new builds and ground-up family homes across the Lower North Shore. Our designs respond to heritage streetscapes, mature canopy, sloping topography, harbour and waterway views, and the design expectations of a generationally embedded clientele.
Architectural Drafting
Construction-ready drawings prepared to NCC and BASIX standards, with the level of detail Mosman, Lane Cove, Hunters Hill and Willoughby Council assessors expect. We produce drawings that high-end builders can price accurately and build from cleanly, reducing variations and rework during construction.
Town Planning
Statement of Environmental Effects, Heritage Impact Statements, Conservation Management Plan submissions, foreshore variance applications, BASIX certificates, and Clause 4.6 variation requests when development standards need negotiating. We prepare the planning case upfront so applications move through Council assessment without unnecessary requests for additional information.
Project Management
Coordination of structural engineers, certifiers, heritage consultants, landscape architects, interior designers, surveyors and builders from the design phase through to handover. One project manager, one schedule, one budget tracked across the full project lifecycle.
On-Site Architectural Presence
This is what sets Planshop apart. We can be on site throughout construction, not on a fortnightly inspection schedule, but as part of the build team. Using BIMx, we coordinate live with builders and trades on the model itself, resolving detail questions immediately rather than letting them become defects, variations or finish-quality issues at handover.
Working with Lower North Shore Councils
Each Lower North Shore council operates differently, and a well-prepared application reflects that.
Mosman Council
Mosman Council administers an LGA of approximately 8.7 square kilometres covering Mosman, Beauty Point, Balmoral, Clifton Gardens, Georges Heights, Spit Junction, Cremorne Junction and The Spit. The Mosman LEP 2012 protects approximately 500 heritage items and 13 Heritage Conservation Areas, making it one of Australia’s most extensively heritage-controlled LGAs. Significant DAs are typically determined by the Mosman Local Planning Panel. Realistic timeframes are 14 to 20 weeks for standard residential DAs and 18 to 28 weeks for heritage-listed properties.
Hunters Hill Council
Hunters Hill Council, one of Sydney’s smallest and oldest councils, covers Hunters Hill, Woolwich, Henley, Huntleys Point and Gladesville (in part). The Hunters Hill LEP and DCP protect one of Australia’s most intact 19th-century residential streetscapes, including the stone cottage and Italianate villa fabric that defines the area. Council scrutiny on alterations and additions in heritage areas is significant. Realistic timeframes are 14 to 20 weeks for standard residential DAs.
Lane Cove Council
Lane Cove Council covers Lane Cove, Lane Cove West, Lane Cove North, Linley Point, Longueville, Northwood, Greenwich, Riverview and parts of Artarmon and St Leonards. The Lane Cove LEP 2009, recently amended to reflect the St Leonards and Crows Nest 2036 Plan in the southern part of the LGA, governs a mix of Federation and Inter-War stock with newer infill. Realistic timeframes are 12 to 18 weeks for standard residential DAs.
Willoughby City Council
Willoughby City Council covers Chatswood, Willoughby, Naremburn, Castlecrag, Northbridge, Castle Cove, Middle Cove, Artarmon (in part) and Roseville (in part). The Willoughby LEP 2012, also amended for the St Leonards and Crows Nest 2036 Plan, governs a mix of Federation, Inter-War, California Bungalow and post-war suburban stock with significant heritage and bushland controls in the Castlecrag and Northbridge areas. Realistic timeframes are 12 to 18 weeks for standard residential DAs.
Common DA challenges across the Lower North Shore include:
- Heritage Conservation Areas: extensive HCAs across Mosman, Hunters Hill, Northbridge, Castlecrag and parts of Lane Cove. Front-of-house and visible roofscape changes face strict scrutiny, and Heritage Impact Statements are required for most works.
- Harbour and waterway foreshore controls: the Sydney Harbour Foreshore SEPP and the council-specific DCPs impose strict controls on developments affecting Sydney Harbour, Middle Harbour, Lane Cove River and Parramatta River frontage.
- View-sharing: on the Lower North Shore’s steep harbour-adjacent blocks, view-sharing assessments under the Tenacity Consulting v Warringah Council principles are routinely contested by neighbours and assessors.
- Tree and canopy protection: mature canopy trees are heavily protected across all four councils, particularly in Castlecrag (Walter Burley Griffin legacy), Northbridge, Hunters Hill and the heritage parts of Mosman. Removal or significant pruning requires separate consent.
- Distinct LEPs across four councils: Mosman LEP 2012, Lane Cove LEP 2009, Hunters Hill LEP, and Willoughby LEP 2012 each apply differently. Confirming the correct consent authority and applicable controls is the first step in any project.
- Specialist heritage advisors: Mosman and Hunters Hill in particular use specialist heritage advisors at the assessment stage, who scrutinise material specification, joinery, glazing and roofscape decisions in detail.
We prepare every application knowing which Council assesses it and how, which avoids the most common cause of delay, that is, applications that get sent back for additional information.
Common Project Types on the Lower North Shore
- Federation home renovations and extensions: comprehensive renovations of Federation residences in Mosman, Hunters Hill, Lane Cove and Willoughby, restoring period detail while reconfiguring for contemporary family life.
