Mezzanine Floor Regulations and Building Control

Mezzanine Floor Planning

When planning a mezzanine floor there are a number of building control factors that would need to be taken into account. We can also advise on mezzanine floor planning permission, although this is less relevant than the mezzanine floor regulations requirements (see below). Though building regulations may appear daunting at first, NSI can take the lead with minimum input from you.  For mezzanine floors, there are building regulations covering:

  • The structural design of the floor itself. Mezzanine floor engineering calculations need to be prepared and submitted to Building Control to prove the weights that the floor is designed to support.
  • The load imposed on the concrete slab – again you need mezzanine floor load calculations to satisfy the building regulations.
  • Mezzanine floor safe access and evacuation are also covered by the fire regulations requirements of Building Control. We can advise you of your responsibilities here, design the floor for compliance at minimum cost, and get an interim approval of the design prior to construction.
  • If the mezzanine floor is over a certain size or percentage of your premises, building regulations require it to be fire-rated. If so, we can design this in a manner to minimise cost or, if the requirement is marginal, negotiate on the mezzanine project with Building Control to gain a waiver from this element of the additional cost.
  • Mezzanine floor regulations also reinforce the requirements of compliance with the DDA (Disabled Discrimination Act) and there are various regulations affecting access and egress from the mezzanine floor, we can advise you to steer you easily to building regulations approval.

Mezzanine Floor Planning Permission

Mezzanine floor planning permission in most commercial applications mezzanine floor planning permission is not required, providing there are no issues that alter the external look of the building surrounding the project (e.g. additional external windows to bring light to the new floor).

In retail applications, or other areas affecting an increase in vehicular traffic, mezzanine floor planning permission may apply. Contact us to discuss in more detail.
