Expand your home with a bespoke extension
House extensions give you the space you need without the stress of moving. From single-storey rear extensions and kitchen extensions to wrap-around, side return, and double-storey additions, each solution is tailored to your requirements in Petersfield. We also create open-plan living extensions, utility room extensions, home office spaces, and seamless garden room connections, as well as garage conversions and integrated extensions.
Opting for an extension creates additional living space, supports changing lifestyles, and can increase the value of your property. It is a cost-effective alternative to buying a larger home, allowing you to remain in the place you already enjoy. Gen 3 Construction Ltd ensures the process is carefully managed from concept to completion, so you can focus on enjoying your enhanced home. We also carry out full house renovations, helping you update, reconfigure, and improve your existing space to suit modern living.

Is a house extension right for you?
A growing family, new hobbies or the need for a home office can all mean extra space is required. Compared to the disruption of moving, an extension is often more practical and cost-effective. Gen 3 Construction Ltd supports you from the initial consultation and site visit through to design, planning, and building regulations compliance. Our team manages every stage, including groundworks and foundations, structural steel installation, and all building work. With an in-house team covering all trades, your project stays on track, and you remain informed throughout.


Benefits for your home and future
An extension creates a larger, more flexible living space and can increase your property’s value over time. You can choose layouts such as spacious kitchens, open-plan family areas, or a dedicated utility room designed around your daily routine. Our team delivers a complete service, including brickwork and roofing, windows and doors installation, electrical and plumbing works, and plastering and decorating. With full project management from start to finish, every stage is handled with care and attention, resulting in a space that works for your home now and in the future.
