Up the hill
Roofs on the ridge above Newbury
Cold Ash is a village on a ridge north-east of Newbury, with woods and open common close by and a mix of older cottages and houses from the twentieth century. West Berkshire Council handles planning questions. Roofs here are often large and rooflights often go in sets, so the work is as much about layout as about any single window.
Stage 01 · Trees and slopes
Wooded lanes and houses with room to spare
Houses in Cold Ash tend to sit on larger plots than those in town, set back from lanes lined with trees. Many were built across the twentieth century, some as individual homes and some in small groups, and there are older cottages among them. The roofs are often bigger than average, with hips, gables and long slopes that offer plenty of space for glass.
The shape of the roof changes the layout. A hipped end has no gable wall to put a window in, so the daylight for a room under it has to come through the slope. A long slope can take two or three units spaced along its length, while a short one may only have room for a single window between the chimney and the eaves. We draw the options at the survey and the numbers come afterwards.
Trees matter on a roof like this, and Cold Ash has plenty of them. Branches over a slope drop leaves and needles into the gutters and around a frame, and they cast shade that changes which slope is worth lighting. At the survey we note what overhangs the roof and think about where a unit will actually receive daylight.
From the lane the roof is on show, so how the windows look together counts for something. Frames set at the same height and spacing look intended. The plan includes a simple sketch of the pattern, so you can see it before any work starts.

Stage 02 · Old windows
Replacing a unit that has seen its day
A good number of Cold Ash houses already have roof windows from a past conversion, and some are now tired. Seals fail, glass mists and frames show their age. Replacing one is usually simpler than starting from a bare roof, because the opening exists, though the new unit has to suit the old rafter positions.
Every roof window has a data plate, usually on the inside of the frame, stamped with a short code. On a VELUX the first letter gives the width and the numbers after it give the height, which is why an MK04 and a CK02 are different shapes. Older numeric codes such as 104 or 206 correspond to current ones, and we look up the match before ordering. The old VELUX size guide shows how old and new codes line up.
A full swap of frame and glass counts as notifiable work for Building Control, whereas changing just the sealed glazing unit does not. Which applies depends on what has actually failed, and the survey settles it. A misted pane may need nothing more than a new glass unit, which costs less than a whole new window. A new roof window has to meet the Part L figure for existing dwellings: no worse than 1.4 W/m²K, or a rating in Band B on the Window Energy Rating scale. The manufacturer's data sheet gives the number for the unit chosen, and it goes into the plan.
| What to find | Where | Why it matters |
|---|---|---|
| Data plate code | Inside the frame | Gives width and height |
| Glazing condition | Between the panes | Decides unit or full swap |
| Flashing type | Round the frame outside | Must suit the covering |
| Opening style | Handle position | Top-hung or centre-pivot |
Stage 03 · Loft rooms
From storage space to bedroom, step by step
The loft is the biggest factor on a house of this size, and it can be the largest unused room under the roof. A deep, wide roof space allows a proper conversion, with a room that has more than one window. It also means more rafters to cross, so the exact positions of the frames are drawn on the plan against the real timbers instead of being guessed from below.
A conversion involves more than windows: a stair, a floor that carries the load, insulation and fire safety. The skylight is the part we fit, and we say plainly where the other trades come in, so you can ask for their quotes in the right order and in good time.
If the house already has two storeys, the stair to the new room must be protected, because the way out from that height cannot be a roof window. For a single-storey home or a chalet within the 4.5m limit, the same window may be the way out. That single fact shapes the whole layout, so it is settled early.
An opening unit helps to air the room and may cut down condensation, and a blind keeps it dark for sleeping. Blinds for roof windows are made to fit a given frame, so the size code decides which ones are available, and the plan lists the colour and fabric ahead of the day.
What shapes a loft room job
| Stair | Position, protection and headroom |
|---|---|
| Floor | Strength to carry a bedroom |
| Windows | Number, size and opening style |
| Insulation | Between and under the rafters |
| Finish | Plaster, lining and decoration |
The quote covers our part and names the trades we expect to work alongside.
Stage 04 · Group estates
When one condition covers a whole close
Houses built together often share the same planning history. If the permission for a small estate removed permitted development, every house in the close has lost its householder rights, including the right to add a rooflight without an application. That is easy to miss because the house looks like any other.
Such a condition is printed on the original consent for the development, held in West Berkshire Council's planning register. We search for it before quoting. If one applies, the plan makes clear that an application is required, lists what to send in and we can supply the drawings that go with it.
The North Wessex Downs National Landscape lies nearby, and part of Cold Ash may sit inside its boundary, which is a point to confirm with the council rather than assume. On land of that kind some householder freedoms are narrower, yet a house can still have a rooflight. Whatever the council replies goes into the plan, and the planning guide describes the general rules.
Often the answer is simply that nothing needs applying for, and the plan says so in a line. Where an application is wise, you know before the unit is ordered, and the lead time is counted from the day the consent arrives.
No condition on the house
- National rules usually apply
- No application normally needed
- Listing and directions still checked
- Plan records the council's view
Condition on the estate
- Householder rights removed
- An application is needed first
- Drawings prepared with the unit
- Order waits for the consent
Stage 05 · Lanes and drives
Reaching the roof on a busy lane
Cold Ash lanes can be narrow and lined with parked cars, so we agree where the van and any scaffold will stand before the day. Gravel drives and long approaches are easy enough, though they affect how the unit is carried, and a long walk from the gate to the house is noted for the team. A side gate too narrow for a frame is noted as well, so the unit comes in through the house or over a plank and is not forced.
Dates are fixed when the order is placed. A standard window is quick to arrive while a made-to-size unit takes longer, and the plan gives an estimated delivery and the day we come. If the job needs Building Control, we file the notice and the plan names who inspects. On a house with a long approach, the glass may arrive at the gate hours before it is needed, and the plan says where it waits and who minds it until the team is ready.
Leaves matter on the day too. A roof under trees can be slippery and covered with debris, so it is swept clear before work begins, and the gutters beside the new frame are cleared at the end.
