High-end renovations, extensions and pre-construction advisory — delivered with clarity, planning and craftsmanship.
Leederville, Perth
High-end renovations, extensions and pre-construction advisory — delivered with clarity, planning and craftsmanship.
Led by Founder & Director Andrew Craster, Crastyle Builders was built on a simple belief — residential renovations and extensions should be transparent, well-planned, and professionally managed from start to finish.
A carpenter by trade with 23 years of industry experience, Andrew has built Crastyle Builders around the kind of process homeowners actually need when undertaking high-value renovation and extension projects: honest advice, clear communication, and proper planning before construction begins.
We are not a volume builder. We specialise in high-end renovations, extensions, and bespoke residential building work, delivering projects with a strong focus on detail, craftsmanship, and client experience.
By prioritising pre-construction planning, detailed scoping, and transparent communication, we help clients reduce uncertainty, avoid costly surprises, and move into construction with clarity and confidence.
At Crastyle Builders, we specialise in high-end renovations, extensions, and pre-construction planning — delivered with a strong focus on craftsmanship, clarity, and client experience.
Transform your existing home with carefully planned renovations designed to improve functionality, lifestyle, and finish.
Seamless additions designed to create more space while integrating naturally with your existing home.
High-end kitchen and bathroom renovations delivered with a focus on layout, detail, and premium finishes.
Detailed planning and builder input to ensure your project begins with clarity, confidence, and a properly defined scope.
Why rushed quotes often lead to expensive mistakes.
At Crastyle Builders, we believe the success of any renovation or extension is determined long before construction begins.
Many plans look good on paper but aren't fully reviewed for cost, buildability, scope, and budget alignment, which often leads to confusion, unrealistic expectations, and higher-than-expected pricing at the quoting stage.
Too often, homeowners receive quick, free quotes based on incomplete plans and rough assumptions. While appealing initially, this often leads to budget overruns, unclear scope, and costly surprises once construction is underway.
Our Pre-Construction Advisory service provides a paid, detailed review of your plans, scope, site conditions, buildability, and cost drivers. We identify potential issues early and offer structured builder input — helping you make informed decisions, set clear expectations, and ensure your project is properly aligned before construction begins.
Clearer scope and fewer surprises during construction.
Identify issues early before they become costly on site.
Builder-led advice to help you move forward with confidence.
"Designed to protect your budget before construction begins."
We begin by understanding your goals, budget, and vision to determine whether your project is the right fit for Crastyle Builders.
We review your plans, scope, and project requirements in detail to identify risks, assess buildability, and provide early builder input.
We develop a clear scope of works and detailed pricing framework so you understand exactly what is included before construction begins.
Once scope and pricing are finalised, we move into formal documentation, contract preparation, and project readiness so everything is clearly defined before works commence.
With planning and approvals complete, we move into construction with a strong focus on communication, quality workmanship, and a smooth final handover.
At Crastyle Builders, most of our projects are delivered under a structured fixed price contract, providing clarity, control, and confidence before construction begins. Depending on your project and level of flexibility required, we also offer cost plus and project management pathways where appropriate.
A flexible delivery model where you pay the actual cost of construction plus an agreed builder's margin. This approach is best suited to projects where scope, selections, or design details are still evolving, allowing greater flexibility during construction while maintaining transparency around costs.
A structured contract where scope, selections, and pricing are clearly defined before construction begins. This is our preferred approach for most renovation and extension projects, allowing clients to move forward with confidence, knowing exactly what is included.
We manage and coordinate your project on your behalf, overseeing trades, scheduling, and overall delivery while you engage subcontractors directly. This approach is best suited to clients who want experienced builder oversight and professional coordination throughout the project.
We take the time to properly assess each project before pricing, helping reduce costly surprises later.
Detailed scope and transparent pricing so clients understand exactly what is included before construction begins.

Founder & Director
"The best building projects are built twice — first through planning, then on site."
