    Hi, I'm Michael, Managing Director of Elite Construction & Consulting Ltd, a Worthing-based building company specialising in home extensions, renovations and structural alterations throughout Sussex. With over 20 years of experience in the construction industry, we undertake everything from smaller building works to substantial extensions and complete property transformations. **Home Extensions & Renovations** A large part of our work involves helping homeowners create more space and make better use of their existing properties. Whether you're planning a single or double-storey extension, a larger kitchen and family living area, or a complete reconfiguration of your home, we have the experience and expertise to manage the entire project from start to finish. We're particularly experienced in structural alterations, including removing load-bearing walls, installing steelwork and creating large open-plan living spaces. This is often an important part of an extension or renovation, and it's an area where our technical knowledge and practical experience really set us apart. We also undertake loft conversions, garage conversions, internal alterations and general building work. **Why Choose Elite Construction?** I understand that choosing a builder is a big decision. You're trusting someone with your home, your money and, quite often, months of disruption to everyday life. Getting the building work right is essential, but so is the experience you have along the way. That's something we take very seriously. We believe a good builder should do more than simply turn up and carry out the work. You should expect clear communication, proper planning, honest advice and someone who takes responsibility for the project from beginning to end. I take a hands-on approach to our projects, working closely with our team and clients to ensure everything is properly organised and completed to a high standard. We also appreciate that many homeowners remain living in their properties during building work. We make every effort to keep disruption to a minimum, maintain a clean and safe site, and treat your home with the respect it deserves. **What You Can Expect From Us** - Proud members of the Federation of Master Builders (FMB). - £5 million public liability insurance. - Over 20 years of construction industry experience. - Experienced in extensions, complex structural work and complete renovations. - Detailed, transparent quotations with clearly defined inclusions. - Reliable, skilled tradespeople and carefully managed projects. - Regular communication and a clean, organised working environment. - Honest advice, practical solutions and a genuine commitment to quality. We take considerable care when preparing our quotations, ensuring you understand exactly what's included and how your project will be approached. We're also happy to suggest alternatives and cost-saving opportunities where appropriate. Above all, we're proud of our reputation and the relationships we build with our clients. We want you to feel confident you've made the right choice, not just when the work is finished, but throughout the entire process. If you're considering an extension, renovation or any other building project, I'd be delighted to discuss your plans, offer some practical advice and provide a free, no-obligation quotation. You're also very welcome to see examples of our completed projects or speak with previous clients. Thanks for considering Elite Construction. Michael

Questions to ask local loft conversion companies in West Sussex

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in West Sussex?

A local loft conversion company in West Sussex will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in West Sussex should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some West Sussex loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in West Sussex

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in West Sussex before agreeing to start the work.

Do I need planning permission for a loft conversion in West Sussex?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional West Sussex loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some West Sussex loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
