A dated exterior and unusable extension were upgraded into a modern, well-insulated home with a comfortable new gym space.
This renovation focused on upgrading a 1990s single-storey home in Milson, Palmerston North. The homeowners wanted to improve the exterior of their 330 sqm property and create a new 60 sqm gym and recreational space. The existing extension had several issues, including leaks, uneven floors, and outdated joinery, making it uncomfortable to use year-round.
Refresh Renovations was engaged to redesign, plan, and deliver the complete upgrade. The project included new cladding, structural repairs, flooring changes, the removal of extensive joinery, and a full exterior paint finish.

The pricing in the build contract was $106,515.68, and the invoiced amount came to $106,116.11. One significant change occurred during construction: the plan was to polish the existing concrete floor in the new gym area, but once exposed, the concrete was found to be in poor condition. To fix this, the team switched to carpet tiles. This change helped maintain quality while keeping the project close to the agreed cost.
The homeowners were comfortable with the cost because they had been involved in previous projects with Refresh and trusted the process.
The scoping and feasibility process began in April 2024 and continued until October 2024, giving the clients time to refine the plan. Construction started in May 2025 and finished in November 2025. The exterior painting required dry, stable weather, so the team waited for the right conditions to achieve a high-quality finish.
Refresh Renovations managed the complete design and planning phase.
The clients were clear about wanting a usable, comfortable space. Their home is multi-generational, so improving insulation, temperature control, and overall durability were important.
The entire exterior of the 330 sq m home was repaired and repainted. It not only fixed performance issues but also refreshed the home's look and prepared it for long-lasting exterior paint.
The team upgraded the entire extension, including:
The homeowners now have a gym space that feels comfortable in both summer and winter.
The extension featured extensive custom-made window joinery, the largest the team had ever worked on. Removal was challenging due to strong Manawatu winds, but the team handled it safely. New joinery was installed to improve warmth and reduce heat loss.
The plan was to polish the existing concrete floor, but it wasn’t in good enough condition. Solution:
✔ Grind the surface
✔ Install carpet tiles
It provided a clean, durable finish suitable for a gym environment.
The final stage included a complete exterior repaint. Because the weather can affect paint quality, the team waited for stable conditions. The result is a fresh, modern exterior that pairs beautifully with the cedar cladding.
The existing framing did not meet building code requirements and therefore needed to be replaced with thicker, more structurally sound framing.
The extension’s concrete pad was poured higher than expected. The team had to grind it down to allow proper installation of new flooring and joinery.
Removing the extensive joinery was difficult due to strong winds. The team used safe lifting strategies and completed the work without damage.
The homeowners have a large dog, so timing had to be clear each day. The team worked closely with the clients to arrange doggy daycare when trades were on-site.
The team loves the final look, especially the cedar cladding, which adds warmth and texture against the existing plaster exterior. The upgrade has modernised the property while still blending naturally with the original structure.
Inside the gym, the new joinery and insulation make a big difference. The temperature is now much more comfortable, making the space ideal for workouts, hobbies, or entertaining.
The homeowners wanted a safer, more comfortable extension. Their old space was:
Because this is a multi-generational home, they needed a room that could be used year-round. They had already completed several upgrades with Refresh before, so they trusted the team to handle this project as well.
This Milson home now has a stronger exterior, a modern look, and a spacious new gym area that feels great to use year-round. With updated cladding, new joinery, better insulation, and a fresh exterior finish, the entire property feels upgraded and future-ready.
