Metro Vancouver condo builder accountability

[joeyiltlibw]

I bought a junior 2 bedroom condo in Starling Lumina Brentwood in 2017. Suppose to be 642 sq ft . To my horror in a recent walk thru , I discover an area of 3ft x 6.5 ft removed from the second bedroom. The 3 ft x 6.5 ft is now used to house gas meter outside of unit. The second smaller bedroom now becomes an odd shaped den , can no longer function as bedroom . The developer lawyer said this is within the contract variant allowance of 8 %. The location of the gas meter is never meant to be outside of my unit Plan A5 . If gas meter location originally meant to be outside of my unit ; it should have been indicated in the master floor plate when I purchased. But this is not shown in the master floor plate.
. My unit now only 622 sf, a very noticeable alteration of floor plan . Wonder what your thoughts are if you purchase a condo of 642 sf and now become 622 sf ..... even smaller than their 1 bedroom and den design (Plan A 9 )which is 632 sf?
Had I known this to happen , I would have bought the 1 bedroom and den unit ( plan A 9 ) much cheaper by $30000.
Do you think builder should be allowed to be protected by the construction variance clause?
