Thanks for the comments guys!
All the images were commissioned images for the project except the final kitchen crop - that's just a crop of the main kitchen image with some DOF as an extra for the development's instagram page.
We can't take the credit for interior design, this was from the interior designers, but I'd say 95% of the modelling was custom created for the project so was very time consuming. I think in all this stage of the project was around 6-7 weeks.
The lighting was a mix of HDRi and corona sun/sky with drone photography for reflections and backplates. The 4th image just had the sun turned right down to only cast the light on the floor as a last minute request.
No this doesn't exist, yet. But it will be open in 2020. High-end residential always has amenities with lounge and living spaces for owners to use, it's a huge selling point these days. Everyone skips leg day, so why not force it with 3 leg extension machines ;)
