What are the benefits of converting your loft?
Loft conversions have surged in popularity across Sussex in recent years, offering homeowners an affordable way to maximise their living space and to improve the value of their homes.
✓ Add extra living space
Lack of room is the main driver behind many house moves. Transforming your loft into a stylish new bedroom, guest suite, study or games den allows you to enjoy your current home for longer.
✓ Improve energy efficiency
Around 25% of heat loss occurs through poorly insulated loft spaces. Converting your loft is the ideal time to boost efficiency, reducing your carbon footprint and saving money on energy bills.
✓ Capitalise on scenic views
Make the most of your coastal or countryside views by installing Velux or dormer windows during your Sussex loft conversion. Perfect for creating a bright, airy living space with an enviable scenic outlook.

Frequently Asked Questions
Will my loft be suitable for conversion?
The vast majority of loft spaces in Sussex can be converted into valuable living areas, although some projects may be more complex than others. Velux roof light conversions are the simplest option, while dormer loft extensions are the most popular. You’ll typically need minimum headroom of 2.2m and enough space for a staircase. We’ll survey your loft and advise on the best design choices.
Do I need planning permission for a loft conversion?
Most residential conversions in can go ahead without full planning permission, subject to certain criteria. However, it’s advisable to check with your local authority, as different rules apply for Conservation Areas, listed buildings and leaseholds. At Black Olive Construction, we provide expert guidance on any consents needed.
How long will my loft conversion take?
Timescales vary depending on the complexity and your vision. As a guide, simple Velux or dormer lofts can be completed within 8 weeks. More intricate hip-to-gable or mansard projects take longer, especially if planning consent is needed. We’ll provide an accurate timeline for your unique loft conversion.
