8×13 Wooden Greenhouse — NORDIC-L from £1,699
By the Waldenhaus founder team · Last updated: May 2026
Searching for 8×12? NORDIC-L is 8×13 ft — the closest size in our range. The extra foot at the back wall accommodates a workbench corner without sacrificing growing depth.
8×13 ft is the size for serious year-round growers. Enough space for two staging benches plus a workbench, indeterminate tomatoes climbing to the eaves without trimming, and full vine crops (cucumbers, melons) without cannibalizing seedling space. The footprint of ~2.4 × 4 m fits established UK back gardens and allotments without dominating.
NORDIC-L from £1,699 in the NORDIC range is what most experienced gardeners upgrade to after their first wooden greenhouse. Same engineering as the entry-level 8×6 and the walk-in 8×20 — same Swedish pine from sustainably-managed forests frame, same 1.2 mm galvanised steel, same screw-fixed CrystalLight panels.
Who needs an 8×13 ft greenhouse?
The pre-sales profile in our customer reports:
The serious year-round grower. Brassicas in the cold months, tomatoes/peppers/cucumbers in the warm months, never out of the greenhouse for long. NORDIC-L gives you ~9.7 m² — enough to run multiple "zones" without the structure feeling cramped.
The "I outgrew NORDIC-M" upgrader. Five years ago you bought a NORDIC-M (or equivalent), and now you've expanded into vine crops, started seed-saving for the local allotment community, want a workbench corner. NORDIC-L is the natural step.
The Yorkshire / Lake District weather-aware grower. You're north of the Trent. Winter starts in October. You need warm-mass growing space that doesn't shut down in November. NORDIC-L's larger thermal volume holds overnight warmth better than smaller sizes (more m³, less surface-to-volume ratio).
The 8×12 / 12×8 searcher. UK manufacturers vary on dimensions. If you're looking for "8×12 ft" in a wooden greenhouse, NORDIC-L at 8×13 ft is the closest match — and the extra foot at the back wall makes a real difference for workbench space.

Frequently asked questions
Is NORDIC-L the same as 8×12 ft?
Closest match. NORDIC-L is 8×13 ft. The extra foot at the back wall accommodates a workbench corner — most "8×12" searchers find NORDIC-L the right answer with bonus space.
Can I grow indeterminate tomatoes to the eaves in NORDIC-L?
Yes — eaves at 1.85 m and apex at 2.25 m gives full clearance for 2 m+ cordon tomatoes. Combined with ground-bed planting (vs. pots), you can get 2.5 m of cane growth before trimming.
Is 9.7 m² enough for serious year-round growing?
For most UK households yes — multiple zones for seedlings, cane crops, ground-bed brassicas. For market-grower scale, consider NORDIC-XL or NORDIC-XXL.
Is NORDIC-L heavier to assemble than NORDIC-M?
Same panel weights — just more of them. Two extra hours of glazing time vs NORDIC-M. Frame timber count goes up by ~30%.
Can I fit a wheelbarrow inside NORDIC-L?
Yes — 0.7 m central path is wide enough for a standard 0.6 m wheelbarrow + still pass benches.
Do I need a concrete base for NORDIC-L?
No — Heavy-duty Ground Anchors hold the frame against UK winter storms. Concrete is fine if you want permanence; anchors are better for allotment / future flexibility.
Should I buy NORDIC-L or NORDIC-XL?
NORDIC-L (8×13) is bench-led growing with a ground bed. NORDIC-XL (8×16) gives you serious central ground beds (1.2 m wide) for vine crops to the eaves. £100 difference. Choose by growing style, not just budget.
