Replacing the Skirting With a Lit Shadow Gap

A wall-base construction decision that deletes the skirting altogether and puts a concealed source in the recess left behind, giving a room-wide low layer with no fitting anywhere — and taking on the jobs the skirting used to do.

Where this idea works

Where this idea works

Contexts this direction tends to suit — and, honestly, where it may not.

  • Walls being built or lined, where the recess can be formed at their base
  • Rooms wanting one continuous low layer rather than individual fittings
  • Schemes where a skirting would be the only applied trim left in the room
  • Floors flat enough to take light running along them

Where it may not fit

Where it may not fit

  • Rooms where the skirting is covering the floor's perimeter expansion gap and nothing else would
  • Uneven floors, where a gap of varying height reads as an error
  • Existing walls where forming the recess means rebuilding the base

Planning

Planning considerations

  • A skirting covers the floor's perimeter expansion gap and protects the wall base, so removing it leaves two jobs that need another answer from the flooring installer and a qualified professional
  • The gap is formed as the wall is built or lined, which makes it first-fix work rather than decoration
  • Light running along a floor shows exactly how flat that floor is, which the room may not flatter
  • Decide whether the gap is lit on every wall or only some, since a partly lit gap reads unevenly

Layout

Layout considerations

  • Hold the gap at one height all the way round, because the floor line is the line the eye checks
  • Decide how the gap turns a corner and how it stops at a door lining
  • Keep the source back within the recess so it is not seen from a seated position
  • Consider what the wash lands on, since a matte floor and a polished one behave very differently

Materials & finishes

Materials and finishes to discuss

Named generically as starting points to discuss with professionals — not specifications, and not priced.

Consider:Recessed skirting profiles and channelsLinear strip with a continuous diffuserFloor finishes with a perimeter expansion gapPlasterboard linings and beadsRemote dimmable drivers
  • A wall base with no skirting takes knocks from feet, furniture and cleaning equipment
  • Diffusers at floor level are kicked and mopped against
  • Movement between wall and floor shows at the gap, where a skirting would have hidden it

Maintenance & durability

Maintenance and durability questions

  • The recess collects dust and is awkward to reach along its length
  • A failed section inside a plastered recess may mean opening the detail, so access should be planned

Professional review

What to ask a qualified professional

Bring these questions to a designer, contractor or the relevant qualified professional or authority.

  • What covers the floor's expansion gap once the skirting is removed, and does the flooring installer accept that?
  • Can the recess be formed while the wall is being built or lined?
  • How flat is this floor, and how would a grazing light read across it?
  • How is the gap stopped at door linings and turned at corners?
  • How would a failed section be reached once the wall is finished?
