To make an outdoor dining table, build a slatted top from weather resistant timber, fix it to a braced frame, then seal every surface including the undersides and end grain. Cedar, larch, oak and pressure treated softwood are the practical choices in the UK climate. A standard build is 180cm long, 90cm wide and 75cm high, which seats six comfortably and fits most garden patios.
The whole project needs a circular saw or mitre saw, a drill driver, a sander, exterior grade screws and a weekend. The difficulty is not in the joinery: it is in the finishing, because British weather punishes anything left unsealed.
Timber choice determines how long the table lasts and how much maintenance it needs. Western red cedar is light, stable and naturally resistant to rot, though it dents easily. European larch is harder and holds up well outdoors. European oak is the most durable option and the heaviest, and it will silver to a soft grey if left unfinished.
Pressure treated softwood is the budget route and works perfectly well provided you seal it properly and accept a shorter lifespan. Buy it several weeks before you build if you can, and stack it with spacers so it dries evenly. Freshly treated timber holds a lot of moisture and will move as it dries, which pulls a finished table out of shape.
Avoid untreated pine, MDF and any interior grade sheet material. They will fail within a single winter.
Allow 60cm of table edge per person. A 180cm top gives three places along each long side, with room at the ends if needed. If your patio is tight, 150cm by 80cm seats four properly and still leaves circulation space.
Height should be 73cm to 76cm to match standard seating. Measure your chairs or benches first, since outdoor seat heights vary more than indoor ones.
Also measure the patio itself. Allow 90cm behind each chair for someone to stand up and walk past. On a small terrace, a narrower table with bench seating on one side against a wall is often the more workable layout.
The frame carries the load, so build it first and build it square. A simple and reliable design uses four legs made from 70mm square timber, joined by an apron rail set roughly 10cm below the top surface.
Cut the four legs to length, remembering to subtract the thickness of your tabletop slats from the finished height. Cut two long rails and two short rails. Join them with exterior grade screws driven through pilot holes, or with dowels and waterproof glue if you prefer a cleaner face.
Check the diagonals as you assemble. If both diagonal measurements across the frame are equal, the frame is square. Add a corner brace to each inside corner. These small triangular blocks do more for rigidity than any other single component.
Two cross braces running across the width of the frame will support the middle of the tabletop and stop long slats sagging over time.
A slatted top is better than a solid one outdoors because it lets rain drain away rather than pooling. Cut your slats to length and lay them across the frame, leaving a gap of 5mm to 8mm between each one.
Use offcuts of plywood as spacers to keep the gaps consistent. Predrill every fixing hole to prevent splitting, particularly near the ends of boards. Countersink the screws slightly and fill the holes with exterior wood filler, or use stainless steel screws and leave them visible as part of the design.
Always use stainless steel or hot dipped galvanised fixings. Ordinary steel screws rust within months and leave dark stains bleeding down the timber, which is almost impossible to remove.
Once the slats are down, run a sander across the whole surface starting at 80 grit and finishing at 180. Round over every edge slightly. Sharp arrises catch clothing, splinter first and hold finish poorly.
This is the stage that determines whether your table survives. Water enters timber fastest through end grain, so seal the cut ends of every component before final assembly if possible.
You have three main options. Exterior oil such as decking oil or teak oil soaks in, is easy to reapply and needs doing once or twice a year. Exterior varnish forms a hard film that lasts longer but eventually flakes and needs stripping back. Opaque exterior paint offers the strongest protection and lets you choose a colour, though it hides the grain entirely.
For most garden tables, oil is the sensible choice. Apply three coats, allowing full drying time between each, and pay particular attention to the underside. Sealing only the top surface causes uneven moisture absorption, and the table will cup within a season.
Never let bare timber sit directly on soil or gravel. Fit plastic or rubber feet to each leg, or set the table on paving slabs. Ground contact draws moisture upwards and rots the leg ends from the inside.
Adjustable feet are worth fitting on any patio, since laid paving almost never sits perfectly level. A table that rocks under a full plate is a constant irritation and puts stress on the joints.
British winters are wet rather than simply cold, and it is sustained damp that destroys outdoor furniture. If you can store the table under cover from November onwards, it will last considerably longer.
If storage is not possible, use a breathable cover rather than a sealed plastic sheet. Plastic traps condensation against the timber and can cause more damage than leaving the table exposed. Raise the table slightly off the ground and make sure air can circulate underneath.
Reapply oil each spring before the table goes back into regular use. It takes an hour and doubles the working life of the piece.
Making a table is rewarding, but it is not always the practical answer. If you need something that folds away, stacks or resists frost without annual maintenance, a manufactured piece in aluminium, resin weave or treated hardwood will serve you better.
Our range of outdoor garden dining tables UK gardens are built for covers materials chosen specifically for damp climates, and the dimensions are listed so you can check them against your patio before committing. For a coordinated setup, complete modern outdoor garden dining sets UK sale shoppers look for include matched seating, which removes the guesswork around seat and table height.
Shade is worth planning at the same time. A table in full sun is unusable for much of a British summer afternoon, and our garden parasols UK households use over dining areas come in sizes matched to common table lengths. If you build your own top, consider drilling a central parasol hole while the slats are off the frame: it is far easier at that stage than later.
Building the top before the frame leads to a top that does not sit flat. Always build the frame first and fit the slats to it.
Using interior glue is a frequent error. Only waterproof exterior adhesive belongs in an outdoor build. Similarly, filling screw holes with interior filler guarantees they will fail after the first frost.
Fitting slats too tightly is another. Timber swells when wet, and boards butted directly against each other will buckle. The gaps are structural, not just decorative.
Finally, skipping the sanding stage before finishing. Oil and varnish both highlight surface defects rather than hiding them, so the finish is only ever as good as the preparation underneath.
Cutting and assembling the frame takes around three hours for someone reasonably confident with tools. Fitting and sanding the top takes another three. Finishing takes fifteen minutes per coat plus drying time, which usually spreads across two or three days.
Plan the build for a dry spell. Applying oil in damp conditions traps moisture under the finish and leaves a cloudy, patchy result that has to be sanded off.
Whether you build or buy, the same principles apply: the right material, proper drainage and honest maintenance. At Furniture in Fashion we stock outdoor pieces alongside our indoor collections precisely because gardens in this country need furniture chosen with the weather in mind, not against it.
European oak lasts longest, cedar is the easiest to work with, and pressure treated softwood is the most economical. All three perform well provided they are sealed on every face including the underside.
Between 80cm and 100cm. Narrower than 80cm makes it hard to place serving dishes down the centre. Wider than 100cm makes conversation across the table awkward.
Slatted, in almost every case. Gaps allow rain to drain and air to circulate, which prevents the standing water that rots solid outdoor tops from the surface down.
Once a year for most UK gardens, applied in spring. Tables in exposed positions or full sun may benefit from a second light coat in late summer.
You can, but expect a shorter life. If it must stay out, use a breathable cover, keep the legs off wet ground and check for standing water after heavy rain.
