Property Extensions in Worthing | What You Need to Know

Property extensions are a popular project among home and business owners alike. When you consider their benefits, it’s not hard to see why. However, as with all types of construction, there are some important details to know before you jump in. Whether undertaking extensions, property refurbishments, new builds or loft conversions in Worthing, we ensure every customer receives the best advice and knows what to expect. On this page our house builders provide some of the key information you need to know.


With many years’ experience designing, planning and building property extensions, we are in the perfect position to advise customers on every aspect of construction.


Planning Permission


For domestic property extensions, including some loft conversions, planning permission is often not necessary as long as work falls within permitted development rights. New structures must meet certain requirements, but our house builders are always happy to advise on these.


As a reputable company, Phase One Build always ensures relevant permissions are in place before beginning work in Worthing. If you have an industrial or listed building, or if it is in a conservation area, further restrictions may apply. In some cases, property refurbishments may also require prior approval.




One of the most important aspects to consider when planning property extensions is the overall cost. While they are often a cost-effective solution to upsizing, as well as adding value, you need set a budget at the beginning of the planning phase to ensure the project runs as smoothly as possible.


While many customers in Worthing and Chichester are aware of the obvious costs, such as materials and labour, additional costs can easily get overlooked. Our house builders help set realistic budgets, taking into account things like planning applications and architects as well as building regulation and structural engineering fees.


If budget restrictions are an issue, loft conversions and property refurbishments may be a suitable alternative. These can add space and function to your home or business, generally at a lower cost.




Just like project costs, it is vital to consider the schedule of work. Different factors can increase or decrease the scope of projects in Worthing and Sussex, for example if you plan on living in your house during construction.


If you have a set deadline for completion, you need to know if property extensions or other work can realistically be finished in that timeframe. No matter the construction project, it is important to plan for unexpected delays.


Your Boiler


Your boiler is an essential part of your home and you want to make sure it will effectively service additional spaces, whether that’s property extensions or loft conversions. If your boiler can’t cope with the extra structure, you will experience heating problems that impact the comfort and functionality of your home.


As such, it is important to check its suitability and replace the system if necessary.
