Self Storage Unit Mix & Self Storage Layout


Self Storage Unit Mix & Self Storage Layout


Whilst facilities do require aisles for fire escape purposes, the design of the unit layout within a facility should aim to minimise the number of aisles / corridors / hallways to minimise non-rentable space. This can be achieved by incorporating deep units and taking advantage of ends of unit blocks for smaller units etc. However, it is also vital that the proportions of each room are suitable for access and storage and so it is important that we manage the design process for you from day one to ensure an efficient and timely return on your investment.


Consideration of the number and size of each room is one of the most important tasks during the design and construction of your self-storage facility. It is important to ensure that whoever walks through your reception doors has a room that is suitable for their needs and therefore makes your sales process all the more easy.

The greater the number of rooms in your facility, the smaller the average size of room will be; and the smaller the average room size becomes, the higher the price for the manufacture and installation. Therefore, it is important to know what rooms will sell, how many of each you need and how flexible those room sizes can be.

It would be foolish to build a facility that only had very large or very small rooms as it is highly unlikely that you will be able to satisfy your customers needs.

Most facilities are fitted out in phases, which has great advantages when planning the unit mix because you can start with a mix of unit sizes in your first phase that doesn't necessarily suit the demand i.e. you run short of 75 sq ft units but have too many 100 sq ft units. In the second phase, you can then build according to your experience of what you built in the first phase. Often facilities are built in three or more phases, which provides even more scope to refine your unit size supply to customer demand.

The catch to this is that for no scientific reason your ideal unit size mix this year maybe different next year and different again the next as you see demand for certain sizes rise and fall. Of course, units will vary from these commonly used sizes, both out of choice and also because unit blocks do not always work out as perfect sizes, the last unit on the end of a block of 75 sq ft units may be for example a 65 sq ft unit.


By manipulating individual unit prices up or down or offering promotions on certain sizes these fluctuations can be catered for. Whilst not ideal, combining for example a 75 sq ft unit and 25 sq ft unit to make up a 100 sq ft required for a customer when all 100 sq ft units are full can spread the overall occupancy levels of individual unit sizes.

Due to the natural churn or turnover of customers, self storage facilities rarely exceed 90% occupancy and therefore, there is always an element of flexibility that usually ensures no sales are lost through lack of individual unit size availability.
