Question 1

Which greenhouse base type suits Brockenhurst's sandy soil best?

Accepted Answer

Brockenhurst's sandy podzol drains superbly, which is ideal for greenhouse growing but tricky for foundations. For most domestic greenhouses up to 8x10ft, paving slabs on a compacted sub-base are our recommended choice — they provide excellent drainage between joints while maintaining a perfectly level surface. Larger or heavier greenhouses benefit from poured concrete with integral drainage channels. If your garden has significant tree roots, ground screws bypass the problem entirely by sitting above root level. We assess your specific SO42 plot and recommend the most cost-effective, long-lasting solution.

Question 2

How do you ensure a greenhouse base stays level on loose sandy ground?

Accepted Answer

Sandy podzol soils settle unevenly unless properly compacted, and even a small amount of movement can crack greenhouse glass. We excavate to stable depth, lay a compacted type-1 sub-base in layers, and use laser levelling to achieve millimetre precision across the finished surface. For larger greenhouses, we may reinforce poured concrete with steel mesh to distribute loads evenly. This engineered approach is why we offer a 10-year guarantee — even on Brockenhurst's notoriously loose ground. The result is a base that keeps your greenhouse frame square and your glass intact.

Question 3

Can you install a greenhouse base near protected trees in Brockenhurst?

Accepted Answer

Absolutely. Many Brockenhurst gardens are surrounded by ancient oaks and beeches protected by Tree Preservation Orders. We frequently install greenhouse bases in woodland settings across the SO42 area. Ground screws are our go-to option near trees — they require no excavation, so root systems remain completely undisturbed. Alternatively, raised paving slab bases with minimal digging can work well outside the root protection zone. We assess the canopy and root spread before recommending a solution that protects the trees while giving your greenhouse a rock-solid foundation.

Question 4

What drainage does a greenhouse base need in Brockenhurst?

Accepted Answer

Brockenhurst's sandy podzol provides excellent natural drainage, so extensive artificial drainage systems are rarely needed. For paving slab bases, water drains naturally through the joints between slabs. For poured concrete, we incorporate a slight fall and perimeter drainage channels to direct water away from the greenhouse footprint. In lower-lying areas near streams — particularly between Boldre and Pilley — we may add French drains or a gravel soakaway to manage occasional winter waterlogging. Every base is assessed individually for your specific plot conditions.

Question 5

How much does a greenhouse base cost in Brockenhurst?

Accepted Answer

Greenhouse base prices in Brockenhurst start from £510 for a 9x5 paving slab base, £595 for an 8x6 poured concrete base, and £1,650 for an 8x6 ground screw base with timber frame. The final price depends on your greenhouse dimensions, ground conditions, and access. Properties with tree root complications or steep gradients may cost slightly more due to additional preparation. Your fixed-price quote includes all materials, labour, drainage preparation, and waste removal — no hidden extras. We can usually quote the same day from photos and measurements.

Question 6

Do I need planning permission for a greenhouse in Brockenhurst?

Accepted Answer

Brockenhurst falls within the New Forest National Park, which has stricter planning rules than standard local authority areas. Most domestic greenhouses qualify as permitted development, but National Park restrictions mean you may need permission if your greenhouse exceeds certain size limits, is positioned to the side of your house, or would push total outbuilding coverage beyond 50% of your garden area. Outbuildings more than 20m from the dwelling must not exceed 10 sqm. We strongly recommend contacting the New Forest National Park Authority on 01590 646615 before ordering your greenhouse.

Question 7

Which way should I orient my greenhouse in Brockenhurst?

Accepted Answer

For year-round growing in Brockenhurst, position your greenhouse with the ridge running east-west. This orientation maximises winter sun exposure, which is critical for extending the growing season. However, Brockenhurst's ancient woodland creates unique shading challenges — tall oaks and beeches to the south can cast shadows from October through March. During your site assessment, we consider tree canopy height, distance, and seasonal shadow patterns to recommend the best position. Sometimes a north-south orientation works better if large trees block southern light. We help you find the optimal spot.

