1. Introduction

Brighton & Hove’s architectural landscape is a tapestry of Regency terraces, Victorian villas, and modern builds. Many of these properties have limited floor space or layouts that feel outdated, especially if they feature heritage materials like bungaroosh. Extending your home can solve space constraints while boosting overall property value, but it requires careful navigation of local planning rules, potential conservation restrictions, and structural considerations.

Home extensions vary wildly in scope: some projects simply add a modest rear extension to create an open-plan kitchen, while others transform basements or lofts into fully liveable spaces. This guide equips you with the knowledge to approach your extension with confidence, from setting a realistic budget to preserving period character.

2. Why Extend in Brighton & Hove?

Growing Families & Lifestyle Changes
Many households in the city evolve over time—new children, remote working needs, or a desire for multi-generational living can all justify expanding a property.

Rising House Prices
Brighton & Hove is a sought-after location. By adding usable square footage, you often increase your home’s resale value, offsetting project costs.

Creative Freedom
An extension allows you to reconfigure layouts, introduce modern architecture to period homes, or blend indoor-outdoor living—especially in rear gardens.

3. Planning Permission & Local Regulations

Planning Permission Basics
While some smaller extensions fall under Permitted Development Rights, many projects—particularly those in Conservation Areas—need formal approval. The Brighton & Hove City Council website details size, height, and design requirements.

Listed Building Consent
If your home is listed, you need additional consent for alterations affecting its character. This applies to both external changes and certain internal modifications.

Building Regulations
Separate from planning, Building Regulations ensure structural stability, fire safety, and adequate ventilation. A local building control officer will typically inspect your project at key stages.

4. Conservation Areas, Listed Buildings & Bungaroosh

Conservation Areas
Brighton & Hove has many designated zones with architectural or historical significance. Extensions here must respect existing styles, scale, and materials.

Listed Buildings
Listed status protects structures of special historical or architectural interest. Extensions must preserve the building’s essential character, and you’ll likely need heritage-friendly materials and designs.

Bungaroosh
A mix of brick, flint, sand, and other rubble, bungaroosh is found in many older Brighton homes. It’s prone to moisture issues and may require specialist repairs or reinforcement before an extension.

5. Types of Extensions

Rear Extensions
Ideal for Victorian or Edwardian terraces, rear extensions can create spacious kitchen-diners or enlarge living rooms. They often incorporate large windows or bi-fold doors to bring in natural light.

Side Return Extensions
Commonly used in narrow Victorian homes, a side return extension reclaims alleyway space. This can significantly widen ground-floor living areas.

Wrap-Around Extensions
Combines both rear and side return strategies, maximising ground-floor footprint. It’s more complex and costly but can radically enhance the flow and usability of older homes.

Loft Conversions
Extend upward to create an extra bedroom, office, or studio in the attic. Not every home can support a loft conversion—check headroom, roof pitch, and structural stability.

Basement Conversions
Brighton properties sometimes feature unused or partially below-ground spaces. Converting these into habitable rooms can drastically boost living area, but they require thorough waterproofing—especially in older bungaroosh foundations.

6. Designing Your Extension

Blending Old & New
In older homes, an extension can juxtapose contemporary design with period detail, or seamlessly replicate existing styles. Consider roof pitch, window proportions, and materials.

Layout & Function
Decide whether you need open-plan living areas, extra bedrooms, or separate zones for work and relaxation. Sketch out furniture placement to ensure comfortable flow.

Light & Ventilation
Large windows, skylights, and open transitions to gardens help keep spaces bright and airy—essential in seafront climates where interior damp can be an issue.

7. Budgeting & Costs

Scope & Complexity
A basic rear extension is often cheaper than a full basement conversion or wrap-around design. Specialist heritage materials, complex demolition, or structural changes raise costs.

Professional Fees
Budget for architectural drawings, structural engineer reports, and planning application fees. Labour costs also vary based on the builder’s experience with bungaroosh and heritage projects.

Hidden Expenses
Damp issues, corroded pipework, or drainage upgrades can emerge mid-project. Always factor a contingency (around 10–15%) into your budget.

8. Securing Funding & Financing

Mortgages & Remortgaging
Many homeowners remortgage to fund extensions, especially if they have built up equity. Check interest rates and lender criteria.

Home Improvement Loans
Unsecured loans can be quicker to arrange but may carry higher interest rates than a mortgage. Always compare multiple providers.

Local Grants & Incentives
Some grants exist for eco-friendly retrofits, though availability can be limited. If your home is in a conservation area, check for heritage funding or council schemes.

9. Building Materials & Eco-Friendly Options

Matching Heritage Materials
Conservation officers often require bricks, roof tiles, or renders that mirror the property’s original finish. In bungaroosh walls, salvageable sections may need repointing with lime mortar.

Sustainable Choices
Brighton & Hove is known for its green ethos. Low-carbon concrete, reclaimed wood, or high-performance insulation can reduce your environmental impact.

Insulation & Glazing
Properly insulating the extension (walls, roof, floors) prevents heat loss. Triple-glazed windows suit windy seafront locations.

10. Working with Professionals

Architects vs. Design-Build Firms
Architects excel at bespoke designs, while design-build firms offer a one-stop shop for design and construction. Choose the model that fits your budget and vision.

Builders & Contractors
Seek out contractors with proven experience in Brighton & Hove. If your home features bungaroosh or a listed façade, confirm they understand heritage building techniques.

Project Management
Either handle day-to-day coordination yourself or hire a project manager. Managing schedules, deliveries, and subcontractors can be time-consuming but ensures details aren’t missed.

11. Timeline & Project Management

Design & Planning (1–3 Months)
Draft plans, gather quotes, and secure necessary permissions.

Preparatory Work (1–2 Months)
Order materials, clear site, arrange scaffolding. Sort out structural details (especially in bungaroosh walls).

Construction (3–6+ Months)
Timescales vary; an unexpectedly damp basement or hidden structural issues can extend the build.

Snagging & Finishing (1–2 Months)
Final inspections, painting, decorating, and any remedial works.

12. Navigating Seafront Challenges

Salt & Moisture
Sea air accelerates corrosion in metals and can penetrate walls. Weatherproofing, rust-resistant fixtures, and damp-proof membranes are vital.

High Winds
Gale-force winds off the Channel can test roofs, cladding, and windows. Ensure your extension’s structure and glazing are rated for coastal conditions.

13. Practical Tips for Daily Living During Construction

Plan Temporary Spaces
If your kitchen is out of action, set up a mini cooking area elsewhere. Secure valuables in rooms unaffected by the build.

Noise & Disruption
Builders may start early. Communicate boundaries for start/end times and be prepared for dust in shared corridors.

Waste Removal
Skips on-site must follow local council rules. Recycle or donate surplus materials where possible to maintain Brighton’s green ethos.

14. Frequently Asked Questions

How long does an extension in Brighton & Hove usually take?
A straightforward rear extension might finish in three to four months. Complex projects, such as basement digs, can take six months or longer.

Do I need planning permission for every extension?
Not always. Permitted Development Rights cover some minor works, but heritage settings often require formal planning. Check your exact location and property status.

How do I keep the heritage look of my property?
Use matching materials, replicate period details, and consult local conservation guidelines. Bungaroosh walls or listed buildings require especially careful interventions.
