Design Options
for your Rear Extension

We can help you with architectural design ideas or indications for the cost of extension work. The planning team can advise whether a pitched roof to match the angle of the host building would be more likely to gain planning approval than a flat roof extension. Our design team will create architect drawings for both the Planning Department and for Building Control.

The Benefits

Double storey side or rear house extensions could give your family a good amount of added internal space, even if the upper storey is stepped (to avoid overshadowing). This is especially the case if your house is detached; there is ample space to the boundary; planning consents are given and your funds (for the 2 storey extension cost) can allow for the maximum extension size feasible.

However, there are certain planning routes which a good Planning Consultant can help you with, even if all the above criteria are not the case with you. Therefore it is advisable to find an architect who works with Planning Consultants in order to get you the most added value, and the optimum route for approval. They will know your local policies and what kind of design has been approved the most.

Options for Use

Your new spaces could also incorporate some internal re-configurations to add or subtract wall divisions, creating larger, open living spaces or more rooms respectively. The additional space could be a nursery, a study, a bedroom, an extra bathroom or an open kitchen / diner.
