If you own a bungalow in Bognor Regis, Chichester, or Arundel, you are likely sitting on a goldmine of untapped potential. Bungalows are often built on more generous plots than their modern two-storey counterparts, yet many homeowners find themselves outgrowing the "single-level" lifestyle. Whether it’s a growing family, the need for a dedicated home office, or simply wanting to capture those stunning South Downs or coastal views, the question eventually arises: Should we move, or should we grow?
In 2026, the West Sussex property market remains competitive. Between the high costs of stamp duty, estate agent fees, and the sheer stress of relocating, more residents are choosing to transform their existing footprint. At Swanbourne Construction Ltd, we have spent over 20 years helping homeowners realize that they don’t need a new postcode to get a new house. By thinking vertically and horizontally, you can literally double your square footage without losing the garden you love.
The "Upside" of Moving Up: Adding a Second Floor
The most effective way to double your living space in a bungalow is to add a full second storey or a high-specification loft conversion. Unlike a standard extension that eats into your garden, building "up" utilizes the air space you already own.
1. The Full Second Storey Addition
For those looking for a total transformation, removing the existing roof and adding a brand-new timber-framed or traditional masonry first floor is the gold standard. This allows you to mirror your ground floor footprint, effectively creating a massive four or five-bedroom home where a modest two-bedroom bungalow once stood.
Structural Integrity: Before we lift a single tile, our team conducts a thorough assessment of your existing foundations. Most mid-century bungalows in areas like Westergate or Aldwick were built with robust footings, but adding a full second floor requires expert engineering to ensure the weight is distributed correctly.
2. High-Impact Loft Conversions
If a full second floor feels too ambitious, a "hip-to-gable" or "Dormer" loft conversion can still provide significant gains. By extending the sloping side of your roof (the hip) into a vertical wall (the gable), we create enough internal volume for two large bedrooms and a family bathroom.
Creating Height: To meet building regulations, you generally need a minimum of 2m of head height. If your current loft is too shallow, we can often lower the ceilings of the rooms below or raise the ridge line of the roof to make the space habitable and airy. For inspiration on how this looks in practice, explore our loft conversions in Chichester.
Expanding the Footprint: The Power of the Wraparound
While building up is excellent for bedrooms, building out is how you create that "wow factor" living space. In Bognor Regis and Arundel, many bungalows feature large rear gardens that can easily accommodate a significant extension.
The Double-Storey Rear Extension
By combining a ground-floor extension with an upward build, you create a "wraparound" effect. This is the ultimate strategy for doubling square footage. You can gain a massive open-plan kitchen and dining area on the ground floor, while simultaneously adding a master suite with a balcony above.
Internal Reconfiguration
Doubling your space isn't just about adding new rooms; it’s about making the old ones work harder. We often find that bungalow layouts from the 1960s and 70s are "room-heavy" with narrow corridors. By knocking down internal walls and integrating the new extension, we create a flow that makes the entire house feel twice as large, even before you factor in the new upstairs.

Navigating the West Sussex Planning Landscape
One of the biggest hurdles homeowners face is the fear of planning permission. However, the landscape in 2026 is more "renovator-friendly" than you might think.
- Permitted Development (PD): Many bungalow transformations fall under Permitted Development rights. This means you can often add significant volume to the rear or side of your home without a full planning application, provided you follow specific criteria regarding height and materials.
- Conservation Areas: If you are lucky enough to live in the historic center of Arundel or Chichester, rules are stricter. At Swanbourne Construction Ltd, we have two decades of experience working with local councils to ensure designs respect the heritage of the area while still delivering the modern space you need.
- The 50% Rule: Generally, you can extend your property by up to 50% of the area of land around the "original house" (as it stood in 1948 or when it was built). This is a generous allowance that makes doubling your square footage a realistic goal for many detached bungalows.
Aesthetic Unity: Making It Look Like One House
A common concern is that a transformed bungalow will look like a "house with a hat on." Our goal is to ensure the finished product looks like a cohesive, architecturally designed home.
- External Cladding: Using modern materials like Cedral weatherboard or contemporary render can unify the old brickwork of the ground floor with the new structure above. This is particularly popular for builders in Bognor Regis, where coastal-inspired cladding provides both aesthetic appeal and protection against the sea air.
- Uniform Glazing: Installing new, high-performance windows throughout the entire property (rather than just the new section) is the secret to a seamless look. In 2026, we are seeing a huge trend toward slimline aluminum frames that maximize light and bridge the gap between traditional and modern styles.
The Financial Reality: Why Renovating Wins in 2026
You might wonder if the investment is worth it. Let’s look at the numbers. The cost of moving to a house that is double the size of your current bungalow in West Sussex often involves:
- Stamp Duty: Potentially tens of thousands of pounds that you never see again.
- Estate Agent Fees: Usually 1-2% of your sale price.
- The "Premium": Large houses in Chichester and Arundel carry a significant price premium.
By investing that same capital into a Swanbourne Construction Ltd transformation, you are not just spending money; you are building equity. You are taking a property with a lower market ceiling (a bungalow) and elevating it into a high-value family home category.
The Lifestyle Impact: More Than Just Bricks and Mortar
Beyond the square footage, think about how your life changes when you double your space.
- Privacy: Moving the bedrooms upstairs allows you to keep the ground floor as a dedicated social and entertaining hub.
- The View: In West Sussex, a second storey often reveals views you never knew you had: the spire of Chichester Cathedral, the battlements of Arundel Castle, or a glimpse of the English Channel.
- Future-Proofing: You can design the ground floor with "living in place" in mind (keep a spare room and bathroom downstairs) while using the upstairs for family life now.
