Custom Bed

I have some ideas on how the kids bed would be. Now they're using pull out beds but I was thinking maybe have seperate beds and a pullout if they have their cousin sleeping over. And I chanced upon this design which I think would be perfect. Both the kids will have their own bed space and they can lie on them anytime they want. They could also get out of bed with ample space without having to step on the other bed or their sister! I have sent out an email enquiry on 3 different carpenters in Singapore. Hope to hear from them.
