Waldenhaus Limited · England & Wales

Garden architecture for British weather.

Two greenhouse ranges, built around the same plain rule: the specification on the page must hold up in the garden.

01 · Why we exist

The accessible greenhouse market was built to a cost, not to a British winter.

For most British gardeners who spend between £600 and £2,000 on a greenhouse, the pattern repeats. The decision takes months. The assembly takes a weekend longer than advertised. The spring in the structure feels good. The October in it feels uncertain.

This is not the customer's failure. It is the category's. Frames twist at joints that were never designed for British wind loads. Glazing blows out because spring-clip systems corrode and let go. Warranty terms are published before the order, so the customer can read the limits before committing.

Waldenhaus exists to occupy the gap between heirloom glasshouses few can justify and mass-market structures that rarely feel ready for their second growing season.

02 · What we make

Two structures. One operating standard.

NORDIC and SteelRoot look different because the gardens are different. The engineering logic is shared: galvanised load points, screw-fixed glazing, published product terms and ground anchors included.

NORDIC From £1,049

Timber, but not decorative timber.

45 × 45 mm Swedish pine, 1.2 mm galvanised steel angle brackets at every node, 4 mm CrystalLight twin-wall polycarbonate and screw-fixed glazing from base to apex.

  • Five sizes · 8 × 6 ft to 8 × 20 ft
  • Cross-ventilation as standard — rear opening window opposite the door
  • Ground anchors included
See NORDIC
SteelRoot galvanised-steel arch greenhouse side profile
SteelRoot SteelRoot steel arch greenhouses

Galvanised. Arched. Quiet about it.

40 × 20 mm closed RHS galvanised steel with ZAM coating (zinc-aluminium-magnesium), 6 mm cellular polycarbonate and screw-fixed glazing for long, exposed plots.

  • Five lengths · 10 × 14 ft to 10 × 40 ft
  • Arch spacing designed for UK wind load
  • Ground anchors included
See SteelRoot
03 · How it holds together

The design language is quiet. The construction is not vague.

Every public claim has to land on a number, a material, a build step or a service promise. That is the difference between a nice-looking greenhouse page and a structure you can judge before it arrives.

05 · Principles

Five rules that shape the product pages.

  1. 01

    Specify, do not inflate.

    A 45 × 45 mm cross-section earns more trust than a vague timber adjective.

  2. 02

    Publish the conditions.

    Warranty terms belong before the order, not after the delivery.

  3. 03

    Include the anchor.

    A polycarbonate-glazed structure catches wind. The sensible fixing should be standard.

  4. 04

    Avoid claims we cannot prove.

    We say what we engineered, what the specification is, and what the published terms cover.

  5. 05

    Design for the second winter.

    A garden structure should still feel considered after the first season has passed.
