If you’ve ever tried measuring your own windows and ended up with a headache and a tape measure jammed behind a radiator, welcome to the club. Unusual window shapes are more common than people think and yes, you can absolutely have shutters.
The problem with ‘standard sizes’
Many UK homes, especially older or extended properties, have windows that weren’t designed with off-the-shelf anything in mind. Bay windows with odd angles, deep sills, sloped ceilings, or shaped tops like arches or triangles, these all need a proper plan, not guesswork and filler strips.
Where most go wrong
A lot of people assume shutters won’t work for shaped or awkward frames, or worse, they try to fit standard products and hope for the best. This often leads to poor insulation, light leakage, gaps that collect dust, or just something that looks like it doesn’t belong there.
How we handle it at Shutter Envy
Our survey team brings over 15 years of experience to every job. We don’t eyeball it. Every measurement is taken on-site with pro-level tools, accounting for depth, angles, window type and movement range. If it tilts, curves, bows or bulges, we’ve likely seen it before.

Once measured, your shutters are made to fit with millimetre precision, using your choice of louvre size, tilt mechanism and material, from hardwearing MDF to waterproof ABS or luxury hardwood.
Common specialist fits we handle include:
- Bay windows (Box, Bow, and those creative 1980s hockey-stick shapes)
- Apex windows (great in lofts, even better with the right louvre angle)
- Arched, circular and even porthole-style windows
- Split-level café style and tier-on-tier for sash frames
They just work
Beyond the visuals, shaped shutters improve energy efficiency and help manage light in a way curtains or blinds can’t. That odd-shaped window that’s been making your lounge feel like a greenhouse in summer? We’ll sort it.
If you’ve got a tricky window and were told shutters aren’t possible, we’d love to prove that wrong, with tape measure in hand and a smile on our face.
