Outdoor Christmas Lights: The Complete Exterior Guide

Most houses are over-decorated and under-designed. The fix is not more lights — it is deciding, before a single light goes up, which line of the building you are drawing.

Start with one line

Look at your house from the pavement at dusk, with the hall light on. The eye lands somewhere: the eaves, the gable, the porch, the bay. That is your primary line, and it gets lit first and best.

1. 1Roofline — eaves, verges and gable edges. It gives the house its silhouette.
2. 2Windows — frames, or bay heads only if the frames are fussy.
3. 3Trees and planting — one specimen tree beats four half-lit shrubs.
4. 4Approach — gate piers, hedging, the run of the drive.

A house with a perfect roofline and nothing else looks expensive. A house with a bit of everything looks like a car park.

By property type

Terraced house

You have one plane and two or three openings, so the whole display is about neatness. A line that dies halfway across the frontage is the most common mistake on a terrace. If the bay has a tiled roof, follow its curve rather than squaring it off.

Semi-detached

The gable is the gift. Follow the verge up one side and down the other, then match it with the porch. Resist lighting the shared eaves right up to the boundary unless your neighbour is doing the same; stopping at the natural break in the brick looks intentional.

Detached

Detached houses can carry a full display: roofline, windows, porch and two trees. Because the building is seen in the round, an elevation that goes dark at the corner is very obvious from a driveway.

Period and listed

Non-invasive fixings only. Stucco and painted render want a warmer, softer light than modern brick, and a slightly lower density so the line reads as a thread rather than a strip.

Modern and new build

Clean fascia lines, generous glazing and pale render take a crisper run. This is the one property type where a cooler white can work, and where a permanent track-mounted system is worth costing.

Density, colour and control

Density

~100 LEDs per metre for an unbroken line at ten metres

Too thin

Below 60 per metre you see individual dots

Colour

Warm white, one temperature, everywhere

Colour as feature

Multicolour on one tree or one porch — never a whole frontage

Control

One timer for the whole display, dusk to 11pm

Warm white flatters brick, stone, stucco and timber, and it photographs beautifully at blue hour.

Fixings: protect the house

Every frontage is different, and the right fixing can only be judged up close, on the day, from the ladder. What matters is the principle: nothing should pierce the cable, and nothing should leave the house marked in January. Non-invasive runs are kinder to the building but more exposed to storm gusts, winter winds and heavy rain, so they need to be planned and checked with that in mind.

Weather

Everything outdoors must be rated for outdoors — the lights, the joins, the transformer and the extension. Keep connections off the ground and out of standing water, use a weatherproof enclosure at the socket, and leave a drip loop so water runs away from the plug. Indoor sets used outside are the single biggest cause of mid-December failures we get called to.

What it costs to have done

That price includes design, commercial-grade lights on seasonal hire (purchase available on request), installation, in-season repairs and January take-down.
