You need the foundations first, a good block on the high side of the street with a pleasent view of the surrounding rolling hills and the city. Sounds good this is a gently sloping block of over 1,100 M2 that lends itself to a tri-level or two storey home with the garages under. There are many great building plans that would suit this block, pick up a copy of the subdivision from the office they are really selling fast, the price has risen about 20% in this subdivision in the last 12 months.
