Composing an Elevation With No Windows in It
Most facade composition depends on openings. This is what to do when there are none: give the blank wall its own order through coursing, a shallow relief, a change of plane or one considered event, so it reads as a designed face rather than as the side nobody looked at.
Where this idea works
Where this idea works
Contexts this direction tends to suit — and, honestly, where it may not.
- Party walls, flank walls and boundary elevations that cannot take openings
- Blank gable walls left exposed by a demolition or by a lower neighbouring building
- Elevations highly visible from a street or footpath but serving rooms that need no light
- Walls where a relief or coursing pattern can be built in rather than applied
Where it may not fit
Where it may not fit
- Elevations where openings could reasonably be added and the blankness is not actually required
- Shared or party walls where the surface may not be yours to alter — a legal question to confirm
- Exposed walls where added relief would create ledges in a driving-rain position
Planning
Planning considerations
- A blank wall is read at a distance, so the pattern has to be coarse enough to register from where people actually see it
- Whether the surface may be altered at all depends on ownership and on the relevant authority, both worth confirming first
- Relief built into the material weathers with it; relief applied to the surface has a separate life and a separate failure
- Movement joints have to go somewhere on a large unbroken wall, so it is better to make them part of the pattern than to discover them
Layout
Layout considerations
- One event on a large blank wall usually reads better than several competing ones
- The pattern can be set out from the wall's own edges, since there are no openings to align to
- A change of plane gives the wall a shadow that moves through the day and asks nothing of a finish
- Consider how the blank face meets the elevations either side of it, since the corner is where it is judged
Materials & finishes
Materials and finishes to discuss
Named generically as starting points to discuss with professionals — not specifications, and not priced.
- Large unbroken walls move, and where that movement is accommodated is a matter for a qualified professional
- Projecting relief creates ledges that hold water and dirt in a way a flat wall does not
- A wall with no openings has no natural interruptions to run-off, so water sheets down it in long unbroken paths
Maintenance & durability
Maintenance and durability questions
- Long uninterrupted surfaces show streaking clearly, so periodic cleaning is more likely to be wanted
- Access to a boundary-facing wall may depend on a neighbour, which is worth settling before the surface is chosen
- Relief and recesses collect debris and organic growth on shaded aspects
Professional review
What to ask a qualified professional
Bring these questions to a designer, contractor or the relevant qualified professional or authority.
- Who owns this wall surface, and what may be altered on it?
- Where would movement joints fall on a wall this size, and can they be made part of the pattern?
- Which relief or coursing approach would a qualified professional consider buildable in this material?
- How would you expect a wall with no openings to weather and streak on this aspect?
- What access would be available to this face for construction and for later cleaning?
