Renovations – adding a 2nd bathroom to a 1 bathroom unit

I am on the EC for our block and the EC is concerned about a renovation occurring in our building.

The Owner asked for conditional approval to re-tile bathroom, redo kitchen, re-carpet, paint and new blinds. All seems straight forward so approval was given.

Then walls started to be removed – at this stage we insisted on an engineers report. This report highlighted that beside walls being removed doorways were added and the main bathroom was divided in half creating 2 rooms. A new room is also created off the 2nd bedroom from the old laundry and pantry.

We are concerned. What are these rooms used for? If bathrooms are they waterproofed, correctly ventilated, plumbing/sewerage etc.

We have asked for detailed renovation specifications and Council Approval as his unit is only meant to have 1 bathroom according to our DA approval. No Conditional Approval has been given for these extras renovations. Are we within our rights to ask for these details as he has threatened Fair Trading.

Thanks Slim
