Rear extensions in Gerrards Cross
A rear extension adds space behind the house. Start with the room you want to improve and the outdoor space you want to keep. Falcon can discuss the extension together with the changes needed where the new and existing rooms meet. For your Gerrards Cross enquiry, focus on garden connections and the side route.

Make the garden connection work from inside the house
The rear position is the defining choice. A kitchen extension starts with the use of the space; a side-return extension starts with an infill beside the house. A rear proposal may serve a kitchen, dining area or living room, with its layout assessed around that purpose.
Sketch the existing rear rooms, not just the proposed addition. Mark doors, changes in floor level and the route towards the garden. A larger outline can still leave a narrow or awkward connection to the rest of the house.
Discuss the wall opening, structural design, foundations and drainage as part of the building scope. Show known inspection covers and earlier additions without assuming that a cover can simply move or that an existing foundation can be reused.
Choose the relationship between solid wall, glazed doors and rooflights around the intended furniture. Consider the daylight in the room behind the extension as well as in the new space. Final sizes, structure and performance belong in the professional design and specification.
Prepare the Gerrards Cross property brief
Check Buckinghamshire’s Gerrards Cross Common and Centenary conservation maps.
Mark the garden space and access you want to retain beside the rear addition. In Gerrards Cross, check the relevant conservation map rather than assuming either named area covers the whole town.
Draw what remains outside as well as what would be built. Mark the garden route, space you want to retain and any side access that has an everyday purpose. Then connect those priorities to the proposed kitchen, living room or accommodation on both floors. For Gerrards Cross, check whether the address relates to the Common or Centenary map rather than assuming either name covers the town. This practical exercise helps the designer compare the new rooms with the setting you value. It does not imply that all garden or boundary work is included in an extension quote. List any additional outside work separately so Falcon's building scope and exclusions can be discussed without expanding the project through an undefined exterior finish brief.
Confirm the council using the property postcode and give the designer any relevant map or decision reference. A named area is a starting point for checking this address, not an assessment of the whole town. Treat sketches and examples as discussion material until the property-specific work has been reviewed.
Separate the design, building work and purchases
Our team offers practical guidance on layouts and finishes. Formal drawings and planning work are arranged and coordinated through the design partner. Practical guidance is not the production of architectural drawings; agree the professional scope and fees for your proposal.
Falcon supplies agreed first-fix materials and carries out the agreed building and fitting work. You buy agreed second-fix items, such as kitchen units, bathroom fittings and flooring, with guidance. The quote should say who supplies and fits each item, and how changes will be agreed.
Keep product choices and required delivery dates with the scope. Confirm dimensions and compatibility before buying items that affect preparation or services. If a choice changes, ask how that affects the agreed work before treating it as a like-for-like replacement.
How Falcon organises a projectDefine the budget and the programme together
The cost depends on the assessed scope, existing condition, design and chosen specification. Compare Falcon’s contract price with your total project spend: add homeowner purchases and any professional, application or other fees outside the building quote. Ask for the VAT treatment and exclusions to be explicit.
Time on site is only one part of the programme. Keep design work, property checks and approvals, lead time, procurement and construction separate when discussing dates. Explain any move, school or household commitments as requirements to discuss, not a start or completion date already agreed.

See the actual New Malden projectWhat to bring to the first conversation
Include your actual property postcode and describe the rear elevation, garden connection, access route and any previous extension drawings. In the Gerrards Cross brief, distinguish facts you know from ideas you want assessed. Keep garden connections and the side route with the drawings, and identify any decisions already made so their effect on the connected work can be discussed.
Say which drawings or decisions already exist and what still needs to be explored. Include the wider project if several services are involved. The enquiry form keeps the page you came from and lets you choose the project type that best describes your current plans.
Does a rear extension have to contain a kitchen?
No. The location of the addition and the intended room use are separate decisions. Explain whether you need dining space, a living room or a larger kitchen so the connection to the existing house can be considered.
What should I make clear in my Gerrards Cross property enquiry?
Mark the garden space and access you want to retain beside the rear addition. In Gerrards Cross, check the relevant conservation map rather than assuming either named area covers the whole town.
Does this town page establish permission for my project?
No. The property, proposed work and relevant current rules need their own review. Use the linked council resource as a starting point and arrange formal design and planning work through the partner as agreed.
Can I change the project type when I enquire?
Yes. Choose the work you actually have in mind, including Combination / not sure if needed, and enter the real property postcode. The page context helps explain what you were reading; it is not a substitute for your project details.
