Rear, side return, wrap-around, loft conversions and garden buildings. Most of our London work is on Victorian and Edwardian terraces, where the constraint is daylight: how to add depth without making the middle of the house dark. That problem shapes most of our decisions.
Sometimes not. Permitted development rights cover many single-storey rear extensions, but they are withdrawn in conservation areas, on flats, and on properties where a previous owner has already used them. We check the planning history before we draw anything.
Our fee is fixed or capped per stage. Build cost depends on size, ground conditions and glazing — structural glazing and sliding doors are usually the largest single line. We will tell you early if the scheme you are describing and the budget you have named do not meet.
Six to eight weeks to submit, eight weeks for determination if it is a householder application, then a technical design and tender period of roughly two to three months. Six to seven months before a builder starts is realistic.
Usually, though not always more than it costs. A well-planned extension that improves how the whole house works is worth more than square footage bolted on the back. We will say so if we think the money is better spent on reworking what you already have.
Two separate things. Planning consultation lets them comment on the application; the Party Wall Act gives them rights where you build on or near the boundary, and that is a legal process run by surveyors, not by the council. We flag which applies before you commit to a design.
