Multi Plus – Full Installation £39,745
Multi Plus – External £27,595

The Multi + is the larger of our ‘Multi-purpose’ standard buildings, designed to be used for a variety of functions. Its size makes it ideal for multiple purposes, including a home office, gym, leisure or entertainment space, teenager’s den, games room, music studio, and more.

We offer two finishing options for our buildings: Full Installation and External (see below for more information)

The door and window configuration can be adjusted to meet your requirements and garden layout. We also commonly build internal partition walls so the building can be divided into two or more separate rooms.

Case Study: Multi + Garden Office Building in Kent

With a shift to working from home, our client needed a dedicated workspace from home.

Our client also wanted to use the building as a home gym, so we decided that a 7.1m by 4.4m building would be the best size.

This building included an aluminium 3-leaf bi-folding door, which allows even more light through the front of the building.
