House Extensions in Northwood
Rear, side-return and double-storey extension work, discussed around your existing house and the space you want to add. Tell Falcon what you want to change in your Northwood home.

Plan the new space and the rooms around it
For a Northwood extension, show the property boundaries and access arrangements you understand, while marking anything that still needs confirmation. If parts of the outside space are shared, say so rather than assuming they are part of the building site. Describe how the new room would connect to the current layout and which existing rooms would change. A house extension and alterations to part of a larger building need different starting information. Falcon can discuss the proposed work, with formal design support arranged through the partner where needed; the enquiry itself does not establish rights to build.
Choose the scope for your Northwood home
Compare the position of the addition with the room you need. Rear, side-return and double-storey options describe the footprint; a kitchen extension follows the added-space kitchen brief.
Rear extensions

A property check in Northwood
Hillingdon's appraisal describes The Glen in Northwood as a planned group of maisonettes. That specific estate illustrates why property type matters; it does not describe all Northwood homes.
Show the proposed footprint alongside the existing house when discussing the property with your designer. Confirm which current guidance applies before settling the outline.

The New Malden rear-extension gallery shows the opened rear of the house, the extension shell and fitted kitchen spaces. These are photographs of that project, with each stage kept in its original context.
Explore this Falcon projectPrepare for the first conversation
Provide a plan of the property and the proposed work, noting shared access or uncertain boundaries. Describe the new room and any fitting or internal renovation work that would accompany it.
If drawings are needed, Falcon can arrange formal design and planning support through our partner and coordinate this with the build. Our practical advice on layouts and finishes is separate from that professional work. The scope and fees are agreed for your project.
Follow the project processWhat Falcon supplies and what you choose
Falcon supplies agreed first-fix materials and carries out the agreed building and fitting work. You buy the agreed second-fix items with our guidance; Falcon fits the items included in your scope.
If your extension includes a kitchen or bathroom, discuss those purchases alongside the building work. The quote should make clear which items you need to choose and buy.
Should I mention shared outside space?
Yes. Explain the access and boundaries you understand and flag anything unresolved. The project discussion needs that context before a building outline can be treated as an agreed scope.
Can you price the work from this page?
Request a Quote for your own project. The scope, existing property and chosen items need to be understood before the price and inclusions can be explained.
Can I use drawings I already have?
Tell us what drawings and decisions are available and whether the design has changed since they were prepared. Falcon can discuss the building work against them and identify where further professional input needs to be arranged.
