Covering Tonypandy
We cover Tonypandy and the postcode districts CF39, CF40, CF41, CF43. We also work in nearby Rhondda (3 miles), Pontypridd (5 miles), Aberdare (6 miles), Maesteg (9 miles).
Just over the South Glamorgan border, Cowbridge is about 11 miles away. Welsh housing ranges from stone terraces in the valleys to render-and-slate houses and modern estates, and the Welsh planning rules differ from England's in several places.
What is included
- Window and rooflight placement to avoid screen glare
- Layout for desk, storage and video calls
- Data cabling and plenty of sockets
- Sound insulation to the adjoining rooms
- Heating or cooling sized for the room
North-facing glass and rooflights give steadier light for screen work. Where the office faces south, we use deeper reveals or external shading to keep glare and heat down.

Will the council need to approve it?
In Wales a single-storey rear extension can usually project up to 4 m beyond the rear wall without a planning application, if it is no more than 4 m high, keeps eaves to 3 m and overall height to 4 m within 2 m of a boundary, and covers no more than half the land around the original house. Wales has no larger home extension prior approval scheme.
Homes in conservation areas, national parks, National Landscapes (AONBs) and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Common questions in Tonypandy
Who do I contract with for a home office extension in Tonypandy?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Tonypandy, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Tonypandy?
Yes. We cover Tonypandy and the surrounding parts of Mid Glamorgan. Site visits are free and there is no obligation.
Is an attached office better than a garden office?
An attached office shares the house heating and broadband, adds floor area to the home, and needs no garden path in the rain. A garden building can be cheaper and quicker but is a separate structure.
Can I claim the cost against tax?
Building work on your home is not normally an allowable business expense, and claiming it can have capital gains tax effects. Speak to an accountant before assuming any tax relief.
