Residential Building Services in Nelson & Tasman

  • As an award-winning residential building company, Forme Build delivers architectural new home builds across Nelson and Tasman with a focus on clarity, build quality and integrity.

    Led by Licensed Building Practitioner Jason Callister, we work closely with homeowners, architects, engineers and designers to bring considered architectural homes to life - even where designs are complex or sites are technically demanding.

    Our approach balances architectural intent with practical buildability, ensuring every new home is carefully constructed, well resolved and built to last.

  • Forme Build delivers architectural renovations and extensions across Nelson and Tasman, working within existing homes to create well-considered, high-quality additions and transformations.

    We manage complex structural changes, additions and reconfigurations while working respectfully within occupied or established homes. With a strong focus on construction sequencing, detailing and integration, we ensure new spaces connect seamlessly with the original structure - creating renovations and extensions that feel intentional, resolved and built properly.

  • Forme Build specialises in building on hillside and technically challenging sites across Nelson and Tasman, where access is limited, ground conditions are complex and careful planning is critical.

    With more than 20 years’ experience delivering residential projects on steep and constrained sites, Jason Callister brings a depth of practical knowledge and a genuine enthusiasm for solving difficult build challenges. From foundation design and site access through to sequencing and construction, we take a thoughtful, methodical approach - turning complex sites into well-resolved homes that are built properly and perform as intended.

  • Forme Build undertakes complex structural repairs and remedial building work across Nelson and Tasman, addressing issues where homes require stabilisation, strengthening or partial reconstruction.

    Our work commonly involves temporary propping with acroprops, installation of ground beams and ground anchors, structural block work, piling solutions, and carefully sequenced reconstruction to restore integrity to the building. Using specialist access equipment such as hiabs and cranes where required, we manage technically demanding repair projects with a methodical, safety-first approach - coordinating closely with engineers to ensure remedial works are properly resolved and built to perform as intended.

  • Forme Build delivers insurance and weather-event repair work across Nelson and Tasman, responding to damage caused by slips, flooding, ground movement and severe weather.

    Our repair projects often involve structural stabilisation, temporary propping with acroprops, installation of ground beams and anchors, piling solutions, and staged reconstruction of affected areas. Where access or site conditions are constrained, we utilise specialist equipment including hiabs and cranes to safely carry out the work.

    Led by Jason Callister, we take a calm, methodical approach to complex repair work - embracing the challenge these projects present and taking real satisfaction in seeing families safely back in their homes once the work is complete.

Our Process

Plan with Purpose

We begin by understanding the brief, site constraints and design intent, developing a realistic and well-considered path forward from the outset. This early clarity helps align expectations and sets the project up for success.

Collaborate Openly

You’re part of the process. We collaborate closely with homeowners, architects, engineers and consultants, ensuring clear communication, shared decisions and a well-coordinated build from start to finish.

Build Thoughtfully

Every project is different. We remain flexible and responsive as work progresses, carefully resolving details on site to ensure the build aligns with both the design intent and real-world conditions.

Deliver with Integrity

When the project is complete, it’s not just finished - it’s properly resolved. We take pride in delivering work that reflects care, quality and attention to detail, and that performs as it should long after handover.

  • "Forme Build have been responsible for a major rebuild of our property after a weather event. Jason is an excellent communicator, involving us fully in the process whether it be requests from us or creative improvements based on his experience. Most impressively he worked within our budget with no cost overruns. He is totally trustworthy, organised and reliable".

    Greg and Ellie Bate

  • "Jason Callister's meticulous planning and liaising with engineer and architect not only produced what we proudly call our Grand Design carport (on our tricky hillside section), but his pre-build costing and estimates were spot on. It was a pleasure having Jason and his apprentice, Tom, come to our home each day.".

    Bronwyne Strawbridge

  • "Jason and his team put in an extensive outdoor project for us with pool, decking, cedar fencing and services. An exceptional person to deal with, thinks outside the box and looks at every scenario practically and with great care. Couldn’t ask for more".

    Veronica Hippolite-A'Court

  • “We love our new home: Building a house while living remotely could have been a big challenge, however Forme Build handled the build wonderfully. Their high quality work, attention to detail and communication made the whole process smooth from start to finish.”
