Sydney’s built environment is shaped by architects who understand the city’s particular mix of heritage constraints, coastal conditions, and a client base with high expectations. Whether you’re planning a residential renovation in the inner west, a new commercial fitout in the CBD, or a mixed-use development on the urban fringe, the architect you choose will define not just how a project looks, but how it performs, gets approved, and holds its value over time.
Finding the right firm is not straightforward. Sydney has hundreds of registered architects, from sole practitioners to large studios with international footprints. The firms listed here were selected based on a combination of factors: demonstrated project quality across residential and commercial typologies, client review ratings, breadth of experience, and reputation within the industry. Where ratings are available, they reflect aggregated client feedback and are noted for each firm.
This list covers fifteen of Sydney’s strongest architectural practices for 2026, ranked to give you a clear starting point, whether you’re a homeowner looking for a sensitive renovation or a developer commissioning a large-scale build.
1. Luigi Rosselli Architects
Four decades of residential and commercial architectural design in Sydney
Luigi Rosselli Architects has been practising in Sydney for over forty years, building a portfolio that spans residential, commercial, and mixed-use projects across the city and beyond. The firm is known for a design approach that draws on materiality, craft, and a confident architectural language that tends to age well rather than date quickly.
With a rating of 4.3 out of 5, the practice has maintained strong client satisfaction over a long operating history, which is a meaningful signal for a firm of this scale and tenure. Their residential work in particular has attracted significant attention, with projects published widely in Australian and international architecture media.
The studio’s longevity gives it a depth of experience with Sydney’s planning systems, council requirements, and site conditions that newer practices simply cannot replicate. For clients looking for a firm that can handle complexity and deliver considered design, Luigi Rosselli Architects is a credible first call.
Pros
- Four decades of experience across residential and commercial typologies
- Strong design identity with published, award-recognised work
- Deep familiarity with Sydney’s planning and approval environment
- Consistent 4.3/5 client rating across a long operating period
Cons
- Scale and reputation may mean longer lead times for new commissions
- Design-led approach may not suit clients seeking a more pragmatic or cost-driven brief
Best for: Homeowners and developers seeking an experienced Sydney firm with a strong design reputation and extensive residential and commercial project history.

2. Those Architects Sydney
A Sydney practice focused on residential and commercial design outcomes
Those Architects Sydney operates as a focused architectural practice with a clear remit across residential and commercial design. The studio takes a considered approach to each project, working closely with clients to develop outcomes that reflect the specific conditions of the site and the brief rather than applying a one-size approach.
No aggregated rating is currently available for this practice, which makes direct comparison with rated firms harder. That said, the absence of a rating does not reflect poorly on the studio, and prospective clients would benefit from requesting references or reviewing portfolio work directly to assess fit.
For clients who want a practice that takes the brief seriously and works collaboratively from concept through to delivery, Those Architects Sydney is worth considering, particularly for residential projects where close communication between client and architect is most important.
Pros
- Focused scope across residential and commercial design
- Client-centred approach with emphasis on design intent
- Sydney-based with local site and planning knowledge
Cons
- No publicly aggregated client rating available for independent comparison
- Less publicly visible project history compared to larger or longer-established firms
Best for: Clients seeking a smaller, responsive Sydney practice for residential or commercial design projects where direct communication is a priority.

3. PTW Architects
A Sydney architecture firm with broad experience across commercial, residential, and mixed-use projects
PTW Architects is one of Sydney’s longer-established firms, with a history that extends back over a century. The practice has delivered projects at significant scale across Australia and internationally, covering commercial, residential, mixed-use, and hospitality sectors. Their portfolio includes landmark projects that have shaped parts of Sydney’s built landscape.
Rated 4.3 out of 5, PTW brings the credibility of a large and experienced studio alongside the systems and resources needed to manage complex, multi-stakeholder projects. The firm is particularly well regarded for its work in the sports and aquatics sector, having designed the Sydney Olympic Park Aquatic Centre and similar facilities internationally.
For clients with large or complex briefs, PTW offers the project management depth and design capability to match. Smaller residential clients may find the firm’s scale works against close personal engagement, so fit is worth considering carefully.
Pros
- Century-long operating history with deep institutional knowledge
- Strong track record in commercial, mixed-use, and large residential projects
- International reach with a grounded Sydney presence
- 4.3/5 client rating across a diverse project base

