Timber Pergola & Privacy Screens: Creating a True Outdoor Room

There is a moment on every pergola-and-deck project when the client walks into the finished space for the first time, closes the privacy screen behind them, and stops. It doesn't feel like a garden anymore. It feels like a room — defined, sheltered, purposeful. That quality doesn't happen by accident. It's the result of getting the design sequence right from the start.

The Design Sequence

The most common mistake in pergola design is treating it as an afterthought — fitting a deck, then bolting on a pergola frame afterwards. The structural connection between the deck and the pergola matters enormously. If the pergola posts aren't designed into the deck subframe, the connection is cosmetic rather than structural, and the pergola will move independently of the deck when the ground settles or the timber seasons. The right sequence is: pergola post positions defined first, deck subframe engineered around them, then the deck surface, then the pergola frame, then the screening.

Choosing the Timber

Pergolas in the UK are most commonly built from pressure-treated softwood — either Scandinavian redwood or Scots pine — which provides excellent structural performance at a reasonable cost, and accepts paint or stain well. For a premium finish, we also use green oak, which weathers naturally to silver-grey and has structural properties that require no treatment. The choice affects both the aesthetic and the maintenance requirement over the life of the structure.

• Pressure-treated softwood — cost-effective, accepts stain or paint, moderate maintenance
• Green oak — premium natural aesthetic, weathers to silver-grey, no treatment required
• Thermowood (thermally modified timber) — highly stable, resistant to moisture, good dimensional stability for coastal sites
• All structural connections should use galvanised or stainless steel fixings — never uncoated steel outdoors

Privacy Screens: Function and Form

A privacy screen has two jobs: limiting the sightlines into the space from neighbouring properties or public areas, and creating a sense of enclosure that makes the space feel intentional rather than just outdoors. The most effective screens are those that are fully opaque at seated and standing eye level — typically from about 0.9 m to 1.8 m above deck level — but open or semi-open above that line to allow light and air movement.

For our Granite Mayfield deck board project paired with the timber pergola, we designed a vertical timber screen with a slatted upper section — providing privacy at eye level while allowing airflow above. The proportions of the slats (narrow gaps, wide boards) were chosen to align with the deck board profile, creating a visual coherence across the whole composition.

The Hot Tub Integration

Pergolas and hot tubs are a natural pairing — the pergola provides shade from summer sun and shelter from light rain, while the privacy screen means you can use the tub without entertaining the neighbours. The structural requirement for a hot tub integration is a reinforced pad within the deck — typically a concrete pad poured at the same time as the post bases, or a steel-supported platform within the subframe. A filled hot tub typically weighs 1,200–2,000 kg; that load must be designed into the structure from day one.

"Natural timber, smooth lines, and a modern privacy screen come together to create a space you'll never want to leave."

What Does a Pergola Cost in Devon?

A bespoke timber pergola with privacy screening, combined with a composite or PVC deck, typically falls in the range of £8,000–£20,000 depending on size, materials and complexity. Projects with hot tub integration, lighting or electrical will add to that range. We provide itemised, transparent quotes after a free site survey — so you know exactly what you're paying for and why.
