Northwall is a venture that combines a council-aware feasibility engine with the 22-year, CIAT-accredited architectural practice that has quietly delivered 1,000+ HMO and residential conversions across the South of England.
Most PropTech is built by people who have never picked up a tape measure. Most architectural practices have no engineering capacity for software at scale. Northwall is the bridge.
On the software side, we ship a feasibility engine that turns a UK postcode into an architect-grade compliance report in under five minutes. On the services side, every deliverable is reviewed by a chartered partner whose signature is on the line.
This combination — software speed plus regulated accountability — is what makes British HMO investing accessible to operators who don’t want a side project and to investors who don’t want to do it themselves.
Northwall’s preferred design and delivery partner is Applecore PDM — a CIAT-accredited architectural practice with 22+ years of experience and over 1,000 completed projects across the UK. Their sister company, Applecore Property Services, manages co-living properties on the South Coast and is one of the largest HMO operators in the region.
In partnership with Fareham Building Control · ICO Registered · Client Money Protect · Property Redress Scheme. Coverage: Hampshire, Sussex, Surrey, Dorset and nationwide.
We resolve every UK postcode to its local authority via Postcodes.io, then look up the council in our structured policy library. National HMO regulations and council-specific overrides are applied to generate a risk picture — every flag links back to the source document.
Postcodes.io returns the LAD code, coordinates, and admin district for any UK postcode. Cached at the edge for speed.
We maintain a hand-curated library of council HMO policies, refreshed against the source council page on a rolling schedule.
National HMO Mgmt Regs 2018 baselines are applied, then overridden by council-specific minima where stricter.
Each rule produces a flag with severity (green / amber / red), category, and a citation link to the source document.
For paying Tier-2 customers, every Applecore-stamped output is reviewed and signed by a CIAT-chartered partner.
Planning decisions, build outcomes, occupancy data flow back into the compliance dataset. The library compounds over time.
