your trusted local builders in swanseaAll projects are different and a representative from Swansea Building Services will visit your home to discuss the wider demands of the project in person. If you are in need of any plans or structural calculations we are able to arrange an independent Architect or Engineer to conduct these on your behalf.

With our experience, we know the difficulties an extension can pose to day to day living and with this in mind a project manager will be on hand to look after every part of the build from day one.

Single Story Extensions

An single story extension will extend your property outwards, usually into you garden or patio area to create more space for a kitchen or living room. This is a great way of adding more living space to your home.


Multi-storey Extension

Multi-story house extensions in Swansea will extend outwards and upwards to give the extension a minimum of two floors, usually to the same height as your existing roof. This is a great way to add more living or storage space both upstairs and downstairs in your home.



A porch is usually a small extension to the front or side of your building. Although small a porch can ad valuable storage space in your home or be used as a small office space. A porch is a cheap way to add that little bit of extra space you might be looking for.


Over-structure extension

An over-structure extension is usually done on top of a garage or existing single story extension. Unfortunately it is not always as simple as building right on top of the existing structure, especially in the case of a garage where the supporting walls may only be single skin therefore not capable of holding the weight of another story Investigation may have to be done to the foundations of the existing building to see if they are strong enough to take the weight of another story.



A conservatory is one of the most popular ways to extend you home as it needs very little structural work to make quite a significant addition to the living space in your home. A modern conservatory is usually constructed using UPVC as it is cheaper and more durable than a lot of other materials. Wood or aluminium can be used to great effect but are normally more expensive.
