Project address: ______________________________
Proposed work: ________________________________
Intended use / occupation: ____________________

For a Cross Gates, Colton or Whitkirk home, compare using an existing garage with adding floor area at the rear. Both can create another room, but they raise different questions about daylight, levels, storage and access. The useful comparison includes what the household loses as well as what it gains.

DECISIONS TO RESOLVE

1. Check the garage as a room
Measure the existing height and floor level and record where daylight and ventilation could come from. Consider where the contents of the garage will go and whether access through it is still needed.
[ ] Gather: Garage dimensions, floor levels and a storage plan.
Notes: ________________________________________

2. Check what an extension leaves behind
Show the remaining garden, side passage and light to the existing rooms. For a newer property, include the original planning conditions in the documents reviewed before settling the design.
[ ] Gather: A site plan and the original planning decision if available.
