Skylight and rooflight fitting in Hawkhurst

Hop growing left Hawkhurst with its oast houses, and over 200 listed buildings stand across the parish. Rooms in buildings of that kind often sit a long way from a window, and a roof can bring daylight down to them.

Hawkhurst buildings by era, and where each loses light

  1. A dim dining room in the middle of a house, light only at the far doorways
    1 Hop-era oast houses The oast houses outlived the hop industry. Buildings made for drying hops tend to have few, small openings, so where one has become a home, a hallway or stair can sit far from any glass.
  2. A deep through-lounge, bright at the garden doors and gloomy by the bookshelves
    2 Older listed houses With over 200 listed buildings across the parish, listing is the first question we raise on a roof here.
  3. A long, dark hallway with one small window at the far end
    3 Extensions added later A rear extension on a house of any age can cut off the room behind it. A rooflight in the new roof sends daylight back towards the old wall.

Oast houses and old farm ranges

Hop growing gave the area a skyline of hop gardens and oast houses. Mechanisation and cheap imports ended the industry eventually, but the oast houses remain. A building made to dry hops has thick walls and few openings. Once it becomes a home, the rooms that used to be kiln floor or store can sit a long way from the outside wall.

The hallway is where we meet this most. In a converted range the stair often rises through the middle of the plan, with bedrooms and living rooms leading off it. There is no wall for a window, and the hall relies on whichever door happens to be open. A roof window over the stair gives it a source of its own, and a deep loft calls for a sun tunnel with a long tube. Roof pitch together with the framing behind the plaster chooses between the two, and we study both inside the building itself before recommending one. Photographs of the hall and the stair help us prepare, and the final call comes on site.

Terms for converted farm buildings

Oast house
A building made for drying hops, with a kiln and a roof vent, and a feature of the skyline around Hawkhurst.
Change of use
Turning a building made for another purpose, such as a barn or an office, into a dwelling.
Householder rights
The permitted development rights that let an ordinary house add some rooflights without an application.
Decision notice
The council's written permission, listing any conditions attached to a conversion.

How the conversion happened

Ask any owner of a converted farm building how it became a house and the answer changes what we can do. Suppose an oast or barn became a dwelling through change-of-use permitted development: householder permitted development rights never came with that house, and a rooflight there goes to the council as an application. Full planning permission for the conversion is a different case, since the householder rights stay unless a condition on that permission took them away. The decision notice settles that, and we ask to see it at the survey. The planning permission guide has the full list of conditions.

Inside the kiln end

The tower end of an oast often becomes a round or square room, with a roof that rises to a point. Rooms like that hold their own difficulty: the wall is curved or thick, and the usual window shapes do not follow it. A roof opening in a conical roof is a different job from one in a plain slope, and we look at the timbers before suggesting anything. Where the roof geometry allows only a small opening, a sun tunnel can take daylight to a room below without a large cut.

Tall roofs and what they carry

The pitched roofs of an old range are often steep, and the timbers under the tiles were laid for the load of tiles and nothing more. A new opening needs its own framing, and the trimming around it is worked out before the first tile comes off. In a converted building the insulation and lining added during the conversion also matter, because the new unit has to sit properly through every layer, and we check those layers at survey.

On the garden side of an old range the roof slope may be the only face of the building that was never given a window, which makes it a natural place for one. A roof window set into that face lights the room below, and the lane side of the building stays as it was.

Old ranges often have chimney stacks and flues running up through the roof, and the position of a unit has to keep clear of them. We trace the stack and the flue from the loft before marking the slope.

Wooded ridges and the light under them

Hawkhurst parish lies in the High Weald, characterised by sandstone ridges and steep-sided valleys that are typically wooded and cut by gill streams. A house on ground like that can lose the open sky a house on a flat plain would have. Trunks and branches stand close to the walls, and the ground may rise behind the house to the height of the first floor. Side windows in houses of that kind can end up looking at foliage or a bank, and the daylight they pass in is a small share of what is above the roof.

