The greenhouse project process in Spain — scope to supplier offers
Spain combines Europe's lowest-cost commercial greenhouse format with sophisticated water and crop management. Almería's raspa y amagado houses use local structure, film and passive ventilation; higher-tech multi-span and glass projects appear where crop quality, labour efficiency or year-round contracts justify them. Water allocation, desalination and drain recovery are the decisive non-structure costs.
Direct answer
A commercial greenhouse project in Spain runs through six stages: define scope and season, set the local cost band, build the CAPEX estimate, run the readiness check, submit one written specification through a private RFQ, then compare landed offers on a like-for-like basis. Every brief is reviewed by a sourcing specialist before any supplier is approached — nothing is published and no supplier contacts you directly.
The six stages
1. Define the project scope
Fix the site location in Spain, the cropped area, the target crop and the production season. Locally, that usually means tomato, pepper, cucumber, courgette, aubergine, melon, berries, herbs and nursery crops for spanish and european retail.. Scope decides the technology level long before any supplier is involved.
2. Set the local cost band
Read the published Spain installed bands per m² and per hectare, and the operating cost that goes with each technology level. These are planning bands, never a quotation.
Open this step3. Build the CAPEX estimate
Run the country builder for your area, structure level and site condition. Site works and connections in Spain typically add the uplift described below, on top of the hardware band.
Open this step4. Check project readiness
Run the builder readiness check. It confirms whether the scope, water, power, budget and decision path are defined enough for suppliers to price the same thing, and names exactly what is still missing.
Open this step5. Submit one written specification
Submit a private project brief. A sourcing specialist reviews it, converts it into one written specification and approaches qualified suppliers manually. Supplier identities stay private and your contact details are never released before review.
Open this step6. Compare offers on one basis
Compare returned offers on a landed, like-for-like basis for Spain — the same structure, climate, irrigation and installation scope in every offer. That is the first number a lender or board will work with.
What decides the budget in Spain
Mediterranean — mild winters, hot dry summers and intense solar radiation, with water scarcity strongest in Almería, Murcia and the southeast.
Water allocation
Legal availability, salinity, desalinated-water tariff and reservoir volume determine both viable area and irrigation capital.
Local structure format
Almería's mature local construction supply chain keeps passive-house costs far below northern European glass references.
Heat and radiation
Shade, whitening, ventilation and insect net porosity determine summer crop conditions; mechanical cooling is uncommon at basic technology levels.
Drain recovery
Substrate projects add collection, disinfection and nutrient recirculation to reduce water and fertilizer discharge.
Labour and packing
Automation, grading and packhouse capacity are increasingly important where retail specifications and labour availability tighten.
Site works and exclusions
Add 12–25% for levelling, drainage, reservoirs, desalinated-water connection or treatment, roads and electrical service. Land, packhouse and cold storage are separate.
Financing routes
Spanish projects commonly combine bank lending or leasing with eligible regional, national or EU agricultural and water-efficiency programmes. SeedMatchGroup is not a lender; support is independent and supplier-backed scope is required.
Build your Spain estimate
For Spain, enter the production region, summer radiation, water allocation and EC, and whether the crop uses soil or recirculating substrate. The irrigation planner should test reservoir and drain-recovery requirements.

Planning bands only — not a quotation and not a SeedMatchGroup price. Committed pricing comes from qualified suppliers responding to one written specification, reviewed by a sourcing specialist before any supplier is approached.

Project process questions
How does a greenhouse project in Spain move from idea to supplier offers?
In six stages: define the scope and season, set the local cost band, build a CAPEX estimate, run the readiness check, submit one written specification through a private RFQ, and compare offers on a like-for-like landed basis. A sourcing specialist reviews the brief before any supplier is approached.
What budget should a project in Spain plan for?
At the published planning bands, a technical multi-span polyhouse costs roughly USD 60–140 per m² installed, which is about USD 600K – USD 1.4M for one hectare before site works and land. Add 12–25% for levelling, drainage, reservoirs, desalinated-water connection or treatment, roads and electrical service. Land, packhouse and cold storage are separate.
What usually delays a project in Spain?
Undefined water source and quality, an unconfirmed power connection, and a scope that changes after suppliers have quoted. The readiness check exists to surface those before the RFQ, not after.
Does SeedMatchGroup build or finance the project?
No. SeedMatchGroup is not an EPC contractor, engineering firm or lender. It runs a human-reviewed sourcing process: one written specification, qualified suppliers approached manually, and comparable offers returned to you. Spanish projects commonly combine bank lending or leasing with eligible regional, national or EU agricultural and water-efficiency programmes. SeedMatchGroup is not a lender; support is independent and supplier-backed scope is required.
What project size is worth this process?
SeedMatchGroup works on commercial agricultural projects from roughly USD 250,000 upwards. Smaller builds are better served by a local supplier directly.
