Rooflights and skylights in Whittlesey

Whittlesey grew up as a market town on the eastern edge of the Fens, and its Friday market in the Market Place has been chartered since 1715 and is still held there today. Behind the shopfronts and the brick terraces that spread out from that square sit the same questions every rooflight raises: how much sky the frame actually holds, whether a bar splits that sky in two, and whether the glass stays clear enough to look through once the novelty of a new opening has worn off.

A rooflight is the only window in a house you look up through rather than out of, and in a town built from its own brick and stone over centuries rather than in one go, that means starting from the roof each house actually has. A Gault brick townhouse off the Market Place, a Fletton terrace further out, or a flat-roofed kitchen extension behind either one, each puts the frame, the bar and the reveal in a different place relative to the bed, the sofa or the sink below it.

Every quote we send for a Whittlesey job comes with a sightline sketch: a drawing of the view from the seat, bed or worktop that matters in that room, done before any brick or slate is disturbed.

None of those three buildings is a typical rooflight job, but they set the tone for how a listed house nearby gets treated. Where a Whittlesey home is itself listed, whether it faces the Market Place or sits a street or two back, listed building consent comes before any new opening is cut, and that consent looks at the rafters and lining inside as closely as the covering outside. That is one reason the sightline sketch earns its keep here: it shows a planning officer, in a single drawing, the structure a rooflight would sit between and the view it would open up, rather than leaving that to be imagined from a specification sheet.

Outside the conservation area, and outside any restriction tied to a particular building, a rooflight can often proceed under the national permitted development rules for roof alterations, provided the unit does not project more than 150 millimetres beyond the plane of the roof slope and the other standard conditions are met. Whether that route is open for a specific Whittlesey address, inside the conservation area or out towards the fen edge, is checked for the address rather than assumed. Building Regulations then apply to the work itself whichever planning route is taken, and we handle the Building Control notification where the job is notifiable.

A rooflight on one of the older roofs around the Market Place, whether stone under Collyweston slate or Gault brick under its own slate covering, usually means a roof window set between the existing rafters, sized to disturb as little of that historic covering as possible. A flush, slim-framed unit keeps the roofline reading as it did from the street, which matters most on elevations a planning officer, and passers-by at the Friday market, actually see.

Behind those older frontages, and across the Fletton terraces further out, many Whittlesey houses have gained flat-roofed kitchen or dining extensions over the years. That is where a flat roof rooflight usually earns its place: an upstand, a fall built into the glazing so rainwater runs off rather than sitting on the pane, and a single unbroken sheet of glass rather than a barred one, seen from a chair a few feet below rather than from directly underneath. The height of that upstand and the depth of the ceiling below both change how much frame shows from the table, so both get measured on survey and carried through onto the sketch.

Where an older rooflight anywhere in the town has already gone cloudy between the panes, that misted look is down to a failed edge seal rather than anything that can be cleaned away. Our misted and failed rooflight replacement service covers renewing the unit to a current specification, and our guide to keeping rooflight glass clear covers the seals and coatings that keep a new one from doing the same thing within a few years.

Where a bedroom or a landing needs a wider opening than the one already there, our guide to upsizing a rooflight opening sets out what that involves structurally, and our reveal shape guide covers splaying the lining so a deep Market Place roof opens the sky out rather than boxing it in.

Can I fit a rooflight in a house on or near the Market Place?

Usually, yes, though the conservation area designated there in 1972 means the design of the unit is looked at closely alongside its size. We check what applies to your specific address with Fenland District Council, and a slim, flush unit set between the existing rafters is the usual starting point.

My house is listed. Does that rule out a rooflight?

No, but listed building consent comes first, and it looks at the roof structure and the ceiling below as well as the glass on top. The sightline sketch we draw at survey shows the rafters the unit would sit between and the view it would open up, which is useful evidence for an application as well as for you.

My house is a Fletton terrace out towards King's Dyke, not near the Market Place. Does the conservation area still apply?

No. The conservation area covers the ground around the Market Place and the north end of Station Road; a terrace further out is very likely outside it, though we still confirm the position for the exact address before naming a product.

Will a rooflight let in too much glare with such an open fen sky here?

It does not have to. Whittlesey's drained, flat fen setting gives a low sun a long run across the sky, so we discuss solar control glass and, on shallow pitches, self-cleaning outer coatings at survey stage, so the extra sky you gain does not come with extra glare.
