Home Extensions in Sussex

Swanbourne Construction is a highly experienced building contractor, offering fantastic support with every aspect of designing and creating your dream extension and kitchen, whether you’d like a kitchen extension to flood your home with natural light, want to build a relaxing garden room or require extra space to accommodate a growing family.

Our multi-skilled consultants assist at each step, from assessing the best home improvement project to meet your house extension aspirations, helping with planning permission applications, and project managing the work from day one until completion.

We are committed to outstanding service, design and construction abilities, and knowledge of all the latest innovations in sustainable materials and techniques that can manage your house extension costs and provide future-proof spaces that will stand the test of time.

Every house extension is different, and we begin the process by consulting carefully with each client to understand what your living space needs to deliver and pinpointing the key features your new extension should have.

Working with Pinnacle provides the assurance of local, friendly and independent home extension guidance, including:

Consultations to discuss your existing property, the available capacity around the original house, and the positioning and dimensions of your new house extension.
Advice around layouts, features, and how to maximise your property value, such as options to create additional space through basement extensions, adding focal points like a glass roof that aid with solar gain, or calculating the proximity your proposed extension can have with your rear wall to fall within permitted development rights.
Technologically advanced modelling software to show how your house extension will look and explore finishes, textures, materials and visual impacts, enabling you to compare every option before you make any decisions.

House Extensions in west Sussex

Many of our clients wish to undertake an extension project, having seen the significant difference an extension can make, as shown on multiple property TV shows. However, they are often overwhelmed with the complexity of liaising with a local planning department, making myriad decisions about materials, designs and construction, and calculating extension costs.

We endeavour to make extension projects seamless and stress-free, with professional advice, recommendations and no-obligation consultations to ensure you are confident that you choose the right ways to enhance and extend your existing home and create the living space that will benefit you most.

Our house extensions team focuses on sustainability and can propose eco-friendly construction materials, low-carbon sourcing options, non-toxic finishes and building techniques, and how to realise your extension ideas with full compliance with all current building regulations.

Building work from Swanbourne Construction is backed by decades of expertise, our talented and capable teams of qualified tradespeople.

Choosing the Right House Extension for Your Property

Before we make any suggestions about your house extension, one of the initial tasks is to consider the size and layout of the existing house and discuss the scope of the extension you would like to build.

There are many ways to construct a house extension, so projects vary considerably, from a small kitchen extension to build outward toward a rear wall to full two-storey extension projects to double the floorspace in the original house.

Side extensions are popular for a semi-detached house, built as single-storey or double-storey extensions, using empty or redundant side returns.
A single-storey rear extension can be designed as a glazed extension to create a garden room, orangery or conservatory, or an enclosed, insulted new space such as a dining room.
Building an extension beyond the rear wall can be viable if you have a large garden or empty outdoor areas and wish to extend a detached house outward and up.
A bathroom extension above a flat roof can add substantial value, particularly for a period terraced house where older buildings were designed with compact ground floor bathrooms.
Creating a rear extension can utilise patio or garden areas and is often suitable for a terraced house where there isn’t space to the front or side aspect to extend.

We can walk through each aspect of your house extension design to advise on the right placement and size of your new extension, accounting for factors such as access, planning consent for scaffolding and other elements that may influence your decisions.
