Auckland’s Interior Renovation
& Finishes Specialists

Interior renovation costs in Auckland depend on scope and finish level. A single-room refresh (flooring, repaint, lighting upgrade) starts around $15,000–$40,000. A multi-room interior renovation typically lands between $80,000 and $180,000. A whole-home interior renovation with new joinery throughout, full repaint, new flooring, and lighting design ranges from $150,000 to $300,000+. Premium designer interiors with bespoke joinery can sit above $400,000. The fixed price is locked in your Master Builder contract after design is complete.

Interior renovations are faster than structural work because no consent is typically required and no walls move. A single-room interior refresh takes 3 to 6 weeks on site. A multi-room interior renovation runs 8 to 14 weeks. A whole-home interior renovation usually takes 3 to 6 months including design, ordering long-lead joinery and tiles, and the actual build. Add 4 to 8 weeks of design and selection time before site work starts.

It depends on the scope. For a single-room refresh, yes — easily. For a multi-room interior renovation, most clients stay in the home but accept some disruption (dust, noise, sections of the house offline at different times). For a whole-home interior renovation that includes kitchen and bathroom rebuilds at the same time, we usually recommend moving out for 6 to 10 weeks of the core work to avoid the most disruptive period.

Most interior renovations don’t need building consent because they don’t change the structure or services. Repainting, new flooring, new joinery, lighting upgrades, and replacing internal doors are exempt under Schedule 1 of the Building Act. Consent is required if your renovation includes: removing or altering load-bearing walls, changing the plumbing or drainage layout, replacing the switchboard, or adding new wet areas. We handle any consent work directly with Auckland Council on your behalf.

Yes, a well-designed interior renovation typically returns 100 to 150% of its cost in added market value at sale, especially in Auckland markets where buyers expect a modern, move-in-ready home. Kitchens, bathrooms, and flooring give the strongest return. The trap to avoid is over-personalising — sticking with classic, broadly-appealing materials and colours protects resale value while still giving you a home that feels fresh and modern for ten years.

Yes — we are a design-and-build company. Our interior designer works with you on the material palette, joinery design, lighting plan, and overall scheme before any pricing or building work. You get a fully resolved interior design as part of one contract, not separate design and build phases with separate firms. If you already have an interior designer or architect involved, we work alongside them and price-build to their design.

A cosmetic refresh is paint, lighting, and minor fittings — typically 1 to 4 weeks, no joinery, no plumbing changes. An interior renovation is the next tier — new flooring throughout, new joinery, full lighting redesign, doors and trims, and complete redecoration. Most Auckland clients land on the interior renovation tier because the cosmetic refresh leaves too much of the dated 1990s/2000s detail in place to feel like a real change.

Doing the whole interior in one project is almost always cheaper per room — you pay one set of design fees, one project setup, one bulk material order, and the trades are on site once. Doing it room-by-room over years means living with the disruption multiple times, plus the inconsistency of finishes selected at different times. We usually recommend whole-home interior renovation when scope and budget allow, with a clear phasing plan if you can’t do everything at once.

That’s exactly what good interior design solves. Our interior designer works on a cohesive scheme that ties new interior work back to the architecture of the existing home — picking up details from period features in a villa, simplifying for modern Lockwoods, or going contemporary if the home suits it. Auckland villas, bungalows, plaster homes, and modern builds all need different interior design approaches, and we tailor accordingly.

Yes, every interior renovation project we deliver over $30,000 is covered by the Registered Master Builders 10-Year Guarantee. This is a third-party guarantee underwritten by the Master Builders Association, independent of Add Value Renovations. It covers two years of workmanship and materials, ten years of structural integrity, and ten years of weathertightness — applicable to any structural or weatherproofing work included in your interior renovation scope.
