House extensions

Rear, side and wraparound extensions, with the drawings and the construction coordinated together.

More space, planned and built as one project

An extension changes how a home works day to day. Getting the design, the approvals and the build to line up is where many projects lose time, so we treat them as one job from the first conversation.

Hamza Group can coordinate the journey from initial assessment and design through to construction and finishing, working alongside structural engineers and other specialists where the project needs them.

Need the drawings and the construction?

Many homeowners start with an idea and no drawings. We can help you move from that idea to a design that suits the house and your budget, then build it, without handing the project between separate parties.

Whether an extension needs planning permission depends on the property and its location. We help you understand the route; the decision rests with the local authority.
