Shopping Centre ~ Floor Plate Ideas

Ok. So the whole aim if the floor plates is to provide easy flow through the site, allow for easy thorough fair and allow as much light to enter and glass as possible. The other day I came up with the idea of designing the floor plates around a centralized 'dome' of light which is on the level of the park?

In doing so, it had to be multilevel with different voids and approaches to make it feel rather spacious as well as giving visual contact to the outside world. How can I do this? Instead of making it like a glass box, if I position the floor plates around the outer skirts giving central attraction to the 'atrium' (being the centre point) navigation/light and visual connection through glazing can all be achieved.

3 Levels for the internal shopping centre. Keeps the connection with the park on the roof to a minimum.

In addition to the centre atrium, I also thought about including a river like glass piece across the whole site in the roof which will also give extra natural light but also develop soft touches if it were a penetrated piece.

Lighting effects just through simple penetrations.

Same principle idea as above however just a lot more holes which gives a different play of light. 

From the two examples above with the roofing penetrations, I think that for a shopping centre which is attempting to be a very bright space in itself, the larger penetrations are far more appropriate in conveying this message.