A carpenter by trade, Andrew Craster has spent the past 23 years working across the residential construction industry, beginning his apprenticeship at just 15 years old. He founded Crastyle Builders to give clients a better building experience — one built on professionalism, transparency, and proper planning from the outset.
Specialising in renovations, extensions, and bespoke residential building work, Andrew created Crastyle Builders in response to the rushed quoting, poor communication, and lack of preparation that too often impacts residential projects.
His approach is centred around strong pre-construction planning, honest advice, and clear communication from day one. By taking the time to properly understand each project before work begins on site, Andrew helps clients avoid costly surprises, reduce unnecessary stress, and achieve a final result that reflects their vision.
At Crastyle Builders, every project is approached with the care, detail, and planning required to deliver a result clients can be proud of.
"To say Andy went above and beyond with our renovation would be an understatement. We had Crastyle Builders complete our kitchen, dining and laundry renovation on our house and we couldn't be happier. We loved working with Andy throughout - he was always transparent, communicated often so we always knew what was going on and so accommodating. His attention to detail and pride in his work didn't go unnoticed. Thanks so much Andy and the Crastyle Builders team - we will be recommending you always!"Steven and Steph Wityk. Bayswater, Perth
"High quality, friendly and professional. Andy and his team helped us restore the facade of our house and made our front porch usable again. Andy was so respectful of our home and space, always leaving a tidy site and making sure things were safe. He was very aware of the fact that we have a young family and made a big effort to make sure we weren't inconvenienced for too long. Andy was easy to communicate with and also very focused on providing a high quality build as were all of the trades he bought in. We are so happy that we chose Crastyle builders and would definitely work with them again. Thanks Andy!"Mike and Abby Mosedale. North Perth
"Andy finished my house after my first builder went into administration leaving an unfinished shell. He put right all the defective works, had a high standard of trades working with him and paid attention to details. He took pride in getting a good outcome for me and my family. I would recommend Andy to anyone considering a new build, reno or trying to find a builder to help finish another contractor's mess. He was also reasonable and didn't over charge me and was completely flexible with small variations up to the end of the build. We are now in defects period and only have a handful of outstanding items which is shows his attention to detail."Phillip Kingston & Jane Redford. Carlisle, Perth
At Crastyle Builders, we don't believe in rushed or guess-based quoting. Instead, we offer a structured Pre-Construction Advisory service, where we properly review your plans, scope, and project requirements before pricing.
This allows us to provide clear, accurate costings and identify potential risks early — helping you avoid costly surprises during construction. It's a more professional approach that protects both your budget and your project outcome.
Pre-Construction Advisory is a detailed planning and review process completed before construction begins.
We assess your plans, scope, site conditions, and buildability, and provide builder-led input to ensure your project is properly aligned with your budget and expectations.
This stage is key to delivering a well-structured, predictable build and is a core part of how we operate at Crastyle Builders.
For most renovation and extension projects, we recommend a fixed price contract once the scope and documentation are fully defined.
This provides clarity, cost certainty, and a structured building process.
We also offer cost plus and project management options where greater flexibility is required, and we guide each client toward the most suitable approach based on their project.
Timeframes vary depending on the size, complexity, and level of planning involved in each project.
A well-planned project will always run more efficiently, which is why we place strong emphasis on pre-construction planning before work begins on site.
During the early stages, we provide realistic timelines so you understand what to expect throughout the build.
Yes, however changes during construction can impact cost, timeline, and overall project flow.
Our process is designed to minimise the need for variations by ensuring key decisions are made during the planning stage.
Where changes are required, they are managed in a structured and transparent way so you remain fully informed throughout the process.
Contact us today to discuss your vision and discover how our structured approach delivers superior results.
Whether you have completed plans or are just starting to explore your options, we're here to help guide you through the process. At Crastyle Builders, we take a planning-first approach to ensure your project is properly considered before construction begins.
