We have a separate package for detailed interior design of internals such as kitchens, cabinets, windows and doors and other details as necessary. The cost of this is dependent on the extent of the works. You may also want electrical and lighting design as well as plumbing and drainage. These include normal plumbing and drainage, CCTV, internet, intercom systems, centralized cable TV, specialized lighting etc. You may need to bring on board one of our Engineers (paid separately) to prepare that for you.
