Floor plans that get a Croydon house in multiple occupation licensed — every room measured and scheduled against the amenity standards, the fire escape and compartmentation drawn, and the layout tested against Croydon Council's licensing and planning rules before you submit, delivered in days and revised free until approved, with a free feasibility check first.
Croydon Council granted 84% of the householder planning decisions it made in its latest published year — 3 points below the 87% England-wide householder average. After a wave of garden-grab and back-land intensification, the council reversed course and tightened controls to guard family housing and suburban grain, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Croydon Council needs a full application. Croydon carries at least one Article 4 direction, and conservation areas including Addiscombe (Canning and Clyde Roads), Upper Norwood Triangle and Park Hill remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Croydon is determined against an 8-week statutory target.
Addiscombe (Victorian and Edwardian terraces east of the town centre), Upper Norwood (hilltop Victorian villas around the Triangle), South Norwood (dense Victorian terraces near the lakes), Waddon (interwar semi-detached housing toward the Wandle), Sanderstead (interwar and detached homes on the southern downs) and Thornton Heath (long Victorian terraces off the high street) — these are the Croydon pockets our drawings cover most. Heritage designations here include Addiscombe (Canning and Clyde Roads), Upper Norwood Triangle, Park Hill, South Norwood and Sanderstead. Croydon Council weighs each proposal against Croydon Local Plan and the Suburban Design Guide SPD, where hip-to-gable and roof changes on interwar semis are read against the symmetry of the matched pair. Central Croydon, Addiscombe and Thornton Heath hold pockets of converted flats and small shared houses that sit outside householder permitted-development rights.. On roofs the borough is hipped roofs on the interwar semis and pitched and gabled roofs on the Victorian terraces, over Victorian and Edwardian terraces, interwar semi-detached houses and postwar suburban estates.
A licensable HMO is judged not on how it is built but on how it is occupied, and the floor plan is the document that proves it works. Croydon's Victorian and Edwardian terraces, interwar semi-detached houses and postwar suburban estates include the larger terraced and converted houses that make sound shared homes, and a good layout turns one of them into a compliant, licensable property — each let room the right size, the kitchen and bathroom ratios met, and a protected route out in a fire.
The plan has to speak two languages at once. For licensing it carries a room-by-room schedule: every bedroom labelled with its floor area against Croydon Council's minimum room sizes, the number of sharers each room supports, and the shared kitchen, bathroom and WC provision measured against the number of occupants. For fire safety it shows the escape route, the fire-door and compartmentation lines and the detection layout. After a wave of garden-grab and back-land intensification, the council reversed course and tightened controls to guard family housing and suburban grain, a factor we build into the layout rather than discover at inspection.
Crucially, Croydon operates Article 4 directions in parts of the borough that remove the permitted-development right to convert a family house to a small HMO — Croydon has made Article 4 directions removing permitted-development rights, covering small HMOs across parts of the borough and works in conservation areas such as the Canning and Clyde Roads area of Addiscombe. Where the address falls inside one, you need planning permission for the change of use as well as the licence, and the two are drawn from the same plan.

Every licensable HMO in Croydon — from Addiscombe to South Norwood — needs a licence from Croydon Council; some also need planning permission. You will need a planning application where any of these apply:
We measure every room in the Addiscombe or Upper Norwood house, schedule it against Croydon Council's amenity standards, draw the fire escape and compartmentation, and — where Article 4 applies — produce the change-of-use planning set from the same plan, so the licence and the permission are working from one coordinated layout rather than two.
Below is Croydon Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Croydon approves a solid but more measured share of householder applications, having stepped back from its earlier drive for suburban intensification to protect family housing and the rhythm of its semi-detached streets. Where an HMO needs a change-of-use permission, a plan that already meets the amenity and room-size standards is decided far more smoothly than one the officer has to send back for measurement.

The licence is granted on the layout, so the plan has to answer the licensing officer's checklist before it lands. Croydon Council looks at whether each let room meets the national minimum floor area, whether the kitchen and bathroom provision matches the number of sharers, whether the fire escape is protected the whole way out, and whether the amenity standards for a shared home are met. Across Addiscombe, Upper Norwood and South Norwood these are the checks that decide whether a licence is granted, refused or granted with conditions that cut your rentable rooms.
Hip-to-gable and roof changes on interwar semis are read against the symmetry of the matched pair. We draw the plan to the standards the borough actually applies — mandatory licensing for five or more sharers over three storeys, plus any additional licensing scheme Croydon Council runs — so the layout is tested against the real rules, and where the numbers push it into large-HMO territory we flag the sui generis planning route early.

