The Brief

A home full of memories, with nowhere to host the grandkids.

Suresh had raised his entire family in his Mt Roskill home. The kids grew up there, then moved out, then came back with kids of their own. Suddenly the home that had always worked was missing one thing: a real space upstairs for everyone to be together.

The brief was a second-storey outdoor entertainment area — somewhere the family could gather, the grandkids could play, and the BBQ could finally have its own room.

We had two jobs: design something that matched the home it was sitting on, and make a Louvretec roof actually work for an Auckland family — sun when they want it, shade when they don’t.

The Outcome

Twice the floor area, and a place to host every weekend.

The new second-storey deck doubled the usable area of the home. Louvretec roof overhead, adjustable on a remote — full sun for lunch, full cover when the southerly hits, easy on a Saturday afternoon BBQ.

Underneath, a covered carport solved the parking problem for a family with multiple cars visiting most weekends. Black bifold doors connect the upstairs to the indoors. The home Suresh raised his family in now hosts the next generation.

The Transformation

Before & After

Before Mt Roskill home before second-storey extension and Louvretec roof

Limited outdoor space, no upstairs entertainment area, and parking that maxed out fast.

After Mt Roskill home after second-storey extension with Louvretec roof and BBQ area

Second-storey deck, Louvretec roof, dedicated BBQ space — and a carport solving the parking.

The scope, in plain English.

A second-storey extension with Louvretec roof and a carport underneath — designed for a multi-generation family that loves hosting.

Second-Storey Extension

Engineered second-storey deck addition designed to integrate visually with the existing home — matched roof line, consistent detailing, and structural design coordinated with the engineer.

03

Black Bifold Doors

Full-width black aluminium bifold doors connecting the upstairs living area to the new deck — opens the whole house onto the entertainment space.

Glass Balustrade

Frameless glass balustrade around the deck — clean lines, full view, no visual interruption.

05

Carport + Parking

Carport built under the new deck — solving the multi-car family parking problem and adding a sheltered drop-off zone.

Simon and Joanna of Add Value Renovations planned and completed our en-suite upgrade. We are entirely happy with the finished product and the service and care they provided. We especially appreciated the direct communication with Simon. He is a good man — honest, reliable, and easy to work with. The attention to detail and quality of the finish was outstanding.

We loved working with Simon and the team at Add Value Renovations. Add Value's project manager Tim, and interior designer Joanna, had excellent communication throughout the entire process. The quality of the workmanship was top-notch and they completed our bungalow renovation on time and on budget.

Just wanted to take a moment to express my appreciation for the outstanding work you've done! A ext. renovation done by Add Value was truly a remarkable transformation. The kitchen and bathroom designs are not only aesthetically stunning but also highly functional. It's evident that a lot of thought and care went into every detail.

We have used the services of Add Value Renovations twice over three years, once for bathroom renovations and more recently for our kitchen and deck. The quality of work has always been excellent and any issues that arose were dealt with promptly and professionally.
