Professional Modular Spaces in Southend
For residents in Southend-on-Sea, space is often at a premium. Our P600 modular system allows homeowners to maximise their outdoor space without the disruption of a months-long construction project. Because our modules are manufactured in a controlled factory environment, we can deliver a completed building to your site in weeks rather than months. These are not sheds; they are high-performance garden rooms featuring plastered internal walls, double-glazed uPVC windows, and full thermal insulation.
Who It Suits and Typical Configurations
Our system is highly flexible, allowing you to combine modules to suit your specific garden layout and intended use. The P600 module measures approximately 13 m², and these can be joined side-by-side or even stacked for two-storey applications.
- Single Module (13 m²): Ideal for a quiet home office or a treatment room for a small business. Perfect for standard urban garden plots in areas like Prittlewell.
- Double Module (26 m²): A popular choice for a substantial garden gym or a teenagers' den, providing enough space for multiple zones.
- Four+ Modules (52 m²+): These configurations suit large residential plots, creating annexes or extensive hobby spaces that rival the footprint of a small bungalow.

What is Included as Standard
Every Adacon P600 building is delivered with a comprehensive internal specification as standard. This ensures you do not have to source multiple contractors to finish the interior. Included in the base price are:
- Fully insulated floor, walls, and roof for year-round comfort.
- Plastered and painted internal walls.
- Laminate flooring in a choice of finishes.
- LED lighting and pre-installed electrical sockets.
- Double-glazed uPVC windows and external doors.
- Exterior cladding in a variety of colours, selectable on a wall-by-wall basis.
We also offer optional upgrades such as WC and shower compartments, kitchenettes for self-contained use, air conditioning for climate control, and external decking to integrate the building into your garden landscaping.
Indicative Prices for Southend Residents
While every project is unique, most residential garden room projects in the Southend area fall within a price band of £15,000 to £35,000. This range typically covers single to double-module builds with standard configurations. The final cost is influenced by your choice of windows, the number of doors, and any internal upgrades like plumbing.

Delivery and Installation to Southend-on-Sea
Logistics are a key part of our service. Our modules are transported via the A127 or A13, reaching Southend from our main distribution points. We have experience delivering to a variety of site types across the borough, from wide-access plots in Shoeburyness to more constrained residential streets in central Southend. For most deliveries, we use a lorry-mounted crane (HIAB) to offload the modules directly onto your prepared base.
It is important to note that the customer is responsible for ensuring a level, prepared base is ready before delivery. You will also need to arrange for a qualified electrician to connect the building to your mains consumer unit and, if applicable, a plumber to connect drainage. For projects with restricted access—such as terraced houses with no rear access—a larger crane may be required to lift the modules over the roofline, which we can discuss during the quotation process.
Planning and Regulations
When installing modular buildings in Southend-on-Sea, you must consider local planning rules. Many garden rooms fall under Permitted Development, meaning they do not require full planning permission, provided they meet specific criteria regarding height and placement. However, rules can vary significantly depending on whether you live in a conservation area or a listed building. We always advise checking with the Southend-on-Sea City Council planning department before commencing work.
