 Cost of a extension

When deciding to undertake a extension its worth wile to have a think about what type of project your undertaking also what type of builder you would like to employ to complete the works.

Below specifies the different levels of jobs also provides square meter guides in order to help you get a ball park figure for your project.

Low-cost extension – low cost extensions can typically range from £1200m2-£1600m2.  Although low cost extensions can be a good option for some home owners; we typically don’t undertake these as they do not coincide with our values and company culture. We demand excellence.

Mid-range extension –  a mid-range extension can cost anywhere from £1600m2-£2200m2. Usually a mid range extension would be something like a simple rear kitchen extension or a side extension. when pricing a mi-range extension tjd would usually more towards the mid to high end of the price range.

We would be at this part of the price range as it allows us to deliver the project in a way which best accommodates our clients bespoke needs, this also allows us to use the best quality labour and materials on the project, ensuring we can deliver it to the highest possible standard; something we take extremely serious. We also project manage our builds to ensure trades/materials are on site when required and give clients a accurate update of progress on a weekly basis.

Premium range extensions –  premium range extension can cost anywhere from £2200m2-£4000m2 plus. In this range the design would typically be more bespoke along with higher end materials specified to be used. A example of this would be using stone as apposed to block or brick work.

Tjd joinery and building solutions excel at these type of builds. Our eye for details and meticulous planning ensures no stone is unturned in our drive to achieve the best possible outcome. We relish on the unique technical challenges these projects bring and will ensure we solve them the best possible way.

ADDITIONAL COSTS WHEN PLANNING A EXTENSION

We have listed some of the main costs involved in planning a extension there can be a few more but these are the main ones.

Architecture fees – The architect will work together with the builder and yourself to bring your ideas to life, they will draw the initial design also spec which materials would be preferably used.

Good drawings are paramount to a successful building project and will solve many problems before they arise, this will help bring the project in on time and on budget. We have many great architects we have worked with over the years so feel free to ask for our recommendations.  The cost of this will vary dependent on how detailed your drawings are also the architect you enrol to your project.

Planning permission – planning permission is required on most extensions with the exception. You will be required to submit a planning application and pay the required fees. Your architect or local authority will make you aware of these fees.

Building control fees – building control fees are usually around £200-£600 dependent on your project and control officer.

When planning you can choose to either use a private building control company or use your local authority’s direct.

Although private building control is slightly more in cost; We prefer to use them as we believe they are a lot faster, more efficient and easier to deal with. This can be a important factor when working to tight time scales.  This is not in anyway saying the local authority’s are no good its just our personal preference.

Factors which can change the cost

• Demolition of old structures i.e. garage or conservatory
• Additional steel work and knockthroughs
• Changes in the groundworks i.e deeper footings required
• Architects specifications
• Trees
• Fixtures and fittings
• Size/shape/height of the proposed extension
• Site constraints
• Windows and doors i.e bi-fold doors or rooflights
• Additional systems i.e underfloor heating system
• Change in scope
