One Seamed Skin Wrapping Roof and Wall
Remove the eaves as a visual event: the same seamed metal continues from roof plane to wall plane, with the seam lines running through the turn, so the envelope reads as one folded skin rather than a roof set on a wall.

Where this idea works
Where this idea works
Contexts this direction tends to suit — and, honestly, where it may not.
- Compact forms where a single wrapping material would read clearly
- Buildings where the roof and upper wall are one gesture
- Owners drawn to a sculptural, monolithic envelope
- New work where the drainage can be planned to suit the detail
Where it may not fit
Where it may not fit
- Situations where the water leaving the roof cannot be collected without a visible gutter
- Elevations where a continuous metal surface would be out of keeping — confirm with the relevant authority
- Existing buildings where the eaves cannot be reworked without professional assessment
Planning
Planning considerations
- Seam lines dominate how the surface reads, so their spacing and direction are the main composition decision
- The metal has to lengthen and shorten with temperature, and clips let it do so — the turn at the eaves is where that is tested
- Rainwater still has to be collected somewhere, so decide early whether the gutter is concealed, set back or moved to the ground
- The deck and separation layer beneath continue through the turn too — confirm that with a qualified professional
Layout
Layout considerations
- The move works best where the roof and upper wall are read together from the usual approach
- Decide where the metal stops on the wall, because that line becomes the building's strongest horizontal
- Openings cut into a wrapping skin need their own resolved returns and reveals
- Corners and verges are folded rather than trimmed, which is what gives the crisp line
Materials & finishes
Materials and finishes to discuss
Named generically as starting points to discuss with professionals — not specifications, and not priced.
Consider:Standing seam zinc, copper or coated steelContinuous supporting deckSeparation layer beneath the metalConcealed or set-back gutterFolded returns at edges and corners
- Ask how condensation on the underside of a thin metal skin is managed in this build-up
- Discuss how movement is accommodated where the plane turns from roof to wall
- Confirm which metals the gutters, flashings and fixings can be, since contact and run-off matter
Maintenance & durability
Maintenance and durability questions
- Ask how localised damage to one tray would be repaired and who could do that work
- Discuss how debris caught between seams and at the turn is cleared over time
Professional review
What to ask a qualified professional
Bring these questions to a designer, contractor or the relevant qualified professional or authority.
- How would the metal be allowed to move where the plane turns from roof to wall?
- Where would rainwater be collected if there is no gutter at the eaves line?
- How would you manage condensation beneath a continuous metal skin here?
- Which metals would you suggest discussing so contact and run-off do not cause corrosion?
- Are there appearance or material constraints I should confirm with the relevant authority?
