House extensions in Auckland

Adding space is only half the job. The part that decides whether an extension feels right is how the new work meets what is already there.

100+

Renovations, from kitchens to full house renovations, since 2017.

Built on precision

Every estimate is carefully calculated by our specialists so you get a realistic, transparent number from day one.

Your designer

We build from your architect's or designer's drawings.

What we take on

Extensions live or die on what the site and the existing house allow. Before we can price anything, we need to understand foundation and floor levels, boundaries, drainage and services runs, access for machinery, what stage the drawings are at, and the consent pathway.

01

Rear and side extensions

Additional living, bedroom or family space on the ground floor.

02

Major alterations

Reconfiguring an existing footprint - removing walls, changing the entry, relocating rooms.

03

Extension plus renovation

New space combined with reworking the rooms it connects to, which is how most of ours run.

04

Decks and outdoor connection

Where the extension changes how the house meets the garden.

Feasibility before quoting

01

Foundation & floor levels

Whether new and existing can meet cleanly.

02

Boundaries & coverage

Height in relation to boundary, and site coverage.

03

Services

Where drainage, wastewater and power run.

04

Access

For machinery, materials and spoil.

05

Drawing stage

What stage the drawings are at, and who is producing them.

06

Engineering

Whether engineering or geotechnical input is required.

Where old meets new

The junction between the existing house and the extension is the part that gets noticed for the next twenty years. It is also where most of the technical risk sits — structure, weathertightness, floor levels, ceiling heights and the way the two roofs resolve.

We work through that detail at the site visit, with the builder who will run the job in the room. If something in the drawings will not work on this house, it is better to find out then.

The enquiry-to-quote process

  1. 1

    Tell us about the project

    Send the details through the form or call us - what you are planning, roughly when, and any budget limit.

  2. 2

    An initial conversation

    Our admin team calls you to talk through goals, scope, budget and timing.

  3. 3

    Initial home walkthrough

    A detailed on-site review to assess your existing space and map out the exact scope of the project.

  4. 4

    Quote prepared and finalised

    We carefully price the work following our site walkthrough, taking the time needed to ensure your estimate is thoroughly calculated.

What drives extension cost and programme

01

Size and structure

Floor area matters less than how much structural work the connection requires.

02

Ground and foundations

Auckland clay, slope and any geotechnical requirement can move the foundation cost substantially.

03

Services

Extending drainage, power and hot water into new space, and whether the existing board copes.

04

Approvals

Consent processing and any resource consent requirement affects the programme more than the price.

05

Access

A tight rear site with no machine access is a different build to one you can drive a digger onto.

06

Finish and matching

Matching existing cladding, joinery and flooring is often harder than specifying something new.
