3D house design and floor plan

We’re not having much luck selling our house:

I need some quick drawings showing the property’s full potential. Needs to look fancy, but we can guestimate measurements based off existing floorplan. Going for full on wow factor rather than what will get past planners.

The idea would be to build above the front of the playroom/garage and bring the first floor forward so it sits on the pillars to create new master bedroom. Convert the loft into two bedrooms and a bathroom. Small single storey extension with roof lantern behind the playroom. Knock through existing utility room and create new utility room in the back of the garage. Stick wide bi-folds on the back. And have one (or two) apex in the roof line at the front with glass going all the way to the top (so lots of glass basically).

We need a proposed floor plan and 3D front and rear elevations.
