Recent extensions we’ve completed:
Swift Garden Room Extensions use many of the same processes and materials that we’ve successfully developed over ten years designing and installing our Swift Garden Rooms – “detached” extensions.
This major extension (below) to a detached bungalow provided an additional 80 square meters of luxurious living and sleeping accommodation. The white-render and cedar-clad finish produce a completely new and refreshing appearance to a 1970’s property.
Here are some of the main features:
- SIP panel construction
- EPDM roofing
- Large triple glazed roof lantern
- Bifold doors in grey
The extension on the right was completed in approximately 2 weeks. It was carefully designed to complement the garden room that Swift had built the previous year.
Originally a conservatory was planned, but this far-superior structure provides a beautiful room that can be used the whole year round. It doesn’t matter whether it is freezing, or sunny outside… or both!
This room features:
- Large, plain roof-light in grey to match the doors and windows
- External cedar cladding with pillars between the full height windows and door
- Opening windows for ventilation
Planning permission was gained for this appealingly modern structure that sits so well against a more traditional house. It is used every day and has transformed the enjoyment of this lovely home.
It was one of our fastest installations, taking just 7 working days – including the flooring being laid and the internal walls painted white!
How are they built?

Design Process
If your project demands complex alterations to the existing fabric of the house, then this will probably not fall within our remit. However, we may be able to work with other parties to provide the main fabric of your new space. Other contractors can concentrate upon items such as major preparations, knock-throughs kitchen re-fits, etc.
Planning Permission
Some home extensions can be undertaken without full planning approval – this is the case if they fall within Permitted Development Rights (PDR). You can find out more by visiting the Official Planning Portal (just click here).
There are some important PDR conditions, especially concerning the dimensions and the external materials. Once again, we are here to guide you and advise you. We are able to provide a full planning consultation service and so the process can be simplified for you. Where a planning application is made on your behalf we usually expect a decision within a couple of months and, when successful, we can immediately start work on creating your new space.
What to do now?
Perhaps we can add some inspiration that will excite you and make your investment all the more special. Call us on 01625 875588 or send us an email via our contact page.
We look forward to hearing from you.
SIP’s
By using these panels we can have most of the work carried out in a dedicated factory where nothing will get in the way of the perfectly designed and aligned panels being prepared for your new room. When they are delivered to site they can be erected in impressively short time-scales. Sometimes a compact room can be completed in a single day.
Footings and foundations
These can include the following:
- Concrete footings and insulated concrete floor
- Reinforced concrete raft
- Concrete pads supporting a ring beam with integrated SIP panels
- Building Regulation approved Helical Screw Piles
Roofs
External Finish
- Cedar cladding
- Alternative timber finishes
- Render (in various colours)
- Coloured fascia panels
- Powder coated aluminium or steel
- Composite painted wood-effect cladding
- Porcelain Tiles
- Green “living” walls
As you can tell… the choices are almost endless.
