Mrs Bantam here (Jenny) We have bought in Block 3 Phase 4 and are currently in a long term rental in Phase 3. Our balcony overlooks Phase 4 Blocks 9,10 and 11. The blocks which have the most still to be done appear to us to be 7,8&9.
Our Block 3 along with 1&2 has been finished since last November and currently they are being cleaned ready for occupation.
Block 11, has windows and doors in and there is a paint wash over most of its rendering however can't see how far it's complete internally as there is a security fence round it. It also looks as if there is still work to be done in terms of access to the car park.
Yesterday a team of builders started work on Block 9, clearing away rubbish from inside the block and levelling the ground in front.
My guess is that you could be looking at another 6 months or so but it all depends on how many builders they bring in and how long it takes to get the occupation licence from the local Council.
Are you aware of the Arenal Golf Portal?
Hope this helps