That is the reason a rooflight can be worth more here than the same unit on an open plot. A pane in the roof looks up past the lowest branches to the sky. We check the aspect on site, because a roof under a heavy canopy is a different job from one that clears the treeline, and the product follows: glass on a flat deck, a window set in a slope, or a sun tunnel.

Dim places in a wooded-site house
RoomWhat cuts the lightRoute from the roof
Hallway or stairNo outside wall at the core of the planRoof window over the stair; sun tunnel through a deep loft
Garden roomWalls facing trunks and shadeFlat rooflight or lantern on the garden-room roof
BathroomSmall frosted window, or noneRoof window; sun tunnel where the roof is pitched but the loft is awkward

Low sun matters on a hillside. On a steep-sided valley the sun may clear the ridge late in the morning and drop behind it early in the afternoon, and the walls of a house facing the slope can lose direct light for hours. Roof glazing takes in whatever sky is left. We note the ridge line and the tree line as part of the aspect at survey.

The garden room under the trees

A garden room or conservatory on a wooded plot has glass in its walls and often still feels dim, because the walls face trunks and shade. Glazing in the roof draws on a wider angle of sky. A flat garden-room roof can take a low rooflight or a lantern, fitted while the roof is being re-covered. Where the roof is pitched, the rafters and the lining dictate the size of opening.

Leaf fall matters up here too. A rooflight under overhanging branches collects debris, and we plan its position with access for cleaning in mind. A pitched roof window can be reached from a ladder, while a unit in the middle of a wide flat roof may need a different approach.

Weather comes with the site. A roof on an exposed ridge takes wind and rain from directions that a roof in a valley does not, and flashings are sized and fixed for the position. We plan the weathering of every opening for the roof it goes into.

Hallways, landings and the bathroom

The same logic applies to the inner parts of a house. A bathroom against the party line or the hillside may have a small frosted window at best, and a roof window set at the right height brings in daylight and lets steam out. Landings sit between rooms on every floor, and a landing with a roof window above it lights the stairs below as well.

Where the loft above a landing is deep, the roof window and the ceiling opening sit a long way apart. A boxed light shaft joins the two, framed between the rafters and the joists and lined inside, and a deeper loft means a taller shaft. The length of that run is one of the first measurements we take from the loft.

The village lies at the intersection of the A229 and A268, and the nearest open station is Etchingham. Materials and glass arrive by road, which is why we ask early how wide the drive or lane to your door is.

Working in an older building

In a building with hundreds of years behind it, we open nothing until we know what is under the tiles. The survey records the covering, the timbers, any old insulation and the position of chimney stacks and flues, and where an unusually thick wall or stair sets limits. A bathroom roof window, for example, has to clear the ceiling joists and still leave room for lining.

Cutting a new opening in the roof is building work, so we handle the Building Control notification where the work is notifiable. The ten-year workmanship guarantee comes in writing at the end.

Planning history in the file

Older buildings tend to have long planning histories: extensions, conversions, a barn turned into a dwelling. Any of those can carry a condition that bears on a roof opening. If you hold a decision notice for your building, bring it to the survey. If you do not, the council keeps the record, and we can tell you which entries matter for a rooflight.

Oast conversions, listing and the hall

We bought a converted oast house. Which rules apply to a new roof window?

How the conversion came about decides it. Where change-of-use permitted development created the house, there are no householder rights to use, and the rooflight goes to the council as an application. Where full planning permission created it, the rights remain unless a condition removed them, and the decision notice shows that.

Does Hawkhurst sit outside your survey area?

Hawkhurst lies due south by road, about 18 miles from Maidstone. We can usually look at the roof, the loft and the dim room in a single stop at the house.

Our cottage is listed. Can anything go in the roof?

A new or altered roof window on a listed house almost always needs listed building consent from Tunbridge Wells Borough Council. The type of unit, its size and the slope it sits in all feature in that decision. Our guide on rooflights on listed buildings explains the process.

The hall in our house has no window at all. What can go in the roof above it?

A roof window works when the slope is close to the stair. Where the loft is deep and a window would sit too far off, a tube-type sun tunnel takes over. The pitch, the rafter spacing and what the loft holds make the choice, and the survey records all three.
