House extensions · Leeds

House extension design in Leeds.

Rear, side-return and two-storey extensions designed around how you live, the existing house and the practical route to approval and construction.

Start with what the existing house needs.

A successful extension is not simply extra floor area. We look at circulation, daylight, garden connection, existing structure, levels and how the original rooms can work harder before deciding where new space should go.

Typical extension projects

  • Single-storey rear extensions
  • Side-return and wraparound extensions
  • Two-storey extensions
  • Kitchen, dining and family-space remodelling
  • Garage and ancillary-space conversions

Planning and technical design

Some extension projects may fall within permitted development while others need planning permission. The appropriate route depends on the property, previous alterations, dimensions and local constraints. Once the design is approved, technical information can be developed for Building Regulations, consultant coordination and contractor pricing.