- Heritage estate restorations: significant heritage-listed properties in Mosman’s HCAs and Hunters Hill’s 19th-century village streets, requiring Conservation Management Plans and specialist heritage advisor coordination.
- Harbour-foreshore new builds and major remodels: in Mosman, Beauty Point, Clifton Gardens, Balmoral, Woolwich, Longueville, Northbridge and Castle Cove, navigating Sydney Harbour Foreshore SEPP controls and view-sharing requirements.
- California Bungalow renovations: common in Willoughby, Lane Cove, Naremburn and parts of Mosman, opening rear living spaces while respecting the original front-of-house character.
- Walter Burley Griffin precinct work: Castlecrag retains a significant collection of Griffin-designed and Griffin-era homes that require particular sensitivity to streetscape, bushland and original architectural character.
- Pool houses, cabanas and garden pavilions: ancillary structures within heritage and harbour-foreshore controlled sites.
- Sloping-site renovations: harbour-adjacent and gully-side blocks throughout Mosman, Hunters Hill, Northbridge and Castle Cove that require integrated site engineering from the design stage.

Frequently Asked Questions
Can I renovate a Federation or heritage home on the Lower North Shore?
Yes, in most cases. Heritage listing or Heritage Conservation Area inclusion does not freeze your home, it controls how changes are made. Rear extensions, internal reconfigurations and sympathetic additions are routinely approved when they respect the original streetscape, roof form and significant fabric. Front facades and roof changes visible from the public domain face the strictest assessment, particularly in Mosman and Hunters Hill. A Heritage Impact Statement is generally required for any DA within an HCA, and we prepare these as part of our integrated service.
Which council covers my Lower North Shore property?
It depends on the suburb. Mosman Council covers Mosman, Beauty Point, Balmoral, Clifton Gardens, Georges Heights and The Spit. Hunters Hill Council covers Hunters Hill, Woolwich, Henley and Huntleys Point. Lane Cove Council covers Lane Cove, Longueville, Northwood, Greenwich, Riverview, Linley Point and Lane Cove North. Willoughby City Council covers Chatswood, Willoughby, Naremburn, Castlecrag, Northbridge, Castle Cove and Middle Cove. Each council has its own LEP, DCP and heritage framework, and confirming the correct consent authority is the first step in any application.
How long does a Lower North Shore DA typically take?
It depends on the council and the complexity of the proposal. Lane Cove and Willoughby typically determine standard residential DAs in 12 to 18 weeks. Mosman and Hunters Hill are generally slower, at 14 to 20 weeks for straightforward DAs and 18 to 28 weeks for heritage-listed properties or HCA applications, partly because significant works are determined by Local Planning Panels rather than under delegated authority. A well-prepared application moves through assessment significantly faster than one missing supporting documentation.
Do I need a Heritage Impact Statement for my Lower North Shore renovation?
If your property is individually heritage-listed, or sits within a Heritage Conservation Area under Mosman LEP 2012, Hunters Hill LEP, Lane Cove LEP 2009 or Willoughby LEP 2012, a Heritage Impact Statement is generally required for any development application. Some minor maintenance and like-for-like repairs can proceed under a Heritage Exemption Certificate without a full DA. We assess heritage status as the first step of every project and identify which approval pathway applies before any design work begins.
What does a comprehensive Lower North Shore renovation typically cost?
Construction costs for Lower North Shore renovations and new builds typically run from $6,000 to $12,000 per square metre as of 2026, depending on heritage complexity, finish level, site access and the specification of joinery, stone, fittings and bespoke elements. Harbour-foreshore new builds and major heritage estate restorations frequently sit at the top of that range or above. Architect, drafting and planning fees on a typical $2M to $6M project traditionally sit at around 10 to 12% of construction cost when delivered as an integrated service with on-site roles through construction included.
We however base our fees on a stage-based approach to be highly competitive and challenge the above, adding transparency and client optioneering to target your investment exactly where you need it. Use our ‘GET A QUOTE’ service to find out more.
Can Planshop manage harbour-foreshore and view-sharing applications?
Yes. We have prepared applications under the Sydney Harbour Foreshore SEPP and the council-specific DCPs, including view-sharing assessments under the principles established in Tenacity Consulting v Warringah Council. View-sharing is one of the most contested planning issues on the Lower North Shore, particularly on the steep harbour-adjacent blocks of Mosman, Northbridge and Castle Cove. A well-prepared application addresses it head-on with view-loss diagrams, sectional studies and design responses that demonstrate reasonable view-sharing has been achieved.
What is on-site architectural presence and why does it matter for a heritage renovation?
On-site architectural presence means the architect remains involved through construction rather than simply handing the project to a builder after DA approval. For heritage renovations on the Lower North Shore this is often critical: original fabric is unpredictable, structural conditions vary from the drawings, and small build decisions can compromise both the heritage values and the design intent. At Planshop, Martin Taylor and the team can be on site throughout construction, coordinating with trades and resolving issues as they arise. This is the model we built the practice around.
Get Started
If you’re planning a renovation, extension or new build on the Lower North Shore, the first step is a consultation with Martin Taylor. We’ll review your property, confirm which council and which controls apply, and outline a realistic scope, timeframe and budget before any drawings are produced.