We draw licensing layouts for shared houses across the borough's rental streets. A few of the Croydon neighbourhoods where HMO plans come up most often:
HMO floor plans for Addiscombe's Victorian and Edwardian terraces east of the town centre — room-scheduled, fire-escape-drawn and tested against Croydon Council's licensing standards.
HMO floor plans for Upper Norwood's hilltop Victorian villas around the Triangle — room-scheduled, fire-escape-drawn and tested against Croydon Council's licensing standards.
HMO floor plans for South Norwood's dense Victorian terraces near the lakes — room-scheduled, fire-escape-drawn and tested against Croydon Council's licensing standards.
HMO floor plans for Waddon's interwar semi-detached housing toward the Wandle — room-scheduled, fire-escape-drawn and tested against Croydon Council's licensing standards.
HMO floor plans for Sanderstead's interwar and detached homes on the southern downs — room-scheduled, fire-escape-drawn and tested against Croydon Council's licensing standards.
HMO floor plans for Thornton Heath's long Victorian terraces off the high street — room-scheduled, fire-escape-drawn and tested against Croydon Council's licensing standards.
A licensing plan is judged room by room. This is what the layout must demonstrate and who checks each part.
| Element | What the plan shows | The test | Checked by |
|---|---|---|---|
| Room schedule | Every room labelled with use and floor area | Each let room meets the national minimum size | Licensing |
| Shared amenities | Kitchen, bathroom and WC provision | Ratios match the number of sharers | Licensing |
| Fire safety | Escape route, fire doors, compartmentation, alarms | A protected route out from every room | Fire / building control |
| Change of use | Existing and proposed use class | Planning permission where Article 4 removes PD (C3→C4) | Planning |
A large HMO for seven or more sharers is a sui generis use that always needs planning permission from Croydon Council, whatever the Article 4 position.
A fixed process built around licensing and fire, so the layout is right before you spend on the application — most HMO plans are ready within days of survey.
Send us your Croydon postcode and how many rooms you want to let. We check Croydon Council's licensing scheme, whether Article 4 pulls in a change-of-use application, and whether the house can meet the room-size and amenity standards.
We measure every room, ceiling height and shared space in the South Norwood property so the schedule is drawn to real floor areas — the single figure a licensing officer checks first.
We produce the scaled plan with the room schedule, amenity provision and fire-escape strategy, plus the C3-to-C4 change-of-use set where Croydon Council requires it.
We package the plan for the licence application and any planning submission, answer the officer's queries, and revise the layout free until Croydon Council grants the licence.
Not always — a small HMO for three to six sharers is often permitted development from a family house, so you may need only a licence. But Croydon operates Article 4 directions that remove that right in parts of the borough, and inside one you need planning permission for the change of use as well. A large HMO for seven or more always needs permission. We confirm which route your Croydon property falls into before you apply. Croydon Council is the decision-maker.
Licensing sets national minimum floor areas — broadly 6.51 m² for a single adult, 10.22 m² for two, with smaller rooms not countable as sleeping space — and Croydon Council may apply its own higher amenity standards on top, which bites hardest on the older houses around Addiscombe and Upper Norwood. Rooms below the minimum cannot be let as bedrooms, which directly sets how many sharers the house supports. We schedule every room to its measured area so you know your true rentable capacity before applying.
Croydon Council needs a scaled floor plan showing every room with its use and size, the shared kitchen, bathroom and WC provision, and the fire-safety layout — escape route, fire doors and detection. The plan is the heart of the application, because the licence is granted on whether the layout meets the amenity, space and fire standards. We draw it to the standard the borough actually applies so it is not sent back for remeasurement.
A shared house needs a protected means of escape — typically a fire-door-lined route from every bedroom to the exit — along with compartmentation between floors and a linked alarm system, all shown on the licensing plan. Croydon Council and its fire-safety inspectors check this closely, because an HMO houses unrelated households who may not know the building. We draw the escape strategy and fire-door lines into the layout so the fire case is made on the plan.
A small HMO houses three to six unrelated sharers and, outside an Article 4 area, is often permitted development needing only a licence. A large HMO houses seven or more, which is a sui generis planning use that always needs permission from Croydon Council regardless of the Article 4 position. The distinction changes both the drawings and the consents, so we establish the intended occupancy in the Croydon property at the outset.
We price each Croydon HMO individually, because the number of rooms, whether a change-of-use application is needed and the fire-escape complexity all vary house to house, and send a fixed, no-obligation quote within one working day. It covers the scaled licensing plan and any planning set with free revisions until Croydon Council is satisfied. The council licence fee is separate. Call 020 7864 7245 to start.
