Collier Row (RM5) took shape as an interwar suburb of Romford, expanding through the 1920s and 1930s across former Essex farmland. It is a planned residential district rather than a historic village core, with predominantly semi-detached housing, so almost every householder project here is an extension or loft on one of those consistent interwar pairs.

There is no conservation area covering Collier Row — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the uniformity of its interwar suburban roads and by the London Borough of Havering's householder design expectations, which favour keeping the semi-detached rhythm, the gaps between pairs and the original materials intact. We treat that suburban cohesion, rather than a conservation designation, as the reference point when we design an extension.

Demand for rear extensions, two-storey side extensions and hip-to-gable lofts is steady across roads like Mawney Road, Silvermere Avenue and Victoria Avenue, where regular plots and gardens are typical. We check each property's permitted-development position against Havering's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.

Planning in Collier Row (RM5): what to know before you apply

Because Collier Row's suburban roads repeat so consistently, Havering assess extensions against the established semi-detached pattern, so matching original brick, render and roof form and preserving the gap between pairs matters more than on a mixed-typology road. There is no conservation area and no local Article 4 direction, so many houses retain permitted development rights for rear and loft work — but the finite gardens and shared building lines mean depth, height and neighbour impact are the points a householder application is judged on.

Typical Collier Row housing stock

Predominantly interwar semi-detached houses on planned suburban roads, with postwar and modern infill on regular gardened plots. The consistent pairs and generous front and rear gardens are what makes rear extensions, side extensions and hip-to-gable loft conversions the common projects here.

Floor Plans for Collier Row (RM5) homes: the package and the process

Every floor plans we prepare for an Collier Row property is drawn to London Borough of Havering’s validation standards and tuned to the RM5 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Not every project needs a full planning drawing set. If you are selling or letting a property, drawing up a lease, recording a layout before a refurbishment, or simply want an accurate plan of your home, what you need is a floor plan — a scaled, dimensioned drawing of each level, measured directly from the property rather than estimated from an old plan or an estate agent's rough sketch. DrawingsDirect produces floor plans from a laser-measured site visit, so room sizes, wall thicknesses and door and window positions are accurate, not approximate.

Floor plans are commonly used for estate agency marketing and Rightmove or Zoopla listings, for lease plans required by a mortgage lender or solicitor, for landlords documenting a rental property's layout, or as a straightforward existing-layout record before any building work is decided. They are lighter than a full architectural or planning drawing set — there is no design work, no application, and no borough-specific requirements to satisfy — so turnaround is fast and the fee is correspondingly lower. If you later decide to extend, convert a loft or apply for planning permission, the same laser survey can usually be reused as the base for those drawings rather than re-measuring the property from scratch.

What are floor plans used for?

Floor plans serve several distinct purposes in London property: estate agents use them to market a sale or letting alongside photographs, giving buyers and tenants an accurate sense of layout and scale that a floor plan on its own can convey better than photos; solicitors and lenders often require a lease plan showing the demise of a flat within a building, particularly for leasehold sales or re-mortgages; landlords use them to document a property's layout for reference, insurance or portfolio management; and homeowners use them simply to have an accurate record of their existing layout, whether for their own reference or as the first step before considering any building work.

How accurate are laser-measured floor plans?

We measure every floor plan on site using a laser distance meter rather than a tape measure or estimation from photographs, which keeps room dimensions, wall thicknesses and door and window positions accurate to within a few millimetres. This matters more than it might seem: an estate agent's marketing plan that overstates a room's size can mislead a buyer and cause problems at survey stage, while a lease plan used for legal purposes needs to accurately reflect what a leaseholder actually owns. A laser-measured plan also means that if you later want to use it as the existing-layout drawing for a planning application, it is already accurate enough to build proposed drawings on top of, rather than needing to be re-measured.

FAQ

Floor Plans in Collier Row RM5 — FAQs

How much do floor plans cost in London?+
Floor plans start from £450 for a laser-measured, scaled drawing of each floor, with the exact fee depending on the size of the property and the number of floors involved.
How long does it take to get floor plans?+
Most floor plans are ready within a few days of the site survey, considerably faster than a full planning drawing set, since there is no design or application work involved.
Can floor plans be used for a lease or mortgage application?+
Yes — laser-measured floor plans are commonly used as lease plans and for mortgage or re-mortgage purposes; let us know at the outset if you need a specific format or additional detail such as room areas.
Can I reuse my floor plans if I later want to extend or convert my loft?+
Yes — the laser survey behind your floor plans can usually be reused as the existing-layout base drawing for a future planning or building regulations application, saving you from a second site visit.
Do you provide floor plans for estate agents?+
Yes, floor plans are commonly instructed directly by homeowners or via their estate agent ahead of a sale or letting, drawn to scale and ready to use alongside marketing photography.
Do I need planning permission to extend a house in Collier Row?+
Not always. Many Collier Row semis retain permitted development rights, so a modest single-storey rear extension or a hip-to-gable loft conversion can often proceed without a full planning application. Because the plots are regular but finite and the gap between pairs is protected, we check your property's size limits and building lines against Havering's controls first, and prepare a full householder application where the project goes beyond permitted development — as a two-storey side extension often will.
Is Collier Row in a conservation area?+
No. There is no conservation area covering Collier Row. Its planning character is shaped instead by its uniform interwar semi-detached suburban roads and Havering's householder design expectations, which favour keeping the semi-detached rhythm, the gaps between pairs and the original materials intact when you extend.
How much do planning and building-regulation drawings cost for a Collier Row extension?+
We work to fixed fees agreed before we start, with a typical turnaround of around seven days for a standard rear extension, side extension or loft on a Collier Row semi. As a chartered architectural technologist practice we produce the same council-accepted planning and building-regulation drawings as an architect, usually for a lower fee, and include free redraws until your application is approved.
