The Porter Building is a five storey, 100,000ft² new build development in Slough.

Our client, Landid, wanted to offer possible tenants maximum potential to adapt and modify the building to their future needs, whilst pro-actively managing the economics of a speculative office development in Slough.

To achieve this, the Porter Building design delivers future flexibility and multi-occupancy through its conception and design. A flexible grid and an economic structural solution were important. In the earliest design stages, our structural engineers optioneered multiple solutions to work within the desired 9m grid, creating quick sketch options to help the developer compare initial outlay cost, with lettable area, projected income and project programme.

As the project progressed to completion, the client has been able to retain these solutions for use in future tenancy changes. Parts of the building or single floors can be modified and adapted for future changes in use, including internal staircases, splitting of floors or multi-floor letting depending on the tenant. 

The potentially intrusive noise from the nearby train line and vehicles has been eliminated by incorporating mechanical ventilation and robust external façade constructions. This allows for flexibility in providing the internal noise conditions to suit the noise sensitivity of the future internal spaces.

Structural solutions include an increased percentage of loading by floor to 7.5%. This has allowed floor plates to be easily divided into four tenancies each with a hard spot (i.e. place for server room, archive storage, UPS, etc.). This would be an essential requirement for trading floors or tech companies requiring on-site servers.

The building is designed with sustainability and, health and wellbeing in mind and has gone on to achieve a BREEAM rating of ‘Very Good’ and is the first building in the UK to achieve WELL Standard Core and Shell accreditation at Gold level.

One of the most sustainable features of the building is that the structural loading of the building is designed so that it has flexibility for future modifications, allowing for future updates in the technology, i.e. more efficient, more fire resistant or more sustainable cladding. This will mean that the building should have a much longer life.
