home extensions that improve space, light and everyday use.
We design extensions, remodels and whole-home upgrades that make existing buildings work harder without losing their character.
Whether the route is planning permission, permitted development or a lawful development certificate, we help define the right approval strategy and produce the design information needed.
Existing homes, better resolved.
One consistent LXW process, shaped around the specific approval route, design risk and technical information your project needs.
Extensions are often about more than adding floor area. The best results come from improving light, circulation, storage, structure and the way rooms connect.
We review whether planning permission, permitted development or a certificate route is appropriate before preparing drawings.
The design is then developed with building regulations, structure and buildability in mind, so the scheme can move beyond concept.

a clear route through the work.
Measured information
We establish the existing building information needed to design accurately and avoid assumptions that create problems later.
Design options
Options test the best use of budget and space, including structure, daylight, access and relationship to the garden or street.
Approvals
We identify whether the project should proceed through planning, permitted development, prior approval or a certificate route.
Technical package
The drawings are developed for building regulations, structural coordination and contractor pricing.
what you can expect.
Deliverables are tailored to the agreed scope, project stage and statutory approvals required. These are the typical information packages for this service.
Design and Planning
- Existing and proposed drawings
- Planning or certificate drawings
- Neighbour and streetscene considerations
- Planning submission support
Technical
- Building regulations drawings
- Structural engineer coordination
- Construction details
- Tender support where required
approval routes matter.
We keep the wording here conservative because planning policy, permitted development and building control requirements depend on the property, location and current regulations.
- Many extensions need planning permission, but some householder works may be possible under permitted development rights.
- Permitted development rights can be limited by site designations, Article 4 Directions, previous permissions or the type of property.
- Building regulations approval is separate from planning and may still be needed even where planning permission is not required.

common questions.
Can you check if my extension is permitted development?
Yes. We can review the project against permitted development rules and advise whether a planning application or certificate route is more appropriate.
Do I need building regulations for an extension?
Most extensions need building regulations approval, even when planning permission is not required.
