Embarking on building a new home can be an exciting but challenging prospect; if you have the additional intricacies of a sloping site then careful planning is required.
There are a number of options to consider when building on a slope. One is to ‘cut and fill’; creating a level plateau by removing soil and building up the levels. This can be useful in offsetting the cost of spoil removal from site. However, this can limit the height of the proposed retaining walls, as well as affect access on steeper sites. Integrating a basement that cuts into the slope creates a lower ground level. The height can then be used to provide more even access to the upper level; with an entrance at the higher end of the slope.
Designing on a slope requires early input from a Structural Engineer; this helps to ensure the walls are designed to withstand the pressures of both the earth, and also the flow of groundwater around the walls.
Case study:
The ‘cut and fill’ theory was used on one of our recent projects; the site had existing planning permission for a new dwelling on a sloping garden. The design concept had a large cut in order to create a level area on which to build upon. Our clients wanted to create a new dwelling, but understandably use the site contours instead. Helen Needham, Architectural Department Manager met our client on site and sketched an initial concept; a basement construction method was used due to the significant slope. An oak frame vaulted storey above allowed for an upside-down house, where the living spaces were designed above ground floor bedrooms. A garage and parking area were located separately on a higher level again.
Our clients commissioned a high quality 3D topographical survey which allowed our in-house Architectural Design team to develop the scheme into a detailed planning design. This allowed the implications of the proposed design to be considered in relation to the slope and contour levels.
The design was developed and planning permission was granted. The consented drawings incorporated a garage with storage area underneath. This meant site entry and parking could sit level with access to the garage and the house. The ‘upside down’ concept provided light throughout the main living area with the bedrooms in the concrete basement. The inclusion of a wrap-around rear balcony provided access to stunning views of stretching countryside and added a connection to the garden.
There is no doubt that building on a sloping site has its own nuances. However with the advice of architects and tradesman that have specific experience of this type of build there is no reason to be put off. In some of the most successful homes we have designed and built over the years, the change in level is intrinsic to the beauty of the design.
