Converted the pub into six apartments, a mix of one- and two-bed configurations. Every commercial-to-residential conversion has four mandatory pre-build checks before the first wall comes down. Skip any of them and the build either legally can't happen or commercially won't pay back:
1) Asbestos R&D survey, destructive sampling at every point where ACM might be present. On The Silver Birch, five of seven samples returned positive. Four were textured coatings in the WCs and most of the first-floor areas. Textured coatings are low-risk non-licensed material, so we removed them ourselves under the appropriate risk assessment and method statement, but the survey is what makes that legally possible.
2) EPC / insulation strategy, minimum energy ratings for let property are set to rise, so the insulation strategy is decided before the build, not after. On an older commercial building like a pub, that almost always means substantial insulation work to the walls and floors. A builder needs to scope this BEFORE quoting, because the U-value targets affect both cost and structural depth.
3) Warranty, Professional Consultant's Certificate (PCC, typically 6 years) from the architect, OR National House Building Council (NHBC) warranty (typically 10 years). Without one of these, the apartments are very hard to sell or mortgage.
4) Sound test / acoustic survey, impact sound, airborne sound, environmental sound, all measured by an expert before the build to determine the sound-proofing needed for the apartments to meet regs and deliver a livable internal environment.
These four are HYPE's day-one commercial-to-residential checklist. We've made an educational HypeTV video walking each of them in detail, link in the build film below.