The firm’s design philosophy places emphasis on architecture that responds to context, community, and long-term performance.
With a rating of 4.8 out of 5, COX sits near the top of this list in terms of client satisfaction and is one of the standout performers across both quality of work and client experience. The practice has completed work across education, health, justice, sport, transport, and urban design in addition to its core commercial and residential output.

5. Sydney Architect Group
A Sydney architectural practice with a perfect client satisfaction record
Sydney Architect Group delivers residential and commercial architectural services across Sydney, maintaining a 5.0 out of 5 client rating that reflects consistent satisfaction across their client base. The practice works across the full project lifecycle, from initial concept and design development through to documentation, approval, and construction administration.
A perfect rating is notable, though it typically reflects a smaller or more selective client base rather than a firm operating at the volume of Sydney’s largest studios. That can be an advantage for clients who want direct engagement with the principal architect and a practice that manages its workload carefully.
For homeowners and smaller commercial clients who want reliable design outcomes and strong communication throughout the project, Sydney Architect Group is worth a close look.
Pros
- 5.0/5 client rating across reviewed projects
- Full-service delivery from concept through to construction administration

Crush Architecture delivers residential and commercial architectural design in Sydney, carrying a 5.0 out of 5 client rating that reflects strong performance across their reviewed commissions. The studio brings a contemporary design sensibility to its projects while maintaining a practical focus on buildability, budget, and approval outcomes.
The firm’s approach suits clients who want a clear design vision without losing sight of the practical realities of getting a project built. This balance between design ambition and pragmatic delivery is something many clients find difficult to locate in Sydney’s architecture market, where firms often skew toward one end or the other.
Crush Architecture is a good option for clients at both ends of the project scale, from residential alterations and additions to new commercial builds, particularly where design quality and client communication are priorities.
Pros
- 5.0/5 client rating across residential and commercial projects

The firm’s geographic reach beyond the Sydney metro is useful for clients with sites in regional New South Wales who want an architect with both city experience and an understanding of the practical realities of building outside the urban core.

Rated 4.5 out of 5, Grimshaw brings international design rigour alongside practical experience delivering complex, publicly visible projects. The firm is particularly associated with transport infrastructure and large civic builds, making it a distinctive choice compared to most of the other practices on this list.

A Sydney studio specialising in residential and commercial design with a focus on materiality and craft
Koichi Takada Architects has developed a recognisable design language centred on natural materials, biophilic principles, and a craft-driven approach to form. The studio operates across residential and commercial typologies, with a portfolio that includes significant residential towers, hospitality projects, and cultural commissions in Sydney and internationally.
The practice holds a rating of 3.6 out of 5, which sits below many of the other firms on this list. That rating may reflect the nature of large-scale, multi-party commissions where client experience is shaped by more factors than design intent alone. Prospective clients should weigh the rating against the publicly available portfolio, which is strong in design terms.
For clients whose priority is architectural distinctiveness and a strong design vision, particularly across high-end residential and hospitality projects, Koichi Takada Architects has a portfolio worth reviewing carefully.
Pros
- Distinctive design identity with strong materiality and biophilic focus
- Published work across high-end residential, hospitality, and commercial sectors
- International project exposure alongside a Sydney base
Cons
- 3.6/5 rating is the lowest on this list and warrants direct inquiry before engagement
- Design-forward approach may not suit clients with tightly constrained budgets or highly prescriptive briefs
Best for: Developers and high-end residential clients seeking a distinctively designed outcome in hospitality, luxury residential, or cultural sectors.

