Skylights and rooflights in Purfleet-on-Thames
Purfleet-on-Thames lies between the A13 and the river, and forms part of the Thames Gateway redevelopment area. A hall, a box room or an extension that daylight struggles to reach can be lit from the roof.

Winter mornings, late afternoons, dusk: when Purfleet rooms run dim
-
1 December before work The c2c line takes people from Purfleet station towards Fenchurch Street, and for months of the year the morning starts in the dark. A hall or landing with no window of its own stays dim long after sunrise, and a roof window over it brings in the first of the day. -
2 Late afternoon in a kitchen extension A single-storey extension with side walls close to a boundary loses its low sun early in the day. Glass in the roof catches what is left of the sky after the walls have stopped delivering it. -
3 Dusk in the box room The smallest bedroom usually has one small window and a loft directly above it. Add a desk and a lamp-free afternoon is out of reach, so the roof is the place to look for more light.
Between the A13 and the river
A narrow band of land with a long industrial and military past.
The A13 forms the northern edge of Purfleet and the Thames the southern one, and the town sits just inside the eastern end of the M25, outside the Greater London boundary. Some industry lies to the south, and the area forms part of the Thames Gateway redevelopment area. Scania's largest European workshop and office is also here. For us, that mix of old and new matters because we cannot guess a roof from a postcode. Someone near the station might live in a flat; a few streets away it could be a house with a loft; and the two need different handling before a rooflight is even discussed.
What we check on a Purfleet visit
- Which way the glass faces Orientation decides how much sun and how much steady sky light the unit gets.
- What sits beneath it Tiles, felt, lead or slate over rafters or joists, and the ceiling below.
- What the roof void holds Insulation, services, ductwork and the head height to the room.
- What kind of building it is House, flat or conversion, which settles whether planning rights apply.
Flats, houses and the question of rights
Householder permitted development covers houses. Flats and maisonettes do not have those rights, and nor do houses made by converting commercial or farm buildings under change-of-use permitted development. A redevelopment area can bring blocks, conversions and newer terraces alongside older houses, so we ask early what kind of building you are in. If you own a flat or a converted property, our skylight planning guide explains why a planning application may be the first step and what to ask the council.
The magazine and the garrison
Purfleet's history includes its Royal Gunpowder Magazine, established in the 18th century with a garrison to guard it. The magazine itself dates from 1781 and has room for 60,000 barrels of gunpowder, and J. M. W. Turner sketched the powder magazines here between 1805 and 1808. It is a reminder that this stretch of the riverbank has been put to many uses, and that buildings change purpose over the decades. When a property has been altered, or a loft or outbuilding has been converted, we want to see the planning history before we draw anything.
What we read on the way in
On a first visit to a house in Purfleet, four things shape the rest of the conversation. The direction a roof faces decides how bright the sunlight is under the glass at different times of day. Next comes what lies directly beneath the glass: a tiled slope over a loft, a flat felt roof over a plasterboard ceiling, or a lead valley between two rooms. Then we look at the loft or roof void, since a sun tunnel, a roof window and a lantern ask very different things of it. Last comes the building type, which settles the planning route.
A kitchen extension built to the side of a house shows the point well. Its roof is usually flat, it sits close to a fence or a neighbour's wall, and the window it was designed around sees only a strip of sky. Light from above reaches the worktop and the dining end equally, and the flat roof is easy to open. A lantern is a different matter: on a flat roof it normally rises beyond the 150 mm that Class C allows, which usually makes it a planning application unless Thurrock Council says otherwise. The details are in our roof lantern planning and Building Regulations guide.
The box room, the hall and a day on the c2c
Small spaces at the centre of the house are where roof light does the most.
Railway services run from Purfleet station to London Fenchurch Street, Barking, Grays, Tilbury and Southend, and a household that depends on them has a day with a particular shape. Out early, back after dark in winter, and the house is at its brightest when nobody is in it. For the people who work from home on other days, the room that gets turned into an office is usually the one nobody wanted to sleep in: the box room.
Which word means which product
- Roof window
- Sits level with the roof slope around it, flush with the tiles or slates.
- Rooflight
- A glazed unit set on a kerb or upstand, out of plane with the roof surface. A roof lantern is one.
- Sun tunnel
- A small roof dome connected by a reflective tube to a diffuser set in the ceiling below.
