Skylights and rooflights in Northfleet
Northfleet grew up on the south bank of the Thames, around the chalk, the cement kilns and the river trade. Upstairs rooms in terraced and later houses, such as a back bedroom, a bathroom or a landing, often have no good place for a window and can take their daylight through the roof.

Upstairs, where the daylight runs out
-
1 The back bedroom under a low roof A rear bedroom beneath the lower slope of a back addition can have a small window facing a high fence or a neighbour's wall. A roof window above it gives the room a patch of open sky. -
2 A bathroom on an inside wall Bathrooms are often placed in the middle of the plan, where the pipes run, with no outside wall at all. A tube from the roof, or a small window in the slope, gives a room that relies on the switch a source of daylight. -
3 A landing with doors either side Doors on both sides leave a landing with nothing but borrowed light. A unit in the roof over the stairs sends daylight onto the landing and the upper steps below it.

Houses that grew beside the cement works
How a river-and-industry town lays out its upstairs rooms.
Northfleet takes its name from its position on the northern reach of what was once called the River Fleet, now the Ebbsfleet River. Its harbour is a natural inlet of that river into the Thames, and the higher land comes close to the water here, which made it an obvious place for industry. In 1796 James Parker set up kilns on Northfleet creek to make Roman cement, the start of a large complex of cement works along that stretch of the river. Kimberly-Clark's paper mill, which began as Bowaters, dates from 1923. The place became a town in 1874, and an urban district council followed around 1894.
That history decides who lived here and how they were housed. Towns that grew around heavy industry in the 19th century generally filled up with terraces and short rows built close together for a working population. Homes of that type tend to be narrow, with one or two rooms on each floor, a small back addition and a roof that runs front to back over everything. No two streets are laid out alike, so each house is read on its own merits when we visit.
Names for the units in a roof
- Roof window
- A window set in the plane of a pitched roof, opening or fixed, that you look up through.
- Sun tunnel
- A rooftop dome linked by a mirrored tube to a frosted panel set into the room's ceiling.
- Flat roof rooflight
- A glazed unit standing on an upstand of its own above a flat roof deck.
- Diffuser
- The frosted panel that spreads the daylight into the room.
The back bedroom and the bathroom
In a narrow terrace, the back bedroom often sits over the back addition, below the main roof. Its window faces a boundary fence or the flank wall next door, so the light it gets is thin and low. If the roof above has room for it, a roof window in that lower slope gives the bedroom a view of sky and puts daylight on the ceiling and walls. On a house with a pitched back addition the options are wider; on one with a flat roof the answer might be a flat roof rooflight.
In a terrace the roof is shared along the row, so the slope above a back bedroom is a long face of tiles. A roof window there sits between two rafters, and the flashing is cut to the tile course around it. The rear slope is usually out of sight from the street, which keeps the front elevation as it is. Where the back addition has a flat roof, the first thing we look at is the direction of the joists, because the opening is formed between them.
The bathroom is a different problem. Plumbing tends to cluster in the centre of a plan, so a bathroom often has an obscured window on a side wall, or none at all. A sun tunnel in a bathroom is a tube lined with mirror finish that carries daylight down through the roof space from a dome outside to the ceiling below. It suits a small room under a pitched roof where a full window would be out of scale, and the diffuser can sit over the bath, the basin or the door.
Moisture is the other thing a bathroom brings to the choice. A unit over a room with a bath or shower sits in damp air every day, so the lining of the opening, the seal around the unit and the finish on the ceiling all get specified for that. The survey is where we decide what the room needs, including whether the room already has a fan and where it ducts.
The landing
Fitting daylight to the landing helps every other room upstairs, because it is the space everyone passes through. A roof window above the stairwell, set into the slope on the rear of the house, drops light down the top of the flight. The pitch and rafter layout decide the size we can use. Where the roof void is deep or the stair is awkward, a tunnel is the tidier route. Either way, we mark the position from underneath, standing on the landing, and tape the outline on the ceiling so you see where the glow will fall.
The top of a stair gets its light low and from the side. With glass overhead the light arrives from above, so the banister, the wall beside the flight and the steps below all pick some of it up.
Ebbsfleet International railway station on the High Speed 1 line is less than a mile from the town, and Northfleet has its own station on the North Kent Line. Anyone commuting from either station sees their own house early and late, which is when a bright landing, bathroom and back bedroom matter. A tunnel or window that brings in the grey light of a winter morning, before the electric light goes on, is judged at those hours and not at midday, and we think about the room that way when we plan the position.
One last feature of the area is the Blue Lake, a former chalk pit now under water between the A226 and the railway. It is a reminder that chalk workings shaped the ground here. Our concern is the roof and the rooms below it, and at the survey we look at what is above and around the house, the covering, the structure and the access, before any product is chosen.
Whichever room you start with, a loft hatch matters. If we can get up into the roof space, we can see the rafters, the insulation, any water tank and the route a tunnel would take, which turns a rough idea into a firm plan. If there is no hatch, say so when you book, and we will plan to find another way to see the structure.

