Common questions about house extensions in Knowle
What types of extensions do you build in Knowle?
We build rear, side and kitchen extensions as well as larger structural projects where the existing ground floor is remodelled alongside the new space.
Every extension is planned around the individual property and the way the finished home needs to work.
Do you build kitchen extensions?
Yes. Kitchen extensions are a popular way to create a larger central living space combining cooking, dining and family areas.
Large glazing, rooflights and new connections to the garden can also help make the finished space brighter and more open.
Can you build single and double-storey extensions?
Yes. Both can be considered depending on the property, planning requirements and the amount of additional space you need.
A single-storey extension can completely transform the ground floor, while a double-storey project may also provide additional bedroom or bathroom space.
Can you extend period homes in Knowle?
Yes. Knowle has a mix of period properties, established village homes and larger family houses where the relationship between old and new needs careful consideration.
Materials, proportions and detailing can all help ensure the extension sits comfortably with the existing property.
Can you redesign the existing layout as part of the project?
Yes. An extension often creates the opportunity to improve the existing ground floor at the same time.
Structural alterations can help open up previously separate rooms and create a more practical kitchen, dining and family space rather than simply adding another room onto the back of the house.
How much does a house extension cost?
The overall cost depends on factors including size, specification, structural alterations, glazing and the amount of work required within the existing house.
Discussing budget early helps ensure the plans remain realistic and allows decisions to be made before construction starts.
How long will the building work take?
The programme depends on the scale and complexity of the project.
Once the design and specification are understood, we can explain the expected stages and provide a clearer indication of the construction timescale.
Do you work with architects?
Yes. We regularly collaborate with architects, designers and structural engineers.
Early involvement from the building team can also provide useful construction and budget insight while the design is developing.
