We recommend a concrete slab of at least 100mm thickness for most conservatories. However, ground conditions and larger structures often require greater depth. Our experienced team assesses your specific site to determine the optimal foundation depth based on soil conditions and your conservatory's design requirements.
Most conservatories don't require planning permission if they meet height, size, and placement limits. Rules are stricter in conservation areas or for listed properties though. We recommend checking with your local council before starting work to ensure full compliance with regulations.
We can typically install conservatory floor slabs within 1-2 days, depending on base size and weather conditions. Total project time may vary with ground conditions and curing requirements. Our efficient team works systematically to minimise disruption while ensuring quality results throughout the installation process.
Concrete bases provide long-term stability and durability that outperforms timber or paving alternatives. While modern steel bases offer quicker installation, they don't match concrete's longevity where heavy use or permanent structures are required. We believe concrete offers the best value long-term.
Absolutely! We regularly build stable concrete bases on sloping or uneven ground using stepped foundations, retaining walls, or cut-and-fill methods. Our problem-solving experience means we tackle challenging sites others avoid. Solutions depend on thorough site assessment, which we provide free of charge.
The cost of a conservatory concrete base depends on various factors. Size plays the key role here – a compact conservatory foundation typically costs less than an expansive sunroom base. Ground conditions, site accessibility, and slab thickness requirements all affect your final investment.
We consider essential site preparation too. This often involves excavation and ground levelling work. Some homes require extra groundwork when dealing with sloped terrain or properties that are tricky to reach.