- Landing
- The upstairs space between the stairs and the bedroom doors, often without a window.
Why a box room is dim
A box room is the third bedroom, and it is usually the smallest. It often has a single window of modest size, and the door opens onto a landing that has no outside wall of its own. The room is used for a desk and a shelf, and the lack of daylight shows by the middle of the afternoon. When the house has a pitched roof and a loft above, glazing in the slope directly over the room can add more light than a second wall window could. If a loft hatch sits in the way or the loft is boarded, a sun tunnel brings daylight through the void from a small dome on the slope.
Landings and halls
The hall and the landing are the two spaces that connect every room, and their only light is borrowed from the rooms around them. A roof window over the stairs lights both floors at once, because the daylight travels down the stairwell. We check what the roof structure allows and whether the stairs, the landing and the loft hatch line up. Where they do not, a pair of smaller units can do the job.
A new roof window is building work. The structure around the opening has to carry what the cut rafters carried, and the glazing must meet the energy standard for its type, which for a new or replacement roof window is 1.4 W/m²K or a Window Energy Rating of band B at minimum. We handle the Building Control notification where the work is notifiable, and our Building Regulations guide goes through the details. For a loft that people sleep in, escape adds a further question, and the guide covers that too.
The conservation area on the map
Thurrock Council lists a Purfleet conservation area on its conservation areas page. A conservation area does not by itself remove permitted development rights for a rooflight on a house; an Article 4 direction does. If an application does turn out to be needed, the design of the unit and the slope it sits on carry more weight. Your address goes through the council's records at survey, before any price is fixed. Our conservation area guide explains how the rules apply.
Garden rooms, flat roofs and who signs it off
Planning questions for Purfleet-on-Thames go to Thurrock Council. Any question about changing how the outside of a house looks goes to the council, and the way the work is built is a separate matter that falls under the Building Regulations. A registered building control approver or the council's own team signs that side off.
| Roof over the room | Unit that usually suits | To settle first |
|---|---|---|
| Flat roof against the house wall | Flat rooflight or roof lantern | Upstand height, drainage falls and whether planning applies |
| Mono-pitch sloping away from the house | Roof window in the slope | Rafter spacing and the pitch of the slope |
| Shallow pitched roof over a link | Sun tunnel or small roof window | Head height and what is in the roof void |
A garden room as a new room off the house
A garden room that opens straight from the kitchen or living room often has a flat or shallow mono-pitch roof with a wide bank of glass doors facing the garden. It is bright near the doors and gloomy where the room meets the old house wall, and the joint between the two is where a rooflight does its best work. A flat rooflight set a little way in from the house wall will bring light back into the older room as well as the new one. Where the garden room stands apart from the house, its size, its distance from the boundary and the way it is used all change which rules apply, so we ask for those details first.
Fitting glass in a flat roof starts with an upstand or kerb, built to a height that suits the roof covering and the drainage. Heights and falls are set out under upstands and kerbs. A rooflight has a less demanding energy limit than a roof window: the limit for a rooflight or lantern in an existing dwelling is 2.2 W/m²K.
Choosing the unit for the roof you have
For a flat roof, flat roof rooflights are usually the simple answer. For a deeper opening, a roof lantern gives a taller glazed form and more daylight at the sides of the room, though it normally needs planning permission. Sun tunnels suit a link space or a small cloakroom. Anything that makes a hole in the weather layer is checked for the build-up of the roof beneath it, because the way the deck is insulated governs the detail at the upstand.

Flats, hallways and garden-room lanterns
Our flat is near Purfleet station. Can we fit a roof window?
A flat or maisonette falls outside householder permitted development, so a roof window usually starts with a planning application to Thurrock Council, and the building's freeholder or management company may also have to agree. Our planning guide explains how to tell which route applies, and we check the building type at survey.
What would you fit over a hallway that has a loft above it?
A sun tunnel is the simplest answer where the loft is full of insulation and boarding, and a roof window directly above the stairs works where the loft can be opened up. Which one suits depends on the height from roof to ceiling and on what runs through the void.
Is a lantern over a garden room worth the planning application?
A lantern on a flat roof normally rises further than Class C allows, which usually means a planning application. A flat rooflight sits lower, and on a house it can stay within permitted development if it projects no more than 150 mm. We compare both against your roof at the survey, and the lantern planning guide explains the difference.
