02 Services

What we
build.

One accountable team from first sketch to final snag list, whatever the size of the project.

  1. 01

    New Builds

    From bare stand to handover: bulk earthworks, structure, finishes and services, built to your architect's drawings and to the letter of the specification.

  2. 02

    Renovations

    Structural alterations, re-cladding and full-house refurbishments that respect what is worth keeping and replace everything that is not.

  3. 03

    Commercial Projects

    Offices, retail and light industrial buildings, delivered to programme and built around the tenants and neighbours already on site.

  4. 04

    Interior Renovations

    Kitchens, bathrooms and complete interior rebuilds, with joinery, tiling and finishes carried out by our own trades.

  5. 05

    Extensions

    Extra bedrooms, a second storey or an open-plan living space, tied into the existing house so cleanly you cannot see the join.

  6. 06

    Project Management

    Programme, budget, procurement and contractor coordination for owners and developers who already have a design team.

03 How we work

Four steps.
No surprises.

The same clear sequence on every job, so you always know what is happening and what comes next.

  1. Week 1–2

    Consult

    We visit the site, listen to the brief and talk honestly about budget, constraints and timing before anything is drawn or priced.

    • Site visit
    • Budget conversation
  2. Week 2–8

    Plan

    A detailed programme, a fixed-scope quotation and a full procurement schedule, agreed with you and your design team.

    • Itemised quotation
    • Programme and approvals
  3. Month 2 onward

    Build

    A dedicated site manager, our own trades and a weekly written progress report with photographs. Nothing is left to chance.

    • Weekly reports
    • Quality inspections
  4. Handover

    Deliver

    A joint snag walk, full compliance documentation and a 10-year structural warranty. We stay reachable long after we leave.

    • Snag list and sign-off
    • Warranty and care guide

04 About us

We build for
the long term.

NORTHLINE began in 2009 with a simple rule: build every project as if we would be the ones living or working in it.

Founded by a civil engineer and a master builder, we have grown from a two-man renovation crew into a team of 60, but we still quote every job ourselves and still walk every site each week. We believe good construction is quiet: no drama, no excuses, and a building that simply works.

Most of our work comes from repeat clients and referrals, which is the best measure of a builder we know.

  1. i.

    Integrity

    Fixed-scope pricing, honest advice and no hidden extras.

  2. ii.

    Craftsmanship

    Our own trades, our own standards and a habit of getting the details right.

  3. iii.

    Safety

    Every site is run to the OHS Act, with daily toolbox talks and zero tolerance for shortcuts.

  4. iv.

    Accountability

    One point of contact, from the first meeting to the last snag.

05 Why NORTHLINE

The way we
work.

Any builder can promise. We put it in writing, and then we do it.

  1. Transparent communication

    A weekly written report with photographs, a shared programme and one project manager who answers his own phone.

  2. Quality workmanship

    Our own crews, inspected against a written standard at every stage, not only at the end.

  3. Detailed planning

    Itemised, fixed-scope quotations and full procurement schedules before we break ground.

  4. Professional project management

    Programme, budget, subcontractors and compliance, managed by people who have done it hundreds of times.

  5. Reliable timelines

    Realistic dates, protected by allowances for weather and lead times, and a clear record of meeting them.

06 Clients

In their
words.

They finished two weeks early and the final snag list had fewer than twenty items. I did not know a builder could do that.
Marc & Yolande T.The Ridge House, Johannesburg
We lived next door for eight months and every Friday we got a written update with photos. Never once did we have to chase.
Ayesha R.The Olive Renovation, Benoni
Built in a live business park without a single tenant complaint. That is planning, not luck.
