KND Group is holding dinner parties for its buyers into the Lumi Collection building so they get to know each other well before moving in, which will be some time in late 2020.

The 142-unit development is under construction in Swain Street. There are two towers, one 13-storeys, the other six storeys.

Developer George Katheklakis said the Lumi development was amongst a range of other new apartment developments in the area, creating a community within a community.

"It's a fast-emerging little suburb within the town centre itself," he said.

Mr Katheklakis said 85 per cent of sales so far had been to owner-occupiers, which was the target market for the development.

So as a nod to fostering neighbourly ties, the developers were holding get-to-know-you dinner parties for the new residents of Lumi.

"As whole floors start to sell out, we have what we call a level party, bringing them all together," he said.

That has so far been in the Mitchell showroom of Harvey Norman, where a chef prepared a meal, and explained the appliances that were going into their new homes.

"People start to meet and make connections and create those initial friendships," Mr Katheklakis said.

"It's a way of breaking the ice for everyone and it's done well and truly before they move in and it starts to form that community in Lumi."

Mr Katheklakis said there was more to a building's sustainability than only energy ratings.

"If you don't have social sustainability, you're only telling half of the story," he said.

"We appreciate that, we know that. This is our effort to say, 'You guys need to get together. Your neighbours are really important people. They're the ones you're going to go to in times of emergency and they're the people if you form good friendships, can help make your life a whole lot happier'."

Mr Katheklakis said the Lumi development also had wider corridors with natural light, to encourage residents to stop and chat, rather than to scurry into their apartments.

"The six-storey tower has a ground-floor cafe which faces out to a pocket park which we're preserving and which contains this big old tree which were pretty much preserving and celebrating," he said.

The development also did away with podium parking, to remove any feeling of an obstacle as people walked through the building.

"There's a lot of elements in the development which all add up to trying to be a friendlier place for people," he said.
