Double-storey extensions in Northwood

The Glen appraisal concerns maisonettes, not every Northwood home.

Identify the floors belonging to the property and provide the existing plans. A Northwood double-storey enquiry must describe the actual building, without borrowing assumptions from a different local housing form.

Begin by identifying the building and the space that belongs to the proposed project. State whether it is a house or another property form, whether access is shared and what you understand about control of the outside area. Supply relevant information rather than assuming the Northwood postcode describes a detached home or a standard plot. The Glen appraisal is about a particular development and should remain specific to it. Once the property context is clear, sketch the existing rooms and the added space you want, with any access functions that must remain. This helps establish the right questions for the designer and Falcon before an outline is treated as available land, a feasible alteration or an accepted project scope.

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.

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.

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.

Begin the project discussion with drawings and photographs of your own home. The existing Falcon galleries show specific extension and room work in New Malden and Camden. Those photographs are not presented as a completed double-storey extensions project.

Send existing drawings or safely taken property photographs to explain what you have. A finished picture can help describe a preference, but it cannot show the hidden construction or settle which alterations are suitable.

Include your actual property postcode and describe the existing plans of both floors, roof views and records of any earlier addition. In the Northwood brief, distinguish facts you know from ideas you want assessed. Keep the property, access and area you control 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.
