Areas We Serve
Based in Benfleet, RJA works with homeowners throughout Essex and the wider South East on residential building and improvement projects.
The cost depends on the type of work, the size of the property, the specification and what needs to happen before construction begins. Extensions, renovations, loft conversions and new builds can vary considerably, which is why RJA starts with a site visit and a detailed quotation based on the actual project rather than giving a misleading one-size-fits-all figure.
Not always. Some extensions, loft conversions and other home improvements can fall within permitted development rights, while larger or more complex projects may need planning permission. Building Regulations can also apply even where planning permission is not required. RJA can help you understand what needs to be considered before work begins, while the final requirements depend on your property and proposed plans.
