Services
Garden Verandas
Our garden verandas create seamless transitions between indoor and outdoor spaces. These weatherproof structures feature aluminium frames and optional glass or polycarbonate roofs, providing durable solutions for dining, relaxation, or entertaining. Customisable with lighting, heating, and sliding walls, they extend outdoor living seasons while maintaining aesthetic appeal.
Glass Sunrooms
Glass sunrooms offer 360-degree protection with maximum natural light transmission. These insulated spaces feature thermally efficient frames and roofs, allowing year-round use. Optional extras include underfloor heating, smart lighting systems, and bespoke finishes, making them ideal for lounging, dining, or home offices in British weather conditions.
Free-standing Garden Rooms
Free-standing garden rooms provide versatile spaces for recreation, work, or storage. Constructed with durable aluminium and glass materials, these structures require minimal maintenance. Available with flat or pitched roofs, they can be customised with electrical installations, insulation, and access points to suit various garden layouts and purposes.
3D Design Service
Our 3D design service allows customers to visualise their outdoor spaces before installation. Using digital tools, we create accurate representations of proposed structures within existing garden environments. This service ensures precise measurements, material selections, and layout optimisation to meet individual requirements and planning considerations.
Nationwide Installations
Professional installation services operate across mainland UK, excluding Scotland. Our experienced teams handle groundwork preparation, structural assembly, and final inspections. The process includes site surveys, timeline coordination, and post-installation walkthroughs to guarantee customer satisfaction with every veranda and sunroom project.
Questions
What is the price range for a standard veranda?
Standard aluminium verandas start from £3,000-£4,000 with polycarbonate roofs, while glass versions range from £4,500-£8,000 depending on specifications.
Do I need planning permission for a garden room?
Most installations fall under permitted development rights, though exceptions apply for listed buildings, conservation areas, or structures exceeding 3m height.
What warranty options are available?
We offer a 10-year warranty on aluminium frames and 5-year coverage for glass components and electrical accessories with all installations.
Can I add heating and lighting later?
While optional extras can be retrofitted, we recommend including them in initial designs for seamless integration and reduced disruption.
How long does installation take?
Most verandas install within 1-3 days, while complex glass rooms may require additional time depending on size and custom features.
What maintenance is required?
Annual gutter cleaning and occasional washing with mild soapy water maintains appearance, with aluminium frames and glass requiring minimal ongoing care.
