We’ve been exploring the work of Pecasa Garden Rooms, a specialist garden room and annexe company working across North London, Hertfordshire, and Buckinghamshire. As the project images show, their buildings lean towards a contemporary aesthetic, with clean lines that can be tailored around the intended use of the space, the setting of the garden, and individual tastes.
Pecasa design and build bespoke garden rooms and garden annexes, creating spaces that range from home offices and gyms through to self-contained living accommodation with kitchens and bathrooms. Much of the structural work is carried out off-site in their local workshops, which helps keep the on-site phase relatively short and controlled. This approach reduces disruption at home, with typical installations completed in around two weeks or less, depending on the specification and site conditions.
Design-Led Process With An Online Configurator
For many clients, the process begins with Pecasa’s online design configurator. This allows you to explore both mono-pitched and dual-pitched designs, experiment with door and window layouts, and see a guide price update as you refine your choices. From there, projects move into a design consultation with the Pecasa team, where layouts, finishes, and technical details are developed further to suit both the intended use of the building and the constraints of the site.
The configurator also provides a clear overview of the range of exterior finishes Pecasa offer. Clients can choose from a wide selection of cladding styles, including durable timber options, maintenance-free composite materials, and more characterful finishes such as stone. Choices around cladding orientation, colour, aluminium doors, window styles, and contemporary detailing make it easier to tailor the appearance of the building to suit both personal taste and budget, while keeping the overall design cohesive.
SIPs Construction For Shorter Build Times
Structurally, Pecasa build their garden rooms using Structural Insulated Panels (SIPs), which form a rigid, well-insulated core. Because these panels are pre-manufactured off-site, the main structure can be erected quickly and made weather-tight in a short timeframe. The result is a multi-layer building designed for comfortable, year-round use, with thermal performance that allows the space to be used much like a room in the main house.
High-Quality Interior Finish And Services
Internally, Pecasa finish their garden rooms to a high standard, with plastered and decorated walls and ceilings that give the space the feel of a room in a new build house. Flooring is chosen to suit the intended use of the room, allowing clients to balance practicality, comfort, and appearance.
Electrical layouts are developed as part of the design process, with Pecasa working alongside clients to plan lighting, power, and data points around how the space will be used. Heating and cooling systems can also be incorporated into the specification, helping to ensure the building remains comfortable throughout the year.
We also note that Pecasa Garden Rooms offer a finance option for those looking to spread the cost of their project.
