Home Design and Planning in Southampton
Almost every project, regardless of size has some form of architectural involvement. From floorplans to detailed construction layouts, all are typically produced by an architectural team, during key project stages like concept and detailed design.
If you're competent in design, know the local policies and have access to CAD or BIM software, and providing you can articulate your requirements you can, in theory, complete things like Planning Permission yourself.
Hiring an architectural firm is a wise investment. We act as your professional guide, translating your vision into a creative, functional space tailored to your lifestyle, whilst navigating the complexities of Planning Permission and Building Control.
Builders have extensive experience of the real-world challenges of realizing a design during the construction phase. Their skills are generally construction focused, however some larger companies may be able to take on the design works in-house.
Not every project requires Planning Permission, some fall under Permitted Development or Prior Approval. It's a complex subject, but heres a rough guide.
Enlargement, improvement or alterations (e.g. rear and side extensions), additions to the roof (e.g. loft conversions, dormer windows), Porches, Buildings incidental to the enjoyment of the house (e.g. garden rooms, sheds, garages), change-of-use (class MA), minor operations (e.g. gates, fences, walls, painting).
Subject to qualification
Larger home extensions (beyond 3 or 4m), change of use from commercial (Class MA) to residential, conversion of agricultural buildings (class Q), flats ontop of existing buildings (part 20).
Subject to qualification
