HMO Development

Houses in Multiple Occupation represent one of the most resilient and high-yielding residential investment strategies available in the North West - but delivering a successful HMO requires specialist knowledge that goes far beyond standard construction. Crossfield Development has extensive experience in HMO design, conversion, and new-build, and we understand exactly what is required to satisfy planning authorities, building control, and HMO licensing bodies while delivering a property that tenants actually want to live in.

We work with experienced property investors, portfolio landlords, and first-time HMO buyers alike, taking projects from initial feasibility through to finished, lettable property. Our focus is on delivering HMOs that meet the standards required, attract quality tenants, and start generating income on schedule - because every delay costs you money.

Why choose Crossfield for your HMO project?

Specialist HMO knowledge, not just general building

HMOs have specific requirements around fire safety, room sizes, communal space provision, and facility standards that vary by local authority and property type. We know these requirements across Cheshire East and Greater Manchester and build to meet them —- reducing the risk of failed inspections or costly remediation.

Delivery timelines that protect your investment

Every week your HMO sits unfinished is rental income you're not receiving. We structure our programmes to get your property lettable as quickly as possible without compromising on the quality or compliance that will satisfy your licensor and attract good tenants.

Designed for tenant appeal as well as compliance

An HMO that meets minimum standards but looks and feels cheap will underperform in the rental market. We help you strike the right balance between cost efficiency and tenant-facing quality - the kind of finish that justifies higher rents and reduces void periods.

Experience across conversion and new-build HMOs

We've worked on both HMO conversions - transforming family homes or commercial buildings into multi-let properties - and purpose-built HMO new builds. Whatever your asset type, we have relevant experience and can advise on the most effective approach.

Investor-focused communication throughout

We understand that you're making decisions based on numbers, not sentiment. Our communication is clear, direct, and focused on the information you need to manage your investment - programme updates, cost visibility, and immediate notification of anything that could affect your timeline or budget.

How your HMO project is delivered

  • Feasibility and planning review

    We review the property and your investment brief, assess planning requirements (Article 4 directions apply in many Cheshire and Manchester areas), and give you a realistic view of what the project can deliver, what it will cost, and how long it will take.

  • HMO design and specification

    We work with architects or designers to develop a layout that maximises lettable rooms while meeting all HMO-specific requirements - room sizes, communal space, fire compartmentation, and facility provision. We also advise on the specification level appropriate for your target tenant market.

  • Planning and licensing guidance

    Where planning consent is needed for change of use (C4 or Sui Generis), we support the application process. We also advise on HMO licensing requirements for your local authority and help ensure the finished property meets all conditions.

  • Strip-out and structural work

    Most HMO conversions begin with significant structural changes - removing or adding partitions, installing en-suites, upgrading the electrical supply, and addressing fire compartmentation. We carry out this work efficiently and to building regulations requirements.

  • Fire safety and compliance installation

    HMOs have specific requirements for fire detection systems, fire doors, emergency lighting, and compartmentation. We install all fire safety measures to the required standard and ensure everything is properly documented for your licensor.

  • Fit-out and finishing

    En-suites, shared bathrooms, communal kitchen, and all individual rooms are fitted out to the agreed specification. We focus on durability and practicality as well as appearance - finishes that will stand up to multi-tenancy use and look good for years.

  • Pre-licensing inspection readiness

    Before handover, we carry out our own walkthrough against the licensing requirements to ensure everything is in order. We prepare the property for your HMO licence application and can provide documentation of the works carried out to support your submission.

Our work speaks for itself

Matt is an amazing builder with an amazing attitude. He never ever says “it can’t be done.” He will give it his best and will try to find a way to give you your dream home.

Frequently asked questions about HMO Development

Have a question that isn't answered? Get in touch - we're always happy to talk.

Ask a question
  • Do I need planning permission to convert a property into an HMO?

    It depends on the size of the HMO and where it’s located. Converting to a small HMO (up to six occupants, C4 use) is often permitted development – but many areas of Greater Manchester and some parts of Cheshire have Article 4 directions that remove this permitted development right and require full planning consent. We advise you on this at the feasibility stage so you understand the planning position before committing to a purchase.

  • What fire safety standards do HMOs in Cheshire and Manchester need to meet?

    HMO fire safety requirements are set by the Housing Act 2004 and local authority licensing conditions. They typically cover fire detection systems (interconnected mains-powered smoke alarms and heat detectors), fire doors to all habitable rooms, emergency lighting on escape routes, and specific compartmentation requirements depending on the number of storeys and occupants. We build to these requirements as standard and ensure everything is properly commissioned and documented.

  • How many bedrooms can I fit in my HMO conversion?

    The number of rooms depends on the size of the property, the minimum room size requirements set by your local authority (typically at least 6.51 square metres for a single occupant), the provision of adequate communal facilities, and planning consent where required. We assess all of these factors during the feasibility stage and help you optimise the layout within the constraints.

  • How long does an HMO conversion typically take?

    A standard HMO conversion of four to six bedrooms typically takes between 10 and 20 weeks from start on site, depending on the extent of structural changes, the size of the property, and the specification. We provide a detailed programme in our proposal so you can plan your rental income timeline accordingly.

  • Can you help me understand what specification level is appropriate for my target tenant market?

    Yes – and this is an area where getting it right really matters. An over-specified HMO in a budget market wastes investment; an under-specified one in a professional market leaves money on the table. We help you assess the local tenant demand for your specific area and recommend a specification that optimises your yield without unnecessary expenditure.
