How Long Does It Take to Build a Garden Room?
20th May 2025
When you’re investing in a garden room, one of the first things you’ll want to know is:
“How long will it take from signing off to moving in?”
At SmartSpaces, we pride ourselves on delivering stunning, fully functional garden rooms with minimal disruption and maximum efficiency. Whether you’re building a home office, gym, entertainment room, or self-contained annex, we’ve refined our process to ensure every stage is handled professionally and quickly.
Lead Time – When Can We Start?
Once you approve your final design, we’ll schedule your build within 6 – 10 weeks. This lead time allows us to:
- Finalise architectural drawings and specifications
- Procure made-to-measure materials and components
- Schedule experienced installers and specialist trades
- Manage any planning or compliance requirements
We communicate transparently from day one, giving you realistic timeframes and keeping you updated as your build date approaches.
Planning Permission – Do You Need It?
In most cases, garden rooms fall under Permitted Development and don’t require planning permission. However, there are a few exceptions:
You’ll likely need permission if:
- You’re building an annex with kitchen or bathroom
- Your room will be over 2.5m high and within 2m of a boundary
- You live in a conservation area or listed building
- The room is to be used as a permanent dwelling
The good news is our team will guide you through the process. If planning permission is required, we’ll help prepare and submit all the relevant documents, and handle communication with local planning departments.

On-Site Installation – Fast, Efficient & Professional
We’ve refined our construction method to make on-site builds as quick and smooth as possible.
Installation time: 5-10 working days
This includes:
- Groundworks and concrete base
- Structural framework and full insulation
- Doors, windows, and roofing
- Internal plastering and decoration
- Second fix electrics and lighting
- Final clean, handover, and snag check
Some typical examples include:
- A 5m x 3m garden room build would take around one week to complete including plastered finish and second fix electrics
- An 8m x 3.5m garden room build would take around two weeks to complete including plastered finish and second fix electrics
Larger or more complex structures (e.g. annexes with plumbing) may take longer, typically 4 – 6 weeks, especially when service trenches and fit-outs are included. We keep disruption to a minimum, most clients are surprised at how quickly their garden room becomes a liveable, high-end space.
Customisation & Optional Extras
Your garden room should work exactly how you need it to. That’s why we offer a wide range of optional features, many of which can be installed during your core build:
- Decking and outdoor seating areas
- Additional lighting or electrical points
- Partition walls and storage zones
- Climate control: underfloor heating, air conditioning, panel heaters
- Bespoke cladding, doors, and finishes
These upgrades won’t significantly delay your project and can be integrated seamlessly into the build.
