| Anti-Pattern | Failure Mode | Fix |
|---|---|---|
| Deep plan without daylight | Plan depth > 15 m from facade with no atrium or courtyard. Interior zones permanently artificially lit. Energy waste, poor wellbeing (WELL L01 failure). | Max 12-15 m occupied depth. Introduce lightwells, atria, or courtyards. Use borrowed light through glazed partitions. |
| Single-aspect apartments | All rooms face one direction. No cross-ventilation. Overheating if west-facing. Poor daylight in rooms far from facade. | Require dual-aspect for >= 50% of units (London Plan Policy D6). Single-aspect max depth 8 m, never north-facing. |
| Corridor-only circulation | Long double-loaded corridors (> 20 m) with no daylight, no widening, no social function. Dead space consuming 18-22% of GFA. | Introduce gallery access (daylit), skip-stop sections (Corbusier Unite type), widen at nodes for seating/post. |
| Structural grid misaligned with program | 9 m office grid producing 4.5 m half-bays that are too small for hotel rooms (need 3.6-4.2 m) in conversion or mixed-use. | Establish grid from most constrained use first. Parking (5.4 m module) often governs. Test grid against all programs during concept. |
| Tower-on-podium without wind mitigation | Tall building creates ground-level wind acceleration (Venturi effect) making podium spaces unusable. Lawson LDDC comfort criteria fail. | Chamfer/setback lower floors, add canopies, porous podium edges, wind baffles. CFD testing at concept stage. |
| Anti-Pattern | Failure Mode | Fix |
|---|---|---|
| Over-glazed facades | WWR > 60% causing overheating (> 28C for > 1% occupied hours, CIBSE TM52), glare, high cooling loads, condensation risk in cold climates. | Limit WWR per Section 2.6. Use external shading (brise-soleil, overhangs). Specify high-performance glass (SHGC < 0.25 south/west). |
| Thermal bridging at balconies | Concrete balcony slab continuous with floor slab creates cold bridge. Surface condensation, mould risk, heat loss 15-30% increase. | Thermal break connectors (Schock Isokorb or equivalent). Or structurally independent balconies. |
| Flat roof without redundancy | Single waterproofing layer, no secondary drainage. Single point of failure leads to catastrophic leaks. | Dual membrane or inverted roof. Secondary drainage (scupper overflow) at 50mm above primary. Min 1:60 fall (1:40 preferred). |
| Curtain wall without maintenance strategy | No BMU provision, no cradle track, no accessible cleaning positions. Facade degrades. | Design BMU/cradle system from concept. Max 1.5m reach from cradle. Track loads into structure from Stage 2. |
| Anti-Pattern | Failure Mode | Fix |
|---|---|---|
| Service risers as afterthought | Risers sized for current load only, in awkward locations, no future capacity. Renovation requires destructive work. | Size risers at 130% current requirement. Locate adjacent to cores. Stack vertically through all floors. Access panels on every floor. |
| Acoustic separation ignored between uses | Residential above restaurant/bar: airborne noise (bass/music) and impact noise (kitchen equipment) transmit through structure. | STC 60+ floor assembly. Structural break (floating slab or resilient mount). Vibration-isolated kitchen equipment. Separate structure ideal. |
| Fire compartmentation compromising spatial flow | Fire doors on closers bisecting open-plan spaces. Users prop doors open, defeating purpose. | Use hold-open devices connected to fire alarm (release on alarm). Designate clear compartment lines at natural spatial transitions. Smoke curtains for atria. |
| HVAC zoning mismatch | Single zone serves both perimeter (solar gain variable) and interior (constant internal gains). Temperature complaints, energy waste. | Min 4 perimeter zones (N/E/S/W) + interior zone per floor. Max 50 m2 per zone in cellular office. VAV with individual zone control. |
| Inadequate ceiling void | 150mm void expected to contain HVAC ducts (200-400mm), sprinkler mains (100mm), cable trays (75mm), lighting (50mm), and structure. Physical clash. | Min 400mm distribution void for residential, 600mm for office (BCO), 900mm+ for hospital. Coordinate BIM clash detection at Stage 3. |
| Anti-Pattern | Failure Mode | Fix |
|---|---|---|
| Accessibility retrofitted | Ramps added post-completion to entrances with steps. Clumsy, stigmatizing, expensive. "Accessible" route through loading dock. | Level access designed from concept. Principal entrance IS the accessible entrance. No separate "accessible entrance." |
| Wheelchair refuge blocks stairway | Refuge area encroaches on stair landing, reducing effective width below code minimum during evacuation. | Refuge area: min 760 x 1300 mm (ADA) clear of required stair width. Locate in widened landing or adjacent corridor. |
| Inaccessible upper floors in < 3-storey building | No lift provided because code exempts buildings under certain size. Entire floors inaccessible to wheelchair users. | Install lift regardless of exemption. An accessible building is a better building. Cost: 2-4% of construction budget. |
| Anti-Pattern | Failure Mode | Fix |
|---|---|---|
| All-glass tower in hot climate | SHGC not controlled, no external shading. Cooling load dominates energy. LEED/BREEAM energy credits impossible. | Max 40% WWR. External shading. High-performance low-e glass. Consider double-skin facade with ventilated cavity. |
| Demolish-and-rebuild vs. retrofit | Embodied carbon of new building (400-800 kgCO2e/m2) exceeds operational savings for 30+ years. | Lacaton & Vassal principle: never demolish. Assess retrofit first. Whole-life carbon assessment per EN 15978. |
| Greenwashing with certification | Pursuing LEED points in documentation/innovation while ignoring energy performance. Certified Gold building performing worse than code baseline. | Prioritize energy (EAc2 Optimize) and water (WEc2) credits. Set absolute EUI target, not just relative improvement. Monitor post-occupancy. |
