RBV-01Plan the layout and buy materialsMeasure the plot and mark out where the beds, path and water butt will go using string lines and marker spray. Before digging anywhere, sweep the area with a cable and pipe detector — old garden pipes and cables sit shallower than you'd think. If clearing a hedge or tree to make space, check with your council for a Tree Preservation Order or conservation area status, and check for nesting birds if it's roughly March to August, since disturbing an active nest is an offence. Buy sleepers, edging, gravel and the water butt kit now so you're not waiting mid-project; budget around £450-£900 total and allow two to three weekends.

KNOW THE RULES

Tree Preservation Orders and conservation area rules are set by your local council — check before cutting. Nesting birds are protected by law roughly March to August; don't disturb an active nest.

RBV-02Build and position the raised bedsFollow 'Build a raised bed from sleepers' to construct and site the beds exactly where you marked them in step 1. If any bed sits close to the house wall or an existing path, check again for buried pipes and cables before knocking in corner stakes. This phase usually takes a full weekend for two or three beds, plus time for the ground to be levelled underneath each one.

KNOW THE RULES

Always check for cables and pipes before driving stakes or fixings into the ground, especially near the house.

RBV-03Lay the edging around the pathsFollow 'Lay garden edging' to install edging along the path lines between the beds, before the gravel goes down. Doing edging before the gravel path means the edging is already firm and in place to hold the gravel in — laying gravel first with no containment just lets it spread everywhere. Leave edging pins undisturbed for at least a day to bed in before walking on them.

RBV-04Lay the gravel pathFollow 'Lay a gravel path' to prepare the sub-base and lay gravel within the edging from step 3, connecting the beds. The most common mistake here is skipping the weed membrane or sub-base to save time — the path then sinks in patches and weeds push through within a season. Allow a full day for prep and another for laying and raking level.

RBV-05Fit the water butt and downpipe diverterFollow 'Fit a water butt with a downpipe diverter' to position the butt near the beds and connect it to an existing downpipe. Before drilling into the wall for the mounting bracket, check for cables and pipes — outside lights, doorbells and outdoor sockets are often wired along external walls. If you also want to run powered lighting or a pump to the beds or shed, that's a job for a qualified electrician: any new circuit is notifiable work under Part P and isn't something to DIY.

KNOW THE RULES

Check for cables and pipes before drilling into any wall. A new electrical circuit is notifiable under Part P — use a qualified electrician.

RBV-06Fill, plant and settle inFill the beds with topsoil and compost, leaving it to settle for a few days before planting — filling and planting the same day often leads to the soil sinking below the sleeper edge. Mulch exposed soil around the edging to cut down weeds, and start watering from the butt once it's had rain to fill it. Give the sleepers a season to weather before they take on the usual grey-brown colour.
