Local Planning & Regional Considerations
We understand the specific planning requirements and environmental factors across our service areas
Conservation Areas & Article 4
Many areas across Surrey, Sussex, Kent, and London have enhanced planning controls. We regularly secure approval in conservation areas, Article 4 direction zones, and within the South Downs National Park through expert applications and conservation officer engagement.
Coastal Exposure Expertise
Properties in West Sussex, East Sussex, Kent, and Dorset coastal locations require enhanced specifications. We use marine-grade materials, calculate wind loads for exposed positions, and design for salt air protectionβbacked by 50+ years coastal experience.
Lead Times by Region
Typical project timeline from consultation to completion is 4-6 months including design, planning, and installation. London and conservation area projects may require additional planning time. Modular extensions can be as little as 5-7 days on-site installation times depending on design.
Listed Buildings & Heritage
We work with Grade I, II, and II* listed properties across Kent, Hampshire, Surrey, and Sussex. Our designs respect heritage character while meeting modern thermal standardsβoften achieving Listed Building Consent where others have failed.
Green Belt & AONB
Experience with Green Belt applications across Surrey, Berkshire, and Essex, plus Areas of Outstanding Natural Beauty in Hampshire, Dorset, and Sussex. We understand the "very special circumstances" test and prepare robust planning cases.
Glass Performance & Temperature Control
New Generation Glass technology addresses the UK's variable climateβkeeping extensions warm in winter and preventing overheating in summer. Particularly important for south-facing installations and coastal properties with high solar gain.
Frequently Asked Questions About Our Service Areas
Yes. We regularly work in conservation areas across West Sussex, including within the South Downs National Park. Our Design Consultants understand local planning requirements and work closely with conservation officers to ensure compliance.
Recent conservation area projects include installations in Chichester, Arundel, Midhurst, and coastal conservation zones. We prepare detailed heritage statements and design extensions that respect local character while meeting modern standards.
From initial consultation to completion, typical projects take 4-6 months including design, planning approval, and installation. This timeline applies to most Surrey and Hampshire locations for standard orangery and conservatory projects.
Some structures may fall within permitted development rights and therefore not require planning permission which can vastly reduce the lead time and this can be discussed with your design consultant.
Conservation area or Green Belt projects may require additional planning time (8-12 weeks for approval). Modular extensions significantly reduce this timelineβinstalled in just 5-7 days after planning approval, making total project time as little as 8-12 weeks.
Yes. Coastal installations are one of our specialisms with 50+ years experience along the South Coast. Coastal properties require specific considerations for wind exposure, salt air corrosion, and marine environment conditions.
We use marine-grade aluminium, enhanced structural calculations for wind loads, and specialized sealing systems. Projects completed in exposed coastal locations from Selsey to Eastbourne, Bournemouth to Hastings, with outstanding long-term performance.
Yes. Many London boroughs have Article 4 directions that remove permitted development rights, requiring full planning applications. Our team is experienced in navigating London's complex planning requirements and securing approvals across all London boroughs.
We understand borough-specific policies, conservation area requirements, and limited access challenges common in London. Recent London projects include installations in Richmond, Kingston, Wandsworth, Bromley, and multiple other boroughs.
Yes, we cover Kent and Essex in their entirety for our regional services (conservatories, refurbishments, maintenance, and modular extensions). From Canterbury to Maidstone, Chelmsford to Colchester, and all coastal towns.
For national services (orangeries and frameless glass extensions), we work anywhere in Kent, Essex, or across the UK. Our Design Consultants travel throughout both counties for site visits and consultations.
Yes, planning requirements vary by local authority, not by county. Each council has different policies, processing times, and local plan requirements. However, we handle all planning submissions regardless of location as part of our service.
Our knowledge spans local authorities across West Sussex (Chichester, Horsham, Worthing, etc.), Surrey (Guildford, Waverley, etc.), Hampshire, Kent, and all our service counties. We tailor applications to each authority's specific requirements.
National Coverage (anywhere in UK): Bespoke orangeries, frameless glass extensions, Oak Buildings, and Annexes and Garden Rooms. Our design team works nationwide with local installation partners where needed.
Regional Coverage (South & South-East): Full range including conservatories, refurbishments, New Generation Glass upgrades, Groom Outside maintenance, and modular extensions across West Sussex, East Sussex, Kent, Essex, Hampshire, Surrey, Dorset, Berkshire, and Greater London.
Our structural warranty is up to 10 years, but the exact terms vary by product and by the installation partner who serves your area. Your Design Consultant will confirm the cover that applies to your project and provide it in writing before you order.
All our projects include insurance-backed guarantees for your protection. Terms are consistent within each product categoryβno postcode lottery on quality or protection.
