Extensions - further considerations

In general, there are three types of extension.

1. Extensions that matching the existing house. An extension that appears as if it’s an integral part of the house’s original design. This is the approach adopted by the vast majority of homeowners in Portsmouth, who try and retain the character of the existing building with the design of the extension.

2. Extensions that contrast with the existing house. An extension in the form of a radical, contemporary, architect-designed annexe to the rear, often on more than one floor.

3. Conservatories.

J.W. Williams and Sons are highly skilled and experienced at building extensions, and we pride ourselves on a top quality finish - for a free, no obligation quotation please contact us.
