WOW! You've done a great job with your cabin sir Justine! The place is awesome. A beautiful landscaping with abundant green plants will surely give a homely vibes.
The flowing water can be developed into natural inland resort too. A bridge that connects from the cottage to waters would be great. I suggest that you save some amount to secure a solar panel for your lightings. That will save a lot of energy for everyday use. How's that. A vacant space for tents while star watching and grilling your favourite BBQ's would be awesome too. You're almost there and good luck!
Thank you. Eventually we hope to have more stairs leading to the river, now there is only one easy way to get there. We have a lot of battery backup lights, but nothing solar because the solar panels and batteries take many years to pay for themselves. Our electric bill here is usually only $10 USD or so because we don't use aircon or fans.
