Kitchen & Dining

Kitchen & Dining rooms are a central part of the home, they bring the family together during the best time of the day – meal time!

Master & Kids Bed Rooms

A bedroom renovation will not only add value to your home – increasing sale potential, it will bring you satisfaction for years on end.

Living Room

Living rooms are a place for gathering, conversations and entertaining. Renovating a small and closed off living room into a modern, welcoming space will always score big.


The Bathroom is a high traffic area and a hidden show piece in the home. As a space, we consider this zone a high value renovation area. You can add a lot of value with subtle or significant changes.


The Laundry is a highly functional utilitarian space in the home. We do our washing, drying & folding there – it’s practical. A Laundry renovation can convert this space to match the theme and design of your home seamlessly.
