HMO ConversionsOne building, multiple lets

A standard property can become a higher-yielding, fully compliant HMO. As HMO specialists, we handle the Article 4 position and run the strongest route to approval, so it earns more for the landlord, investor or developer behind it.

  • A clear yield case to take to your landlords
  • Full planning, or an LDC for an existing HMO
  • Layouts optimised for compliance and the best use of the space

HMO licence applications up 40% since 2018 More landlords are making the switch, and the conversion starts with planning. Read our complete London HMO planning guide

Flat ConversionsOne building, multiple homes

More homes to let and more value in the building. We design house-to-flat splits and manage the full application, from first feasibility to decision.

  • More lettable units from one building
  • Feasibility, planning and building regs in one place
  • Existing, unconsented flats made lawful

Lawful Development Certificates (LDC)Prove lawfulness, protect the asset

Some of the best-earning properties on your patch were converted years ago, without the paperwork. We get the certificate that makes them official, so refinancing, licensing and sales go through smoothly.

  • Existing HMOs and flats certified as lawful
  • Evidence gathering and the full application, handled
  • A clean certificate that satisfies buyers, lenders and licensing teams

Commercial to ResidentialOffices, shops and other commercial units into homes

Many shops, offices and other commercial buildings can become homes without a full planning application. We assess whether the building qualifies, then manage the right route from start to approval, so the landlord or developer has certainty before they commit.

  • Shops and offices into homes, no size limit since 2024
  • Full feasibility on the exact building, so there are no surprises
  • Full planning handled where it is required
