Extensions are a popular way to gain space in London, where moving is expensive and gardens are often underused. Before committing, it helps to answer a few practical questions.
What do you need the space for?
A larger kitchen and dining area is the most common reason for a rear or side-return extension. A loft conversion typically adds a bedroom and bathroom. Being clear about the purpose keeps the design focused and the budget under control.
What approvals might apply?
Some extensions fall within permitted development rights; others need planning permission. Almost all need Building Regulations approval, and work close to a shared wall may need a party wall agreement. Check with your local planning authority or an architect before relying on any assumption, as rules vary between properties and areas.
Who will design it?
An architect or architectural designer can produce drawings for approvals and for the builder to price from. We are happy to work with your designer or suggest one, and we can give early input on buildability and cost.
How will the new space connect to the old?
The join between old and new is where extensions succeed or fail. Floor levels, ceiling heights, the size of the opening into the existing house and where light comes from all need thought. Matching flooring and finishes across the threshold makes the space feel like one room.
How will you live during the build?
Extensions usually mean losing the kitchen for a period. A temporary kitchen elsewhere in the house, and a clear plan for dust protection and access, make the process far more manageable.
