Design Guidance

Balance Your Accommodation when extending if you are extending to add bedrooms, try and balance this by increasing the number of bathrooms. Future buyers will expect at least one bathroom and a shower room in a four or five bedroom house and without them the value will be limited. A bathroom on the ground floor of a house should be a last resort it is functional but will add little to the property’s value as bathrooms away from bedrooms are impractical and homebuyers do not like them.

we include basic 3d design with our full planning pack which can be upgraded to our interior design bolt-on allowing you to further pin point concepts allowing you or your builder clear conceptual interpretation.
