Doubling the Bungalow

DHV architects in Bristol have obtained planning consent for the redevelopment of a 1960s bungalow in South Gloucestershire.

The project comprises building a new first floor over the original single storey footprint, and extending to the front and side to increase the floor area from 120sqm to over 200sqm. As well as adding a substantial amount of floor area, this provides the opportunity for a complete exterior makeover.




The eaves and ridge will be raised by approximately 2m; the existing openings are to be re-sized; two crisp dormer windows will animate the entrance elevation and generous aluminium windows will open the rooms to the garden.

For longtime associated with declining seaside towns and ageing communities, bungalows are currently experiencing a popularity surge due to their redevelopment potential.

In desirable locations they are often purchased to be demolished and rebuilt ('bungalow eating'). Replacing an existing unit is often the only way to obtain planning consent for a new house in green belt or AONB.

When budget or planning constraints do not allow a complete re-build, a radical remodel might be a better option. This can involve: converting an existing roof-space, with or without raising the ridge; building one or more extensions; remodeling the internal layout; remodeling external openings and adding features such as dormers or chimneys; any combination of the above.

The key to these projects is to turn the existing constraints into opportunities and retain enough building fabric to avoid costs spiraling out of control. For example, an existing external wall could be turned into an internal dividing wall rather than demolished, and the boiler or the main underground drain run kept in its original location.


Each unit should be carefully assessed to find the optimal solution, however it's worth remembering that a new build will be zero-VAT rated whereas a renovation will attract 20% VAT on labour and material.
