Award-Winning Integrated Architect-Builder Model

We are a full service, Class 1 and Class 2 architect and custom home builder, employing a creative process which is shaped with care, guided by expertise, and carried through with certainty.

Located in Freshwater on Sydney’s Northern Beaches, MILEHAM is a boutique architecture and custom construction firm specialising in residential homes. We provide integrated design and build services for discerning clients looking to renovate or rebuild, creating homes that unlock the true potential of their lifestyle and their property’s value.

Drawing on our passion for timeless, classic and proportional design, overlaid with extensive industry and technical knowledge across both architecture and construction, standalone and low-rise apartment properties, every home we create is not only finely crafted but also deeply personal – reflecting the lifestyle and aspiration of its owners.

Unlike most projects where the architect designs and the builder interprets, we hold both licences – ensuring your vision never gets lost in translation. From the first sketch to the final handover, our architecture, interior and construction teams work as one, keeping designs grounded in construction reality, budgets aligned and true to brief, and the overall process seamless.

A project which is looked after from concept to completion by the same team of professionals ensures project knowledge is retained and not lost between third parties (as can happen during traditional project handover from designer to builder). This approach ultimately protects project value and our client’s emotional wellbeing.

Our integrated approach is defined by care, certainty and a dedication to delivering homes that exceed expectations whilst giving our clients confidence and peace of mind at every step.

Our Process, Your Peace of Mind

Whether you engage MILEHAM for Design Only, Build Only, or the full Design and Build, every project benefits from the same level of care and expertise. You choose how you engage. The standard doesn’t change.

The Conversation That Starts It All
It starts with a phone call. We listen to what you’re hoping to achieve, learn about your home (what’s working, what’s not), and give you an honest initial sense of what’s possible.
Milestones
  • No obligation. No cost. Just a clear and open 15 minute conversation.
  • A deeper understanding of who we are, and how we work with our clients.
  • Honest guidance on how your scope, timeline and project investment align.
Framing the Vision Onsite
We visit your home to understand your site, the structure and the opportunity. This is where your project begins to take shape.
Milestones
  • A complimentary assessment of your property’s potential and constraints.
  • Initial discussion of design direction, planning pathway (DA or CDC)) and recommended construction investment.
  • Provision of a Fixed Price Design Proposal
  • You’ll walk away with a true understanding of timeline and investment to achieve your goals – or what an alternative solution could be.
Design That’s Drawn to be Built
Our architecture team leads the design. Interior selections – materials, finishes, joinery and lighting – are developed as an integrated part of the process, not a separate phase. All design decisions are made with a genuine understanding of how they will be built and how the design aligns with the overall budget.
Milestones
  • Design developed with construction methodology in mind – every decision is grounded in buildability.
  • Updated build cost estimates provided at each stage of design development – giving you ultimate control over your project investment.
  • Interior selections guided and documented alongside the architecture, ensuring a cohesive result.
  • Budget alignment is continuous – no post-approval price shock.
A Clear Path to Approval
We manage the full approval process, documentation and submission, including all consultant coordination, preserving your time.
Milestones
  • DA or CDC pathway managed end to end
  • All third-party consultant requirements (surveyors, arborists, engineers, stormwater, etc.) coordinated.
  • You enter approval with confidence that both your design vision and construction investment remain secure.
  • Construction drawings prepared after approval, ready for your build quote.
One Team. No Handover. No Compromise.
The team that designed your home remains an integral part of your build. Our construction team brings the design to life, while our architecture and interiors teams stay closely involved throughout, ensuring nothing is lost between the design and the finished home.
Milestones
  • Backed by HBCF insurance and the confidence of a fixed price quote.
  • Weekly reporting and regular onsite walkthroughs keep you informed and involved
  • Design intent is preserved throughout construction – details don’t get value-engineered away
  • Vetted subcontractors and suppliers who meet MILEHAM’s impeccable standards of quality and empathy.
The Moment You Walk Through the Door
This is the moment it was all for. The front door opens, and the home you’ve imagined – the light, the space, the way every room connects – is real. It’s yours. And it feels exactly the way you hoped it would.
Milestones
  • Final walkthrough and detailed quality inspection completed together.
  • Every finish, every detail, every material selection – delivered as designed.
  • A home built on budget, on brief, and with nothing compromised along the way.
  • Not just a house that looks beautiful – a home that works for the life you’ve wanted.

““James articulated the opportunities and drawbacks of our home clearly. The renovation consultation was impressive – he offered creative, practical ideas that aligned perfectly with my vision and budget. It’s clear why they’ve won awards! I highly recommend James and the MILEHAM team for anyone seeking expert advice.””
