College art block Redesigning ideas

For my next idea of redesigning an area in colchester, i have decided to try and redesign the college art block. The college art block was not originally designed for  art students  as it lacks a large working space and does not have any attractive visual points. My idea is to redesign the art block into something more suited for art students by having larger working space and a viewing gallery. I feel the building also needs a new modern look as it looks very dated and dull.

Here is a quick sketch of the  art block from the front of the car park. The design of the existing building is very flat and has no modern shape. it also uses old metals such as brick and wood and does not feature and modern materials such as steel and glass.
Due to the old buildings materials. a big problem is heat lose and draft problems. During the winter and colder sessions, the room rapidly gets very cold and makes it difficult for students to work. 

The interior design is very cramped and limited as the building is divided into  several working rooms. this limits the working space of each student.

Above is the original new design which the college proposed to design for its students. however due to funding the college is unable to build this design. My alternative solution is to design something smaller and within its fund budget. 

For my first idea, i have designed the building in a long and sleek shape. The roof is the buildings most attractive part as it features an unusual and appealing design.  The waved roof design creates a  flowing and energetic appeal. The top windows / sun tunnels feature a natural source of light which is great for art student as it allows more light in a organic way, this helps to cut costs of electricity as well.
The large slant windows also allow much more light and more visual from inside the building. It also helps the appearance of the building as most modern buildings have large glass panels.

The interior of the buildings is much more efficient as the corridors are of the edge of the building instead of cutting right down the middle. each working section in the middle is dived by glass which makes the rooms seem visual bigger.     

This design is very much different from the last design as this is features alot of lighting by LED's. The roof of the design is an occurring triangle shape which makes the building look bigger and taller.
The windows of this design are a pattern of  4 oval which has built in LED's around them making them look very modern and high-tech. At night this structure will be very noticeable and appealing.
The interior plan is set very different and unusually. The corridor is set and an angle which cuts across the rooms diagonally.  I see this design as a major problem as the room space is different and unfair,
This could cause major issues.