The firm holds a 5.0 out of 5 client rating and has consistently delivered work that sits at the intersection of social purpose and design quality.
The practice has a strong research culture that informs its design work, making it particularly effective on complex briefs where evidence-based design approaches add measurable value.

The practice holds a 4.9 out of 5 rating, placing it among the strongest performers on this list in terms of client satisfaction.
The combination of two decades of local experience and a near-perfect rating is a meaningful indicator of a firm that manages client relationships well across the full project arc, from briefing through to completion.

Lockhart-Krause Architects is a Sydney-based practice delivering residential and commercial architectural services with a 5.0 out of 5 client rating. The firm has built its reputation on close client engagement and design outcomes that reflect a genuine response to each brief and site rather than a house style applied across projects.
A consistently perfect rating across multiple reviews points to a practice that manages expectations well, communicates clearly, and delivers to brief.

Who is the best architects in Sydney?
Based on client ratings and project quality, COX Architecture (4.8/5), BVN (5.0/5), MCK Architects (4.9/5), and Luigi Rosselli Architects (4.3/5) stand out as some of Sydney’s strongest architectural practices. The right answer depends on your project type. COX and BVN are stronger for large commercial and civic briefs. Luigi Rosselli Architects and MCK Architects are well regarded for residential and mixed-use commissions. For smaller residential projects, studios like Crush Architecture, Lockhart-Krause, and Studio.SC carry perfect client ratings and offer more direct engagement.
How much does a architect cost in Sydney?
Architect fees in Sydney typically range from 8% to 15% of the total construction cost for a full-service engagement covering design, documentation, and construction administration. For smaller residential projects, some architects charge on a fixed-fee or hourly basis instead. Hourly rates generally fall between $150 and $300 depending on the principal’s experience and the firm’s scale. Fees for large commercial or civic projects may be structured differently, often negotiated based on scope and deliverables. Always request a written fee proposal that specifies what is included at each project stage before committing.
How do I choose a architect in Sydney?
Start by looking at published work. If a firm’s portfolio does not include projects similar in type, scale, or context to yours, that is a signal to look elsewhere. Ask about who will manage your project day to day, since in larger firms the principal who presents may not be the person running your job. Check whether the firm has experience with your local council and its specific planning controls. Request references from recent clients on similar projects, and ask those referees directly about communication, fee management, and delivery against programme. Fit matters as much as credentials on a project where you will be working closely with a team for months or years.
What should I look for in a architect?
Registration is the baseline. All architects practising in NSW must be registered with the NSW Architects Registration Board. Beyond that, look for demonstrated experience in your project type, a clear design approach you find genuinely compelling, and evidence of strong client communication. Ask to see projects at a similar budget to yours and find out what the final construction cost was compared to the initial estimate. Cost management and planning approval rates are practical indicators that are more useful than design awards alone. Professional indemnity insurance is also non-negotiable.
Are there good architects for small businesses in Sydney?
Yes. Several firms on this list work well at the smaller commercial scale. Crush Architecture, Sydney Architect Group, Lockhart-Krause Architects, Darkside Architecture Studio, and Studio.SC all carry strong client ratings and work across residential and smaller commercial commissions. These studios tend to offer more direct principal involvement and more flexible engagement structures than larger practices. JS Architects is also worth considering for businesses located in regional NSW as well as metropolitan Sydney. For fitouts, retail, or office design where budget and programme discipline are critical, choosing a firm with demonstrated experience at your project scale is more important than overall firm reputation.
Sydney has a genuinely strong pool of architectural talent, from small studios with perfect client ratings to nationally recognised practices with decades of major project delivery behind them. The firms on this list cover a wide range of scales, sectors, and design approaches, which means the best choice for your project will depend on factors specific to your brief, site, budget, and how you want to work with your architect. Use ratings as a starting point, review portfolios carefully, and speak to multiple firms before making a decision. Architecture is a long-term relationship with significant financial and practical consequences, and the time spent finding the right fit at the outset pays off considerably over the course of a project.
