The Lounge Luxury SIP Garden Room
A premium installed SIP garden room designed for customers who want a comfortable, year-round space for relaxing, working, entertaining or unwinding at home.
A Refined Garden Room for Everyday Living
The Lounge is the main lifestyle design in our signature range. It has a wider, more open front elevation than The Studio, with a large central aluminium glazed opening and solid wall sections either side for furniture, privacy and structural practicality.
It is designed for customers who want a luxury garden room that feels calm, usable and permanent — not a lightweight summerhouse or a basic timber outbuilding.
The Lounge Sizes and Starting Prices
Choose from three standard sizes. Each option is based on a SIP floor, wall and roof structure, EPDM roof covering, external cladding, standard aluminium glazing package and installation of the garden room structure.
Starting prices are for installation onto a suitable prepared level base. Final price depends on size, finish, access, glazing choices and any additional works required.

Who The Lounge Is Best For
Garden Lounge
A calm space for sitting, reading, relaxing or creating a separate retreat away from the main house.
Home Office
A premium working space with better comfort and appearance than a basic garden office pod.
Studio or Creative Space
A year-round room for creative work, treatment space, content creation or a quiet professional setting.
Entertaining Space
A practical garden room for hosting, evening use, a small bar area or family overflow space.
Gym or Wellness Room
A stronger, insulated shell suitable for a more comfortable private gym or wellness space.
Premium Multi-Use Room
A flexible design for customers who want one garden room that can serve more than one purpose.
Exterior Finish Options
The Lounge is available in our two standard exterior finish routes, with bespoke finishes available by quotation.
Architectural Anthracite
A sharp, darker finish for customers who want a clean contemporary look with premium glazing, slim detailing and a more architectural feel.
Natural Timber
A softer exterior finish for gardens where a warmer, more natural luxury look is preferred.
Designed for Real UK Garden Positions
Many customers need their garden room close to a boundary, so The Lounge can be designed around a 2.5m overall-height version where required. A taller version up to 3.0m can be offered where the site position and planning rules allow.
2.5m PD-Friendly Version
The usual route for many domestic gardens where the room may need to sit close to a boundary.
Up to 3.0m Tall Version
Available where the site allows, giving a more spacious internal feel and stronger proportions.

Why The Lounge Uses SIP Construction
Stronger Shell
The room starts with a structural insulated panel shell rather than being treated as a decorative outbuilding first.
Year-Round Usability
SIP construction gives The Lounge an insulated structure from the start, helping it feel more suitable for regular use throughout the year.
Wide Glazing, Practical Wall Space
The large central glazed opening brings in light, while solid wall sections either side give space for furniture, sockets, storage and internal finishes.
Built by SIP Panel Specialists
Luxury SIP Garden Rooms is supplied by Sips & Splines, a trading name of HFI Services Ltd. Based in Liverpool, we manufacture SIP garden room structures and install premium garden rooms for customers across the North West.
Our background is in SIP panel manufacture, insulation and practical site installation. That means The Lounge is built from the insulated structure outwards, with the exterior finish, glazing and detailing added to a strong shell.
