15 Questions to Ask a Greenhouse Supplier Before Ordering

Check 01 · first review point

Match model and intended use

Start by asking which specific greenhouse the supplier recommends for your purpose, and why. Are you raising seedlings, growing vegetables or creating a sheltered workspace? Your use affects the suitable size, door arrangement and interior layout. Ask for the selected version to be named clearly in the quotation so assumptions are not lost between advice and ordering.

Also ask whether measurements refer to outside edges, usable floor area or the highest point. Planning needs more than internal room: allow space around doors, paths and access for plant care. A sketch of your garden helps put the answer in context. Check that intended shelves, benches or growing areas will fit the chosen layout realistically.

Keep the supplier’s recommendation alongside your own requirements. This shows whether the proposed size genuinely suits your growing goals, circulation space and available paths. For variants, ask for differences to be explained using the relevant product documentation, not only verbally.

Put the key measurements and site features into a short note for the consultation. It will make it easier to compare the supplier’s details with your actual installation situation later.

• Which model name and equipment version, including every selected option, will appear in the order summary?
• Which internal dimensions matter for my crops and working routes, and how are they documented?

For planning a freestanding garden structure, consider a standard Classic greenhouse with a model configuration that can be checked clearly.

Discuss site, wall and foundation

The second question is: what must my site provide? Describe orientation, soil, slope, nearby trees and garden access. The supplier can explain the preparatory work specified in its documents. You must still measure the area carefully and arrange suitable professional ground preparation where your situation requires it.

For a lean-to greenhouse, ask specifically about the existing wall. Relevant considerations include a sound base, connection details, eaves, downpipes and accessible assembly areas. Do not accept a general statement of suitability: clarify which measurements and building conditions need checking on site. Independent professional advice can be useful if you are unsure.

Document the intended position with photos from several directions and a simple sketch. This makes it easier to discuss obstructions, connection points and work areas. Also check that doors, windows and maintenance areas at the building will remain accessible.

Make sure the product documents relate to the version actually selected. This link avoids misunderstandings, especially where images show optional elements or different opening arrangements.

• What information about soil, slope and foundation does the supplier need before assessing the appropriate version?
• Which existing features of the house wall could affect planning, access or the greenhouse connection?

For an extension against a façade, look closely at a regular lean-to greenhouse and its site-specific requirements.

Check materials and components

Ask which components make up the frame, glazing, doors, roof vents and fixings in the offered version. Material names alone are not enough: they must relate to your chosen configuration. Ask which components are standard and which can be selected. This helps prevent confusing product images with a different equipment level.

Ask about care instructions for visible surfaces and transparent elements too. Find out which cleaning methods or products are suitable according to the manual and which are not recommended. If spare parts are needed, ask how individual components are identified. A clear parts list makes future enquiries more precise.

Always compare material information within the same configuration. Images may show accessories or variants that are not automatically part of your selection. Written confirmation of frame, glazing, opening elements and fixings helps you assess the offered version accurately.

Check the packing list against the order summary. A simple mark beside each reviewed item helps you document differences and formulate precise follow-up questions.

• Which components and finishes belong exactly to the offered version, and where are they listed in writing?
• Which care guidance applies to the frame, glazing, fittings and moving elements in everyday use?

Anyone comparing a freestanding solution can assess a freestanding Classic greenhouse through its documented components.

Separate package and delivery

Ask the greenhouse supplier how the package is divided and which parts should be checked on arrival. A detailed packing list is useful, especially when components arrive in separate packs. Also confirm what information is needed before delivery so vehicle access, unloading space and helpers can be prepared realistically.

It is important to distinguish delivery of goods from additional services. Ask expressly whether carrying items to the build location, assembly or packaging disposal forms part of your selection, or must be arranged separately. Do not assume access is possible on your property. Assess and report narrow passages, steps, gates and long carrying distances in advance.

Set aside a protected, accessible place where packages can remain organised until assembly. Photograph damaged packaging or missing items promptly and compare your observations with the order documentation.

Do not schedule assembly under time pressure. A prepared work area, sorted packages and a previously read sequence make it easier to complete each step carefully and in the intended order.

• Which packages, documents and checks should I review against the order records when delivery arrives?
• What requirements apply to access, unloading space and moving components to the intended assembly site?