Gravesham, conservation areas and the drive from Maidstone
Applications in Northfleet go to Gravesham Borough Council. Whether a roof window or rooflight needs one depends on the building and on how the unit sits above the roof, and the conditions are set out in our skylight planning guide. Each condition is measured against the roof over your head during the visit.
Conservation areas near the town
Conservation areas close to the town include the Hill, Northfleet Conservation Area and the Lansdowne Square, Northfleet Conservation Area. A house inside a conservation area still has the permitted development rights it would have elsewhere unless an Article 4 direction has removed them, and our conservation area rooflight guide explains the difference. These are not the only places in the district with a designation, and the boundaries are drawn on the council's own maps, so your address gets checked there at the survey.
If the work needs an application, the choice of unit matters more than usual: how flat it sits to the roof and which slope it is on both carry weight. We discuss those options when we see the roof, and put the preferred one in writing on the quote with the position marked.
Planning is only part of the paperwork. Cutting through rafters or joists also brings Building Regulations into play, covering the framing round the opening and how well the glazing holds heat in, and our Building Regulations guide goes into the detail. Terraced roofs share party walls with neighbours, so we also look at where the opening sits relative to the boundary and the chimney breasts, and plan the work so that the neighbours' side stays untouched.

Swanscombe is about a mile and a quarter west of Northfleet as the crow flies, Gravesend about a mile and a half east and Ebbsfleet Valley a little under two miles to the west. We cover Swanscombe, Gravesend and Ebbsfleet Valley as well, so a road or a neighbour's house nearby is no obstacle to booking.
To start, the quote form is the quickest way in; WhatsApp on 07880 284133 and info@orchardskylightsmaidstone.co.uk reach us too. A line about which room is the dim one, whether the loft is boarded and how you get on to the roof, from a ladder or from inside, gets the visit planned properly and tells us which ladders, tools and sheeting to bring, so the visit answers your questions on the spot.

Bathrooms, landings and dust control
How far is Northfleet from Maidstone?
About 18 miles, heading north-west towards the Thames. We cover the whole area, so the distance is not something you need to plan around.
Do the Hill and Lansdowne Square conservation areas cover my street?
Our conservation area guide explains how the rules apply inside one. Boundaries are drawn by Gravesham Borough Council, so the address is checked against the council's records at the survey.
Our upstairs bathroom is on an inside wall and always needs the light on. What fits?
A sun tunnel from the roof, or a small roof window if the room sits directly under a slope. Which one is possible depends on the distance from roof to ceiling.
Does Gravesham need to hear about a roof window on a terrace?
Sometimes, depending on the house and the unit, and the conditions are in the planning guide.
How do you keep dust out of the rest of the house while a bedroom ceiling is opened?
We agree the route in and out with you first, sheet the floors and the stairs, and close off the room. Furniture in the room is covered, and as much of the cutting as possible is done from the roof side, so the ceiling is opened last and only to the size of the finished lining. We leave the room swept and ready for paint.
What suits a landing better, glass in the slope or a tube through the loft?
The roof space decides. A roof window over the stairwell gives the most light where the pitch and rafters allow it. A tunnel suits a deep void or a stair that sits away from the slope. A landing with a high ceiling over a stairwell tends to suit the window, because the light has height to drop through; a low, flat landing ceiling under a deep roof void may suit the tube.
