Offices above the warehouse
Keep the ground floor for goods and give staff a place to work upstairs. We can install the steel floor and stairs, then fit out the offices with partitions, power, lighting and data. Tell us how many people will use the rooms and where they need access.
Storage and working space
What will you store upstairs, and how will it get there? Shelving for boxes picked by hand needs a different layout from a floor that takes pallets. We look at how goods reach the deck and which aisles, packing benches or loading doors must stay clear below.
How two businesses used their new floor
Four offices in a glasshouse near Chichester
Hill Brothers needed more office space at its growing site near Chichester. We built a mezzanine inside a glasshouse with four offices and an open area upstairs. A staircase and bridge connected the new floor to the reception, kitchen and staff facilities below.
A storage floor during Proporta’s shutdown
Proporta had one weekend to install a storage floor. Its racking and despatch equipment had to stay in place. We installed the floor over the three-day shutdown. The fire protection, lighting and emergency lighting followed over the next few days.

What affects the price and installation programme?
The size of the floor is a starting point. What it needs to carry, how staff and goods reach it, and what you want fitted above or below all affect the price. A storage deck and a finished office of the same size can need very different work.
What do you check on a site visit?
We check the available height, the existing floor and the space for columns and stairs. Show us any areas you need to keep clear. If you have a sketch or dimensions, they can help us discuss the options before a visit.
Can we keep working during installation?
Tell us about busy shifts, despatch times and planned shutdowns. At Proporta, we agreed which work had to fit into the weekend and which could follow. We can discuss the order of work for your building before agreeing a programme.