When planning a façade extension, it helps to review a wall-attached regular lean-to greenhouse with its coordinated package contents.

Prepare realistically for assembly

A key question concerns assembly: which stages does the installation manual describe, which tools are required and how many people should you realistically plan for? Request access to the relevant documents before ordering. Read the sections on foundations, component sequence and safety precautions carefully. This helps you decide early whether to assemble it yourself.

Ask which checks are required after individual assembly stages. Alignment, secure connections and correctly installed components deserve particular attention. If you are considering third-party installation, give the installer the model documents in good time. The supplier should be able to explain which preparatory work is your responsibility and which instructions apply to the configuration.

Read assembly documents not only for individual steps but also for their sequence. Prepare tools, work space and any required aids beforehand. This gives you a better idea of which tasks you can undertake yourself and where assistance may be useful.

Create an accessory priority list covering essential function, desired comfort and later additions. It will show which decisions matter for assembly and which can remain open initially.

• Which tools, helpers and preparatory tasks does the manual expressly specify for the selected version?
• Which assembly stages should I agree with an appointed installer before work begins?

For an independent garden project, examine the assembly documents for the Classic greenhouse for the garden especially carefully.

Plan climate, ventilation and accessories

Ask not only which accessories are available, but what purpose each serves in your use. Ventilation, shading, shelving and watering are chosen more effectively when you describe crops, care time and sunlight. Request a clear distinction between basic equipment and additional options. This keeps the quotation readable and your budget understandable.

Discuss whether later additions are possible. Some are best assessed after assembly, while others should be planned early because they affect the structure or internal layout. Ask what information you need for that decision. Avoid blanket expectations about temperature or harvests: results always depend on site, weather, care and selected equipment.

When planning accessories, consider future care routes and access to plants. A well-organised interior accounts not only for growing space, but also ventilation, room to move and the placement of items used or cleaned regularly.

Keep photographs, correspondence and product documents with the order summary. This record makes it easier to identify your configuration if a question arises during assembly or later.

• Which accessories specifically support my planned crops, and which are already included in the selected package?
• Which additions should be decided before assembly, and which may be considered later after discussion?

On a sunny side of the house, a regular lean-to greenhouse beside the house can be planned with the accessories required.

Documents, contacts and spare parts

Before buying, ask which product documents you will receive and in what format. They may include assembly guidance, care information, parts lists and usage notes. Ask how to reach the right contact if a specific question arises during preparation or assembly. A clear communication route is often more useful than a broad service promise.

Also ask about the procedure for missing, damaged or later-required parts. What matters is the information needed for identification, such as order details, photographs or a parts-list designation. Keep the order confirmation and documents organised. This makes identification easier and prevents an enquiry relying on an unclear model description.

Set up one storage place for the quotation, order confirmation, manual and photographs. Record the model name and chosen options there. For later enquiries, you can then give the supplier complete information without unnecessary delay.

• Which manuals, care information and parts lists will I receive in a clear form for my configuration?
• What details should I keep for a later parts enquiry so the affected component can be identified clearly?

For documenting a freestanding model, choose a Classic greenhouse as a standard model with clearly assignable documents.

Read commercial guarantees and written terms

Finally, ask which written terms and any commercial guarantee apply to your order and where you can read them before purchase. Ask how to report a problem and what information is required. Advice during a consultation can help, but does not replace the applicable documents or any applicable rights under New Zealand consumer law. Review the stated scope, conditions, exclusions and procedures carefully.

If you have questions about insurance, boundary setbacks or possible site requirements, contact the relevant council, your insurer or qualified professionals. A greenhouse supplier can provide product information but cannot replace a binding assessment of your individual circumstances. Keep answers and documents together so you can later understand your decision.

Read written terms in connection with your specific order and keep the associated documents. If terms or procedures remain unclear, ask for an explanation. Separate product information from questions requiring individual professional assessment.

• Review the written terms and any commercial guarantee for your order, including the reporting process, before completing the purchase.
• Where can I find the written terms for my order, what reporting steps does the supplier specify, and which local questions about site, insurance or building requirements must I clarify independently?

When comparing an extension, fully review the documents for a large lean-to greenhouse for the house wall before committing.
