There are eight Silo Rooms which are 41m² (441ft²) including a balcony with spectacular harbour views. While these rooms are slightly smaller, the bathrooms are as large and majestic as other room categories. Double volume spacing mean the floor to ceiling pillowed glass windows offer 5m high views across the Cape Town Harbour.

There are six Duplex Suites across the 6th and 7th floors with either mountain or harbour views. These suites vary between 76m² (818ft²) and 88m² (947ft²) including a small balcony and each has the bedroom on a mezzanine level. These rooms maintain the same 5.5m high windows, but have half the ceiling height due to the two mezzanine levels.

There are seven Deluxe Superior Suites across the 8th, 9th, and 10th floors with spectacular 5.5m (18ft) high pillowed glass windows showcasing the natural wonder of Cape Town. They range in size from 60m² (646ft²) to 67m² (721ft²) including a balcony.

The 211m² (2012ft²), one-bedroom penthouse is the jewel in The Royal Portfolio's crown located on the top floor of The Silo facing Table Mountain with triple aspect views of Cape Town. This includes a 24m² (258ft²) balcony.
