Why the gate sets the tone

A garden gate is the first thing a visitor touches and the last thing they see over their shoulder. On a period property it does a second job as well: it either reinforces the age and character of the house or quietly undermines it. A flimsy softwood panel hung between two wobbly posts can make a handsome Georgian frontage look neglected, while a well-proportioned oak or iron gate on a Victorian terrace can lift the whole street. The aim is not to buy the most expensive gate you can find, but to buy one that matches the age, scale and materials of the building it belongs to. That comes down to three things: style, material and proportion.

Read the age of your house first

Before you open a catalogue, walk the street. Nearby original gates — even badly weathered ones — are the best guide you will find, because they were made for houses of the same era and budget. Broadly, the periods point in these directions:

• Georgian and Regency: tall, slender and symmetrical. Square-section vertical bars, simple spear or ball finials, usually painted dark green, black or soft grey. The rails should line up with the banding of the door and windows.
• Victorian: heavier and more ornamented. Cast-iron posts, scrollwork, fleur-de-lys or acorn finials, and gates that sit a little taller than their Edwardian successors.
• Edwardian: lighter, with wider spacing between bars, less fuss and a lower overall height.
• Arts and Crafts and cottage styles: honesty of material. Oak, pegged joints, visible fixings, no applied decoration, and a slightly lower, broader look.
• Interwar suburban: low brick piers with a simple iron or timber gate between them — still the most understated boundary on many a 1930s road.

Get the era roughly right and the gate stops shouting and starts belonging.

Timber: species, construction and proportions

For a pedestrian gate, 900mm wide and between 900mm and 1.2m high is the traditional range; 1.8m is a fence height, not a gate height, and will look out of scale on anything but a very tall boundary. Species matters as much as style. Oak weathers to a soft silver-grey and suits Arts and Crafts and cottage properties, though it needs stainless or galvanised fixings to avoid black rust stains bleeding down the grain. Iroko and other durable hardwoods hold a painted finish well. Good softwood is perfectly acceptable on a painted Victorian or Edwardian gate, provided it is properly primed on all four edges before assembly.

Construction is where cheap gates betray themselves. Look for:

• Framed, ledged and braced construction for a solid gate, with mortise-and-tenon or half-lap joints rather than staples and screws.
• Feather-edge or tongue-and-groove boards on solid gates, with a small gap left between boards so the timber can move with the seasons.
• A diagonal brace running from the bottom of the hanging stile up to the top of the shutting stile. Fitted the wrong way round, it will sag within a year.
• A taper of a few millimetres on the shutting stile so the gate still closes after a wet winter.

Ironwork and fittings that suit the era

Metal gates and fittings should be a shade plainer than you think. Genuine cast iron has a softness and weight that modern tubular steel rarely matches, and second-hand cast-iron gates are well worth restoring if the frame is sound. For a Victorian or Edwardian frontage, hook-and-band or tee hinges in black are correct; for a cottage gate, plain galvanised strap hinges left to dull down look right. Avoid shiny brass on anything pre-1900 unless it is a door fitting. On the latch side, a simple thumb latch, ring latch or Suffolk latch is more in keeping than a modern lever handle, and a small mortice or rim lock at the top of the gate is a discreet way to add security without spoiling the line.

Hanging, clearances and the details that last

Most gate failures are hanging failures, not manufacturing ones. Set posts at least 100mm square, bedded 600mm into the ground in concrete, and always hang the gate on the side that stays fixed and true — never on a post that holds the latch, which takes the slam. Leave roughly 50mm of clearance beneath the gate so it does not drag on gravel or catch on a swollen path, and about 10mm at the shutting stile. Use three hinges on anything over 1.2m or over 25kg in weight. Fit a self-closing spring only if you genuinely need one; on a period property it is better to rely on correctly balanced hinges and a gentle push than on hardware that snaps the gate shut.

Planning, boundaries and upkeep

Boundary rules catch people out. In England and Wales, a wall, fence or gate over 1m high next to a highway, or over 2m elsewhere, generally needs planning permission, and corner plots are treated strictly. If your home is listed, or sits in a conservation area, replacing a gate can require listed building consent or at least a conversation with the conservation officer — original gates are often protected even when they look beyond saving. On upkeep, oak needs nothing but occasional cleaning; painted timber wants a rub down and a fresh coat every three to four years, with particular attention to the top edge and the bottom rail, where water sits. Check hinges and latches each autumn, re-tighten fixings, and clear soil away from the base of the posts so they dry out between showers. Do those small things and the gate will outlast the fence beside it.
