If you live in a bungalow in Bognor Regis, Chichester, or Arundel, you already know the unique charm of West Sussex living. You likely enjoy a generous plot of land and a quiet neighbourhood, but perhaps you’ve started to feel the "bungalow squeeze." Maybe your family is growing, you’ve started working from home, or you simply want to capture those distant South Downs views or a glimpse of the coast that the ground floor just can’t offer.
The question then becomes: Should you sell the home you love just to get more bedrooms?
At Swanbourne Construction Ltd, we’ve spent over 20 years helping homeowners realize that the answer is often right above their heads. Adding a second floor, effectively a double-storey transformation, is one of the most rewarding ways to double your living space without sacrificing your garden. In this guide, we’ll walk you through everything you need to know about turning your Sussex bungalow into a stunning two-storey home.
1. Why Upward is the New Outward in West Sussex
In many parts of Bognor Regis and Chichester, land is at a premium. Extending "out" often means losing that precious patio or lawn space. By extending "up," you preserve your outdoor sanctuary while radically changing your lifestyle.
- Protecting Your Garden: Bungalows usually sit on larger-than-average plots. Adding a second floor lets you keep your garden for entertaining while gaining the extra square footage you need.
- Capturing the View: Whether it’s the rolling hills of the South Downs or the coastal light of Bognor, a second floor provides a vantage point that a ground-floor extension simply cannot match.
- Massive Value Addition: A well-executed bungalow-to-house conversion is one of the most profitable renovations you can undertake. You are essentially creating a detached house in a market where such properties are in high demand.
2. Navigating Planning Permission in West Sussex
One of the most common questions we get at Swanbourne Construction Ltd is about the "red tape." While some smaller loft projects fall under Permitted Development, adding a full second floor usually requires a formal planning application.
Navigating the preferences of the Chichester District Council or Arun District Council requires local expertise. Planners in our area generally look for designs that are subordinate to the original structure or that fit the character of the street.
- Right to Light: This is a major factor in West Sussex planning. A second floor can cast shadows on a neighbour’s property, so the design must be carefully angled to ensure you aren't blocking their natural light.
- Ridge Heights: Planners often prefer the new roofline to be kept as low as possible. We often suggest creative roof designs, such as a "half-storey" or a mansard roof, to satisfy these requirements while still providing full-height ceilings inside.
- Conservation Considerations: If you are in a historic pocket of Arundel or near Chichester Cathedral, the rules are even stricter. For a deeper dive into these specifics, you might find our ultimate guide to planning permission in West Sussex incredibly helpful.
3. Structural Integrity: Can Your Bungalow Take the Weight?
You can’t simply "stick a floor on top" and hope for the best. Bungalows were originally designed to carry only the weight of their own roof. Adding a second floor introduces significant "dead" and "live" loads.
- Foundation Checks: Our first step at Swanbourne Construction is always a structural assessment. Sometimes, the original foundations are deep enough to handle the extra weight. If not, we use techniques like underpinning or installing a steel frame that transfers the weight of the new floor directly to new structural points.
- The "Steel Goalpost": Often, we install a series of steel beams (a goalpost frame) that supports the new floor independently of the internal walls, giving you total freedom to redesign the ground floor into an open-plan masterpiece.
4. Designing the Ultimate Layout
The beauty of adding a second floor isn't just about the new rooms; it’s about how it allows you to reimagine the ground floor.
The Ground Floor Revolution
Now that the bedrooms are moving upstairs, you can clear out the "choppy" layout of the original bungalow.
- Open-Plan Living: Imagine a vast, light-filled kitchen and dining area with bi-fold doors leading to the garden.
- The Grand Entrance: Adding a second floor gives you the opportunity to create a double-height entrance hall. This creates an immediate "wow" factor the moment someone steps through the door.
- Utility & Mudrooms: With the extra space, you can finally add that dedicated utility room or "mudroom": essential for those muddy walks in the South Downs.
The New Second Floor
- Master Suites: Most of our clients use the new floor to create a "sanctuary" master suite, complete with a walk-in wardrobe and a luxury en-suite.
- Feature Windows: Use gable-end windows or floor-to-ceiling glass to flood the new rooms with Sussex sunshine.
- Balconies: In Bognor Regis, a small Juliette balcony on the second floor can be the perfect place to enjoy your morning coffee while breathing in the sea air.
5. The Realities of the Build: Timeline and Disruption
We won’t sugarcoat it: adding a second floor is a major project. However, with Swanbourne Construction Ltd’s 20+ years of experience, we’ve refined the process to minimize stress.
- The Timeline: Typically, the construction phase for a substantial transformation takes around four to six months. From initial design to final sign-off, you should plan for a year-long journey.
- Can You Stay In? Usually, it is best to move out for the most intensive part of the build (when the roof comes off). However, we work efficiently to get the new structure "watertight" as quickly as possible.
- Weathering the Sussex Coast: Building in Bognor or Chichester means dealing with coastal winds and rain. We use advanced scaffolding and temporary roofing systems to protect your home throughout the process.
6. Avoiding Common Pitfalls
When you embark on a project of this scale, small mistakes can lead to big costs. It is vital to understand what are common loft design mistakes before you start.
- The Staircase Trap: Many people forget that a staircase takes up significant room on the ground floor. We specialize in finding "smart" locations for stairs that don't compromise your living room or hallway.
- Headroom Issues: If the pitch of your new roof isn't calculated correctly, you might end up with rooms that feel cramped. We prioritize "usable floor space" over total square footage.
- Inadequate Insulation: Modern building regulations are strict for a reason. We ensure your new floor is thermally efficient, keeping you warm in the winter and cool during those Sussex summers.
7. Is It Worth the Investment?
In 2026, the cost of moving house: including Stamp Duty, estate agent fees, and removals: can easily top £30,000 to £50,000 for a mid-to-high-range property in Chichester or Arundel.
When you compare that "lost money" to the cost of a second-storey extension, the math starts to make sense. You aren't just spending money; you are investing in equity. You are taking a property and elevating it into a different price bracket entirely.
Furthermore, you avoid the emotional toll of moving away from neighbours, schools, and the local shops you’ve frequented for years. For many, building in Bognor Regis is about more than just bricks and mortar; it's about staying rooted in the community you love.
8. Why Choose a Local Partner?
A project of this magnitude requires a builder who knows the local terrain, literally and figuratively. At Swanbourne Construction Ltd, we don’t just build houses; we build relationships.
We understand the specific soil conditions in Chichester, the planning quirks of the Arun District, and the best local suppliers for materials that stand up to the salty air of Bognor Regis. Choosing a local builder in Bognor Regis means you have an expert on hand who is personally invested in the quality of the local landscape.
