CUSTOM HOME BUILDER – HAWKESBURY, NEPEAN, LOWER BLUE MOUNTAINS & HILLS DISTRICT
A HOME DESIGNED AROUND YOUR LIFE, NOT AROUND SOMEONE ELSE'S FLOOR PLAN.
A custom built home means every room, every detail, and every decision starts with you – on your block, in the location you’ve chosen and built to last.
WHAT IS A CUSTOM BUILT HOME?
DESIGNED FROM SCRATCH, TAILORED TO YOU.
A custom built home isn’t chosen from a brochure or adapted from a standard floor plan. It’s designed from the ground up around the block it sits on, the family who’ll live in it, and the life they want to live there.
That means your orientation, your layout, your flow, your finishes. A home that works for the way you actually live — now and in the years ahead. Built above minimum standard, with nothing carried over from someone else’s decisions.
We work with homeowners across the Hawkesbury, Hills district, Penrith, and the lower Blue Mountains — including Windsor, Richmond, Castle Hill, and Glenbrook — who are ready to build something genuinely theirs.
SHOULD YOU BUILD A CUSTOM HOME?
HOW TO KNOW A CUSTOM HOME IS RIGHT FOR YOU
YOU'VE FOUND THE RIGHT BLOCK AND YOU WANT TO MAKE THE MOST OF IT
Whether it’s acreage in the Hawkesbury, a hillside in the lower Blue Mountains, or a family lot in the Hills — a custom home makes the most of what your land offers.
YOU WANT A HOME DESIGNED FOR THE NEXT 30 YEARS, NOT JUST THE NEXT 5
Your family will grow, your life will change, and your home should be ready for it. Custom design means you’re thinking ahead, not retrofitting later.
YOU'VE LOOKED AT DISPLAY HOMES AND NOTHING QUITE FITS
Volume builders work from a catalogue for a reason — it suits their process. If you’ve found yourself constantly compromising, a custom build is your answer.
YOU WANT ONE TEAM, ONE POINT OF ACCOUNTABILITY FROM START TO FINISH
No handoffs to project managers you’ve never met. Our team is across every detail, and you’ll always have someone who knows your project inside and out.
HOW WE WORK
A CLEAR PROCESS FROM DAY ONE TO HANDOVER.
Building a custom home is one of the biggest investments you’ll make. Our pre-construction process exists to protect that investment — making sure the home you design is the home you can build, with no surprises along the way.
PRE-CONSTRUCTION
We cover your block, brief, and budget. Preliminary drawings, architect shortlist, and a proper budget qualification so everything is aligned before you commit.
DESIGN & DOCUMENTATION
This stage includes full design development, thorough documentation and detailed budgeting – all completed before construction begins. Selections pre-chosen to avoid unnecessary budget creep.
BUILD & HANDOVER
Our team manages every stage of the build – trades, schedule, quality control. You’ll have a clear point of contact throughout who knows your project inside and out.
If this sounds like the kind of build process you’re after, we would love to hear from you.
SEE OUR WORK
BUILT ABOVE MINIMUM STANDARD. EVERY TIME.
We build above the minimum standard – not just to meet a 7-year warranty period, but to create homes that stand strong for the next 50 years. By going beyond the building code and holding ourselves to a higher standard, we deliver better outcomes for our clients.
WHERE WE BUILD
CUSTOM HOME BUILDERS ACROSS THE HAWKESBURY AND SURROUNDS.
We build custom homes across the Hawkesbury — including Windsor, Richmond, and Kurrajong — as well as the Hills district (Castle Hill, Dural, and surrounds), Penrith, and the lower Blue Mountains including Glenbrook, Springwood, and Blaxland. We know the local councils, the block types, and the planning requirements — and that knowledge directly benefits our clients.

OUR SERVICES
KNOCKDOWN REBUILDS
You don’t have to leave the street you love to get the home you want. At JMAR Building Co, we manage the entire process from demolition right through to handover. You can start completely fresh without leaving the place you call home.
RENOVATIONS & EXTENSIONS
For homeowners in the Hills, Hawkesbury, and surrounds who love where they live but know the house needs more – more space, better flow and rooms that actually work for the life they’re living now.
SECOND STOREY ADDITIONS
More space, without the upheaval of moving, this is perfect for families who love where they live and want to grow into it. A second storey addition gives you the extra space, built properly into the existing structure so the whole house feels like it was always meant to be that way.
