Business Details
We have over thirty years of experience in the building industry, having started our careers working alongside our father's building firm. As a qualified carpenter, Dave OsborneBrown brings specialised trade knowledge and a deep understanding of construction principles to every project. We established DJB Construction South Ltd in 2000 in Southampton and moved the business to Winchester in 2004, building a solid local reputation. Our firm is proud to be a member of the Guild of Master Craftsmen and the Federation of Master Builders, and we hold a place on the National Register of Warranted Builders. This accreditation demonstrates our commitment to high professional standards and quality workmanship that clients can trust. We undertake a full range of building works, including new builds, extensions, loft conversions, kitchens, bathrooms, refurbishments and landscaping, tailoring each solution to the client's needs.

Throughout every project we provide weekly or fortnightly meetings with the Director, ensuring constant communication and immediate response to any questions or concerns. Our office in Eastleigh is staffed Monday to Friday by a dedicated administrator who is available by phone or email to support clients and maintain smooth project flow. We manage projects from initial design through to completion, offering peace of mind by overseeing progress, coordinating trades and addressing queries promptly. All quotations are fixed at contract signing, with no price changes during the works, and any additional work is agreed and priced before commencement. We require an agreed deposit at the start, followed by fortnightly staged invoices payable within five working days, ensuring transparent and reliable financial management.

Services
Extensions
Extensions involve adding new rooms such as bedrooms, dining areas or home offices to an existing property. This service is aimed at homeowners whose families have outgrown their current space or whose needs have changed. By extending your home you gain extra living space, increase its market value and avoid the costs and disruption of moving.
Loft conversions
Loft conversions transform unused attic space into functional rooms such as bedrooms, studies or play areas. This service suits homeowners looking to maximise their existing footprint without altering the building's external appearance. Clients benefit from additional living accommodation, a rise in property value and the avoidance of relocation expenses.
Kitchen refurbishments
Kitchen refurbishments update outdated cooking spaces with modern fixtures, layouts and finishes tailored to the client's taste. This service is ideal for homeowners seeking a more efficient and enjoyable kitchen for daily family use. The result is a stylish, functional kitchen that enhances everyday living and adds measurable value to the home.
Bathroom refurbishments
Bathroom refurbishments replace worn suites with contemporary showers, baths and storage solutions that meet modern standards. This service targets homeowners desiring a clean, relaxing space that improves comfort and hygiene. Clients enjoy a refreshed bathroom that boosts property appeal and provides a practical upgrade without the need to move.
Landscaping
Landscaping services redesign outdoor areas with planting, paving and features that suit the property's style and the owner's lifestyle. This work is aimed at homeowners who wish to enhance curb appeal, create usable gardens or improve drainage. The outcome is an attractive, lowmaintenance exterior that increases enjoyment and adds value to the home.
