One Deliberate New Opening Instead of Several Domestic Ones
Where the existing openings genuinely cannot serve the new use, making one deliberate and unmistakably modern opening on a lesser elevation, so the building reads as itself plus a single clear addition rather than as a facade quietly domesticated.

Where this idea works
Where this idea works
Contexts this direction tends to suit — and, honestly, where it may not.
- Buildings with a strong principal elevation and a plainer secondary one
- Shells where a run of small new windows would dilute the composition
- Owners comfortable with new work that declares itself as new
- Plans where the rooms needing light can be arranged on one side
Where it may not fit
Where it may not fit
- Buildings with no secondary elevation available to take the change
- Plans where the rooms needing daylight all sit on the principal side
- Cases where any new opening may not be permitted, which is for the relevant authority to say
Planning
Planning considerations
- Concentrating the change is the argument: one opening that is obviously new usually reads better than several pretending to have always been there
- An opening crosses structure, the drainage plane, the insulation and the air line in one operation, and each has to be returned to the frame
- Which face can be reached decides how the work is done, because on a closed building you rarely have both sides available
- What is permitted on each elevation is a matter for the relevant authority, and that answer may decide which elevation is used
Layout
Layout considerations
- Put the new opening where the room that needs it is, not where the elevation looks emptiest
- A single opening can serve two levels where a void or gallery lets the light through
- Leave the principal elevation to carry the building's original composition
- Consider what the opening looks at, since a secondary elevation often faces the least considered part of the site
Materials & finishes
Materials and finishes to discuss
Named generically as starting points to discuss with professionals — not specifications, and not priced.
Consider:A single large frame or screen in a clearly modern materialStructural support over the new opening (sized by a structural engineer)Tray and flashing provision at the new perimeterReveal linings returning the insulation and air lines to the frameA surround deliberately distinct from the surrounding wall
- The perimeter of a new opening is a junction between new and old work, and that is where water finds a way in
- One large frame carries more movement and weather load than several small ones
Maintenance & durability
Maintenance and durability questions
- A single large glazed element needs a cleaning and replacement route thought through in advance
- New surround and old wall may weather at different rates and show the difference over time
Professional review
What to ask a qualified professional
Bring these questions to a designer, contractor or the relevant qualified professional or authority.
- Would the relevant authority permit a new opening here, and on which elevation?
- What structural support does an opening of this size need, and who sizes it?
- Which layers can be reinstated from inside, and which need the outside opened as well?
- How will the perimeter be drained and sealed where new meets old?
- Could the existing openings be reused so that no new one is needed at all?
