The constant battle for views can be seen in some recent building forms such as the 8 house design by Bjarke Ingels. This building maximises views to the water but with the use of metamaterials the possibility to create any shape desired through light refraction is getting closer.
The most successful method I have come across to make materials invisible is the mirage effect discovered at University of Texas, Dallas. This works through using heat gradients and heating up nanotubes to create a artificial mirage which could possibly be used to hide entire 3D objects. This video below is a small scale demonstration of the technology in action.
The problem with the mirage effect is it would require large amounts of consistent energy to render a object invisible but Metamaterials can manipulate light purely with their own properties. The mirage effect has been successful already but Metamaterials are not quite to that level quite yet. According to Ortwin Hess, a physicist who recently took up the Leverhulme Chair in Metamaterials at Imperial College London, called recent development "A huge step forward in many ways".
This research is ongoing and it is only a matter of time before the technology to incorporate semi invisible sections into architecture will become available.
