Your client, Dwayne Johnson, has been living in his house at 4 Leary Avenue for two years. The house was built according to the plans provided with no major changes being made.

Mr Johnson has decided that he would like to add a single-storey extension to house an elderly relative. The extension will be small in size due to the limited available space on the block, but as a minimum must include a single bedroom combined with a living area and small bathroom for mobility access. The extension must also be fitted with handrails and wide doorframes, as the relative is frail and uses a walking frame and a wheelchair.

Mr Johnson has decided to situate the extension at the back of the garage. The initial plan involves the following:

• 5.6m x 4m slab (extended from back of garage)
• Rear door of garage to be bricked/blocked/insulated
• Window 8 of Family Room removed
• Wide/Double doors inserted in place of W8
• Sliding door at rear of new room into yard
• Provide as a minimum a 1.2m wide landing from the rear of the extension to then connect a 2-meter ramp from the landing at the rear of the extension into garden
  • Make sure you do not obstruct W7 of the dwelling
• Mobility-access bathroom
• Double power outlet x 3
• Downlight x 1
• Smoke alarm if required refer to the NCC Volume 2 section Smoke alarms
