Tenement, Flat & Balcony Growing in Scotland: What Actually Works

Growing food in a Scottish tenement or flat comes down to four things you sort out before you choose crops: permission, weight, wind and water. On a shared back green the titles and the other owners decide what you can build. On a balcony, the structure decides how much weight it can carry. With no outdoor tap, you either carry water or cut how often you need to water.

Who owns the back green, and who can say yes

Check the title deeds first, because they control the arrangement. Back greens are typically common scheme property, so all owners share the maintenance costs, while front gardens are usually owned solely by the adjacent ground-floor flat. Where titles are silent, the Tenements (Scotland) Act 2004 provides default rules: an outdoor area belongs to the owners of the bottom flat nearest to and adjacent to it. Unless the titles say otherwise, if the part you want to alter is owned partly by another flat or in common, you need express consent from the other owners. Real burdens are listed in section D (Burdens) of the title deeds and typically set out how your flat can be used and what changes can be made, for example structural alterations needing consent. Normally they are enforceable by all the owners, so it is advisable to obtain consent even for minor alterations.

Where the Tenement Management Scheme applies, scheme decisions are made by the owners with one vote for each flat, and maintenance does not include alteration or improvement. A raised bed, a greenhouse or fencing off a section is an alteration, so raise it with the other owners, in writing, before building. A written approach to neighbours first is usually enough to start the conversation, and no vote has to be called to begin. Consent from co-owners is separate from local authority consents: in a listed building or conservation area you may need listed building consent, and a valid planning consent does not remove that need (Under One Roof). If in doubt, ask a solicitor.

A property factor is employed to act on all owners' behalf to manage the common property: repairs, inspections, insurance and contractors, though the owners remain responsible for keeping the common parts up to standard. Factors must follow the code of conduct under the Property Factors (Scotland) Act 2011, which covers their conduct and complaints, not whether you can plant. So the order is: check the titles, get the owners' consent, then let the factor administer what has been agreed.

Once there is agreement, see setting up a raised bed on a shared tenement back green. If the answer is no, or there is no back green, an allotment is a separate route, though waiting lists can be long in the larger cities, so ask the council or an allotment association early: see getting an allotment.

If you are renting

The Scottish Government model private residential tenancy agreement says the tenant must get the landlord's written consent, in advance, before making any alterations to the property. If the let includes a garden solely for your use, you must maintain it in a reasonable manner. The Housing (Scotland) Act 2025 will give tenants greater rights to personalise and decorate their home after six months, including larger changes that landlords cannot unreasonably refuse, but no date for that has been set. For now, ask in writing before putting anything on a balcony or into outdoor space, and keep the reply.

Weight

Containers full of compost and plants weigh a considerable amount, as do people using the space. RHS advises establishing what a balcony or roof can take with a chartered structural engineer or a surveyor. Balconies suspended out from the building have strict weight restrictions. Place heavy containers near load-bearing walls or over a load-bearing beam or joist, which take more weight than unsupported areas.

Make containers lightweight with ample drainage holes, and put a layer of lightweight drainage material at the base. Lighter peat-freeCompost made without peat, which is harvested from a slow-forming, carbon-storing wetland habitat that peat extraction damages. Full definition → mixes weigh less than soil-based composts, which are heavier but hold water better (RHS). Terracotta and stone are heavy and can crack in hard Scottish frost, so plastic, metal and fibreglass suit a balcony. On a shared back green, several large raised beds, a full water butt or paving slabs are the kind of change to raise with the co-owners first, because some back greens sit on old paving over drainage. If an older back green shows cracking or subsidence, get a structural engineer to look at it, and more than one quote.

Wind

Strong winds and sunshine are the main limitations of roof gardens and balconies, and an upper-floor balcony is the most exposed. Light containers in exposed positions may need fixing so they do not blow over in strong winds (RHS); several smaller pots grouped against a wall are steadier than one tall one. Use any existing shelter from walls or fences. Solid walls can cause turbulence on the leeward side, so slatted or mesh screens that filter the wind make a better microclimateThe local growing conditions in one specific spot that differ, sometimes substantially, from the wider area's average climate. Full definition →. Containers dry out rapidly in windy, hot weather, so choose a good width and depth. A Juliet balcony or railing with no floor space suits rail-mounted planters, hanging baskets or an indoor windowsill box, which are lighter and sidestep the weight question; fix them securely. See best crops for a windy Scottish balcony.

Water without an outdoor tap

Rainwater harvesting needs a gutter with a downpipe or a downpipe kit, so on a balcony or upper floor without one, carry water from an indoor tap. Where there is a standard round downpipe, a slimline water butt with a diverter can fit, though check the fitting before buying. On a shared back green with one outdoor tap, agree how the water is shared and paid for up front. To water less often:

• Self-watering containers. Self-watering baskets contain a water reservoir in the base to reduce the amount of watering needed.
• MulchA layer of material spread over the soil around plants to suppress weeds, retain moisture, and improve soil structure as it breaks down. Full definition →. A layer over the compost reduces evaporation, even in container plantings.
• Better compost, suitable plants and not overwatering. RHS lists these, adding organic matter and biochar as things to try before water-retaining granules, which may help but are a last resort.

Neighbours and shared space

• Keep shared access clear. Paths to bin stores, washing lines and the back gate should stay clear.
• Watch drainage. A container that drains onto a neighbour's window, a shared path or washing causes complaints.
• Secure anything at height. Fix pots and window boxes rather than balancing them on a rail, since they land on whatever is below.
• Keep escape routes clear. Do not let containers block a fire escape or stairwell.
• Manage mess and rats. A badly kept compost heap or overflowing water butt puts neighbours against a project and can draw rats into a shared back court: see keeping rats out of your compost heap and composting in a flat for flat-friendly options.

Bring compost up the stair in smaller bags, or split a larger order with neighbours who are growing in containers, so you share the cost and the carrying.
