Home Renovations Auckland — Full-Service Licensed Builders

The cost of a home renovation depends entirely on the scope of work. Kitchen renovations in Auckland range from $15,000 for a basic refresh to over $90,000 for a full custom build, with most mid-range projects sitting between $30,000 and $50,000. Bathroom renovations range from $7,000 for a cosmetic update to $60,000 or more for a luxury remodel, with mid-range projects between $25,000 and $35,000. A combined kitchen and bathroom renovation is one of the most common home renovation projects and can be managed together for greater efficiency. TJ’s provides a fully itemised, fixed-price proposal after an in-home design consultation, so you know exactly where every dollar goes before work begins. For room-specific breakdowns, see our kitchen renovation cost and bathroom renovation cost guides.

Start by getting clear on your goals. Are you renovating to improve your lifestyle, enhance indoor-outdoor flow, accommodate a growing family, or adapt to changing needs? Once you know the “why,” set a realistic budget with a 10 to 15% contingency for unexpected issues like hidden water damage or outdated wiring, which are common in older Auckland homes. Then engage a qualified renovation company early. At TJ’s, planning starts with an in-home design consultation where we assess your space, discuss your vision and budget, and provide a rough cost estimate before you commit. From there, we handle detailed site assessments, supplier pricing, and floor plan design. Using project management software with daily logs, we keep you fully informed at every stage. For more detail on what to watch out for, see our guide on the 5 common mistakes to avoid when renovating your home.

It depends on the scope. A mid-range kitchen renovation in Auckland typically takes 5 to 7 weeks, while a bathroom renovation usually takes 3 to 5 weeks. A combined project or a broader home renovation involving multiple rooms, structural changes, or council consents will naturally take longer. Delays most commonly happen when materials are on backorder, when unexpected issues are uncovered during demolition, or when consent approvals take time. TJ’s 5-step renovation process is structured to keep things on track, with detailed timelines, daily progress logs, and a single point of contact coordinating all trades from start to finish. We also include a follow-up three months after completion to make sure everything is still working perfectly.

Kitchen and bathroom renovations are consistently among the highest-return home improvements you can make. Kitchen renovations in Auckland deliver a return of 70 to 120% depending on execution and suburb. A modern, well-maintained bathroom also adds significant appeal and value, particularly when it addresses outdated fixtures, poor lighting, or water damage. The return depends on the quality of workmanship and how well the renovation matches the home’s overall value and neighbourhood. TJ’s backs every project with a 10-year workmanship guarantee and Licensed Building Practitioner credentials.

It depends on the type of work. Cosmetic updates like painting, replacing fixtures, or installing new flooring generally do not require building consent. However, structural changes such as removing or adding walls, significantly relocating plumbing or electrical services, or altering the building envelope will typically require consent from Auckland Council. Heritage-listed properties in suburbs like Ponsonby, Devonport, or Mt Eden may also have additional consent requirements. Skipping this step can result in fines, issues when selling your home, or even having to undo completed work. As Licensed Building Practitioners, TJ’s team knows the regulations inside out and manages all council requirements as part of our full-service process.
