Feasibility FAQs

Clear answers on extensions, loft conversions, planning permission, costs, risks and typical timelines.

Line-art bird’s-eye view of a compact UK urban plot showing a terraced house footprint, garden and neighbouring properties as clean, outlined blocks. A translucent overlay outlines a potential rear extension and loft dormer zone, with simple arrows indicating access, daylight direction and overlooking risk towards nearby gardens and windows. Trees, fences and a narrow side passage are sketched sparsely but clearly. The style is precise and schematic, like an early feasibility sketch, with uniform thin lines and no text or branding. Imaginary top-down lighting keeps everything evenly legible, creating a neutral, analytical atmosphere. The composition uses the full page, with strong geometry and clear relationships between houses, boundaries and proposed building zones, supporting decisions about planning constraints and neighbour impact.
Detailed line-art cross-section of a typical UK two-storey terraced house with a loft space, drawn in a clean architectural style. The cutaway reveals rooms, staircase, roof structure and an unused darkened loft void. Next to it, a second outline of the same house shows a carefully drawn loft conversion, with dormer, new floor, roof insulation layers, and a rooflight. Light hatching indicates structure, while clear white areas suggest usable space. The setting is abstract with a simple baseline and no background clutter. Neutral, even lighting and precise, measured lines create a calm, analytical mood, like a planning or feasibility diagram. Composition is side-on at eye level, with sharp focus throughout, emphasising potential versus existing space without any human figures or text.
