Services
Competitive tenders are won before the first sod is turned. We translate your construction methodology into intelligent 3D models and 4D animations, sequencing, traffic phasing, temporary works, and stakeholder comms all in one visual story.
Used by Isaac Construction and Fulton Hogan for high end tender submissions, ECI engagements, and community consultation where clarity makes the difference in winning stakeholder confidence.
Service Overview:
Surface potential risks and constraints before they become problems
Clearly demonstrate the relationships between construction disciplines, public access and how they interact during construction
Communicate safety methodologies and public impact in a way that stakeholders can follow, before works start
Modular Unit & Off-Site Construction
New government rules in 2026 are opening the door to secondary dwellings on most NZ residential properties. We're already building for it.
From our Plimmerton workshop, we design and construct modular units to NZS 3604 off-site, under cover, built to a high standard leveraging our design arm.
We handle everything from layout design and consent through to transport logistics and installation. If you're looking to add a sleepout, home office, or secondary dwelling — now is the time to move.
Service Overview:
Layout Design & Compliance
Off-Site Construction
Transport Logistics & TMP Administration
On Site Installation
Home Renovations, Extensions & Alterations
Most builders hand you over to an architect, then wait. We don't work that way.
As both designer and builder under one roof, we take your renovation from concept through consent to code compliance, with no handoff friction and no one passing the buck.
Structural alterations, high-spec interior upgrades, extensions, fireplace installs… we do it all, and we do it buildable from day one.
Service Overview:
Architectural / high-spec interior and exterior upgrades
Residential fireplace and wood burner installation
Structural alterations and home extensions

Testimonials
“This was a challenging project and you listened into the methodology workshop and created some magic that really tells a story for our tender”
- Julie G, Isaac Construction, Christchurch“The flythrough was definitely a hit, and a key differentiator to the success of our tender. All feedback from my end has been positive”
- Michael C, Isaac Construction, Christchurch5 stars on BuildersCrack
“So happy with our new front entry area. Jay was very organized and purchased the materials ahead of time, arrived on time and got stuck in. He had to get some extra material because we didn't order enough, unforeseen and easily fixed. Jay went back to his supplier and got more, so the job could be finished on time, very happy!!!”
— Jessica A, Christchurch, Landscaping & Home Repair“Jay remodeled three bedrooms in our home, insulating and relining them with a mix of gib and plywood. He also custom built plywood drawers and a wardrobe in our main room and lined our ceiling with ply. The build quality and finish of Jay's work is very high and he is a pleasure to work with. We will definitely be using him again in the future”
— Matt H, Titahi Bay, Porirua, Major Home Renovation“I spoke to a range of builders about remodeling my beach hut. I had a clear idea of what I wanted. I was impressed that Jay listened carefully, clarified points and created exactly what I wanted but made it look better and built it stronger than I imagined. We liked him and his work so much we were inspired to remodel our bedroom too”