Question 8

How does frost risk affect greenhouse growing in Brockenhurst?

Accepted Answer

The New Forest's inland clearings and valleys are prone to radiation frosts, particularly around Sway, Setley, and Dilton where cold air pools on still winter nights. Forest clearings can be several degrees colder than sheltered village centres. A properly installed, level base is essential for maintaining good seal contact between the greenhouse frame and the ground, preventing cold draughts that can damage tender plants. We ensure your base is perfectly level so doors and vents close tightly, and we can advise on positioning away from known frost pockets on your property.

Question 9

Can you install a greenhouse base on sloping forest ground?

Accepted Answer

Yes, sloping gardens are common across Brockenhurst, particularly in Sway, Boldre, and around Balmer Lawn. A greenhouse must sit on a perfectly level base regardless of the gradient. We achieve this by either cutting and filling on moderate slopes, or using a raised sub-base with retaining edges on steeper ground. Ground screws with a timber frame are excellent for slopes as they can be adjusted to create a level platform without major earthworks. We assess the gradient during your quote and recommend the most practical, cost-effective approach for your specific garden.

Question 10

What size greenhouse base do you install?

Accepted Answer

We install greenhouse bases of all sizes across Brockenhurst — from compact 6x4ft lean-to bases against cottage walls in Sway to large 12x8ft or even 20x10ft bases for serious growers near Rhinefield and Boldre. We match the base precisely to your greenhouse manufacturer's specifications, including any required overhang or bolt-down allowances. Every base is built to the exact footprint your greenhouse needs for a perfect fit. Share your greenhouse model and dimensions, and we'll provide an accurate, fixed-price quote.

Question 11

Do you install bases for lean-to greenhouses in Brockenhurst?

Accepted Answer

Absolutely. Lean-to greenhouses are popular in Brockenhurst where wall-mounted structures can benefit from the thermal mass of a south-facing house wall. We install slab and concrete bases right up to the building wall, ensuring the surface is perfectly level and flush with the existing wall line. We take care not to bridge the damp-proof course and ensure proper drainage falls away from the house. Lean-to bases are particularly effective against sheltered walls in the village centre where winter temperatures are milder than exposed forest clearings.

Question 12

How long does greenhouse base installation take in Brockenhurst?

Accepted Answer

Most greenhouse bases in Brockenhurst are completed within a single day. A paving slab base typically takes 4-6 hours, while poured concrete requires one day for installation plus 24-48 hours of curing before your greenhouse can be placed. Ground screw bases are often finished in half a day — the fastest option and ideal for forest gardens where minimising disruption matters. Complex sites with tree root considerations or restricted lane access may take slightly longer. We confirm the exact timeline in your quote so you can coordinate with your greenhouse supplier.

Question 13

Where can I buy a greenhouse near Brockenhurst?

Accepted Answer

Setley Ridge Garden Centre on Lymington Road is the most local option for growing advice and supplies. Fairweather's Garden Centre in nearby Beaulieu offers specialist plant knowledge for greenhouse growers. For the greenhouse structures themselves, Redcliffe Garden Centre in Bashley stocks garden buildings, and many Brockenhurst residents source greenhouses from specialist manufacturers who deliver across Hampshire. Order your greenhouse, then contact us for the base — we coordinate timing so your level, drainage-ready foundation is waiting when the greenhouse arrives.

Question 14

What guarantee do you provide on greenhouse bases?

Accepted Answer

We provide a full 10-year guarantee on all materials and labour for every greenhouse base we install in Brockenhurst. This covers structural integrity, levelling accuracy, and all materials including concrete, paving, reinforcement, and ground screws. Our guarantee specifically protects against the differential settlement common on sandy podzol soils — if your base moves, we put it right. We engineer every greenhouse base for the specific Forest conditions at your property, from sandy ground in Sway to tree-root zones in Rhinefield. The Phillips family has been in groundworks since 1970, and our guarantee reflects that confidence.

Question 15
