House Extensions

House Extensions in Ilkley, Harrogate, Keighley & the Surrounding Areas


The prospect of moving to a bigger house doesn’t hold the same appeal for everyone. While for some it simply represents an unrealistic option, for others, an array of off-putting negatives soon mounts up. These include stamp duty fees, removal costs, a larger mortgage and moving out of a much-loved neighbourhood or school catchment area. It’s little surprise, then, that house extensions remain one of the most popular solutions for homeowners faced with growing families, changing circumstances or any other space and storage issues.


With dedicated teams in Harrogate, Ilkley and Keighley, Silver Birch Projects undertakes house extensions across the West and North Yorkshire region. We design and build extensions in any style or size on the land surrounding your existing property to increase the amount of living space inside it. Our team not only tailors these rooms to meet any requirement, the results also increase the resale value of the property as well.
